  • Bio- and Phytoremediation of Pesticide-Contaminated Environments: A Review
    • Authors: N. Eevers; J.C. White; J. Vangronsveld; N. Weyens
      Abstract: Publication date: Available online 11 March 2017

      Pesticide-contaminated fields can be found worldwide due to excessive use of insecticides, herbicides and fungicides. Many of the pesticides that were once used intensively are now forbidden and have been shown to have deleterious health effects. Plants, bacteria and fungi have been shown to possess pesticide-degrading capacities, which can be applied in the successful remediation of contaminated fields and water. This article will first provide an overview of the different types of pesticides, their application and their key characteristics, followed by an analysis of their behaviour in the environment. Pesticides that are introduced into the environment seldom stay where they were applied. A complex system of transport, transfer and transformation of pesticides throughout different environmental compartments often takes place. These processes all influence the possible remediation of the pesticide-contaminated media. We will then review several possible remediation strategies that are currently available. Bioremediation is the first technology that is reviewed. With bioremediation, the focus is on the remediation of pesticides by microorganisms in bulk soil, without the aid or presence of plants. Second, plant-associated remediation is discussed. When focussing on plant-associated remediation, a distinction has to be made between rhizoremediation in the rhizosphere and phytoremediation within the plant tissues. While rhizoremediation and phytoremediation processes are possible solely with the use of plants, many of these processes are optimized by associations between plants and microorganisms. Plants and bacteria or fungi often live in a symbiotic relationship that aids them in surviving contaminated environments, as well as with the degradation of the contaminants they encounter. In the last part of the review, we discuss the advantages and disadvantages of “natural” remediation strategies as compared to more classical industrial approaches.

  • Molecular and Cellular Aspects of Contaminant Toxicity in Plants: The
           Importance of Sulphur and Associated Signalling Pathways

      Environmental contamination with metals and organic compounds poses a serious threat to human health. Investigating plant responses to these contaminants at the molecular and cellular level is crucial to optimize phytoremediation strategies to clean up contaminated soils. Two key players in plant stress responses are the sulphur-containing amino acids cysteine and methionine. Cysteine is an important constituent of the metal-chelating metallothioneins and is also the precursor for glutathione and subsequent phytochelatin synthesis. During stress conditions, glutathione is involved in (1) metal chelation, (2) xenobiotic detoxification and (3) antioxidative defence. The activated form of methionine, S-adenosylmethionine, is involved in the synthesis of ethylene and polyamines, both playing important roles in signal transduction. This review provides an overview of sulphur uptake and assimilation and its conversion into basic metabolites essential for detoxification and signal transduction during metal and organic contaminant exposure in plants. Furthermore, the cross talk between these pathways and their relation to the contaminant-induced oxidative challenge are discussed.

  • Allelopathy and the Role of Allelochemicals in Plant Defence
    • Authors: S. Latif; G. Chiapusio; L.A. Weston
      Abstract: Publication date: Available online 16 February 2017

      Author(s): S. Latif, G. Chiapusio, L.A. Weston
      Allelopathy is described as the interference to plant growth resulting from chemical interactions among plants and other organisms mediated through release of plant-produced bioactive secondary metabolites referred to as allelochemicals. A number of mechanisms have been studied for the release of allelochemicals from various plant tissues including volatilization or leaching from aerial parts, exudation from roots and decomposition of plant residues in soil. Despite differences in biological activity and mode of action, related compounds commonly share similar biosynthetic pathways while some classes of metabolites can be produced using diverse biosynthetic pathways. Recently considerable research has also been undertaken to critically understand the role of allelochemicals in plant succession and plant invasion in native and nonnative ecosystem. In addition, numerous studies have been performed on the selection and utilization of weed suppressive crops and their residues for weed management in sustainable agriculture systems. A better understanding of allelochemical production with respect to plant defence strategies, both physical and chemical, may also allow us to better protect and manage developing crops, limit the spread of invasive weeds, preserve native plant stands and create strategies for allelochemical development and application as novel pesticides. The use of sensitive analytical techniques associated with performance of metabolomics in concert with other omics technologies has led to new advances in the identification of unique allelochemicals, the biosynthetic pathways associated with their production, their complex role(s) in the soil rhizosphere and their production as impacted by a changing climate. Identification of novel plant metabolites, including allelochemicals, may result in a source of biologically based pesticides through the provision of complementary structures for future synthesis and as an aid in the development of new molecular target sites.

      Air pollution has become a global problem and affects nearly all of us. Most of the pollution is of anthropogenic origin and therefore we are obliged to improve this situation. In solving this problem basically our only partners are plants with their enormous biologically active surface area. Plants themselves are also victims of air pollution but because they are sedentary they developed very efficient defence mechanisms, which can also be exploited to improve the humanosphere. For their life processes plants require intensive gas exchange, during which air contaminants are accumulated on leaf surfaces or absorbed into the tissues. Some of the pollutants are included by plants in their own metabolism while others are sequestered. In some plant species, the processes of removing pollutants from the air is conducted in a very efficient way and therefore they are used in the environmental friendly biotechnology called phytoremediation. For urban areas, outdoor phytoremediation is recommended while indoor phytoremediation can be applied in our homes and workplaces. Because in near future purifying outdoor air to protect human health and well-being does not look the most promising, an important and increasing role will be played by indoor phytoremediation.

      Hyperaccumulator plants can take up large amounts of metals in their shoots without showing significant signs of toxicity. This makes hyperaccumulators ideal candidates for metal phytoremediation and phytomining. Hyperaccumulation of metals does not only depend on the bioavailability of the metals in soil and the expression of detoxification genes and metal transporters provided by the plant, but also on the plant-associated microbiota. Studies using culture-dependent strategies have shown that hyperaccumulator plants carry a high diversity of bacteria and fungi in the rhizosphere and endosphere, some of which are shown to have potential for assisting plants to grow in metal-contaminated soil and regulating plant metal uptake. However, there is yet little information available about the total microbial communities and their functions associated with the majority of hyperaccumulators known to date. Culture-independent molecular techniques and next generation sequencing allow to uncover a broader diversity of microbial species than the classical 1% cultivable fraction and can provide unprecedented insights in microbial community functions. Some unique microbial groups that are highly abundant in heavy contaminated sites have been detected in this way and have great potential for improving the efficiency of metal phytoextraction. This chapter provides the latest insights in the plant-associated microbiota of common hyperaccumulator plant species and discusses on the implications, and future prospects, of exploiting the microbiome for enhancing metal uptake by plants.

      Soil contamination is a major environmental problem affecting human health worldwide. A sustainable solution for this contamination is phytoremediation, a technique that has gotten more and more attention over the past decade. In this chapter, we will discuss how mycorrhizal fungi (arbuscular mycorrhizal fungi, ericoid mycorrhiza and ectomycorrhiza) can assist in phytoremediation. Our aim is to evaluate the benefits and drawbacks of mycorrhiza-assisted phytoremediation, review examples from literature, and provide recommendations for future studies. Both inorganic and organic pollution and factors influencing the effect of mycorrhization will be addressed. Furthermore, molecular mechanisms associated with the beneficial effects of mycorrhizal inoculation will be discussed. Since there are a number of studies (34) reporting quantitative data on the effect of mycorrhizal fungi on organic soil pollution, a meta-analysis was performed to quantify the influence of mycorrhiza on the degradation of organics. Although the effects of mycorrhization are highly variable, it is clear that mycorrhizae have the potential to enhance the phytoremediation efficiency of organic as well as inorganic pollution. Mycorrhiza-assisted phytoremediation is thus a valuable strategy for the remediation of contaminated areas and should be further studied.

      For years, metallophytes of both natural and human-influenced metalliferous soils have focussed considerable attention due to their unique appearance and ability to colonize often extremely harsh habitats. A majority of metal-contaminated areas comprise serpentine (ultramafic, rich in Ni, Cr and Co) and calamine (rich in Zn, Pb and Cd) soils hosting characteristic serpentine and calamine flora, which is the focus of this review. Through microevolution, the plants inhabiting metalliferous habitats have developed a range of intriguing adaptive traits, demonstrated as characteristic morphological, behavioural and physiological alterations that enable them to avoid and/or tolerate metal toxicity. The mechanisms responsible for protection of the plant cell from metals entering the protoplast as well as for detoxification of toxic metal ions inside the cell by chelation, vacuolar sequestration and exclusion from the protoplast are reviewed. These mechanisms have resulted in highly specialized plants able to hyperaccumulate or avoid metals in the shoots. Potential applications of both kinds of metallophytes in rehabilitation and phytoremediation of metal-polluted sites are briefly discussed. Moreover, other beneficial applications of metal-rich plant biomass are mentioned, e.g., as a bio-ore for precious metal recovery (phytomining, agromining), a by-product for eco-catalyst production or a natural source of micronutrients that are essential for human diet and health (biofortification). The need of active protection of metalliferous sites and conservation of metallophyte biodiversity is pointed out.

      Phytoremediation of inorganics is comprised of technologies to protect the environment from contaminated soils. This broad group of technologies includes phytoextraction (removal from soil), phytomining (accumulating economic metal value in plant biomass) and phytostabilization (limiting plant metals and soil metal uptake and/or bioavailability using plants and soil amendments). As agronomic technologies, selection of plant genotypes, management of soil properties, appropriate use of fertilizers and soil pH adjustment amendments are required for optimum effectiveness. Phytoextraction depends on the availability of plants which can accumulate and tolerate ∼100-fold higher metal concentrations than tolerated by common crop species. Unless a plant can accumulate over 1% (10g/kg) of a metal in dry shoot biomass, it is unlikely to remove metals rapidly enough to support economic remediation. For element cases where contamination is low (Cd), plants which accumulate over 1000μg/g may be able to achieve adequate phytoextraction. In the case of Ni, the combination of extensive ultramafic soils rich in Ni, and natural hypernickelophores (accumulate over 10g Ni/kg) with high harvestable biomass yield allows a phytomining technology to be profitable. Increasing knowledge of the biochemistry and genetic mechanisms used by hyperaccumulator plants portend the day that high biomass element hyperaccumulator plant genotypes can be constructed for soil remediation in all climatic zones.

      Plants face the problem that they have to discriminate symbionts from a diverse pool of soil microbes, including pathogens. Studies on different symbiotic systems revealed commonalities in plant-microbe signalling. In this chapter we focus on four intimate symbiotic interactions: two mycorrhizal ones, with arbuscular- and ectomycorrhizal fungi, and two nitrogen-fixing ones, with rhizobium and Frankia bacteria. Comparing these systems uncovered commonalities in the way plants attract their symbiotic partners. Especially flavonoids, and in a lesser extent strigolactones, are pivotal plant signals that are perceived by the microsymbiont. In response, signal molecules are exuded by the microbes to trigger symbiotic responses in their host plant. Strikingly, microbes that establish an endosymbiotic relation with their host plant, namely arbuscular mycorrhizal fungi, rhizobium and Frankia bacteria, make use of a symbiotic signalling network that is highly conserved in plants. The use of flavonoids as attractants for symbiotic microbes, in combination with the use of a common plant signalling network to establish endosymbioses, raises questions about how plants manage to discriminate their microbial partners.

      Plants interact closely with microbes and these can enhance plant growth and health by increasing nutrient uptake and improving plant resistance to pathogens and stress. Plant-associated microorganisms are commonly used as ‘biofertilisers’ in agriculture but their incorporation into phytoremediation systems to improve plant establishment and growth, and modify plant metal accumulation, is more recent. This review focuses on the recent advances in the use of plant–bacterial associations to enhance phytoextraction (phytomining) processes in trace element (TE)–contaminated or –enriched sites. Experimental evidence shows that plant-associated bacteria play an important role in plant TE bioaccumulation, and bench level studies suggest bacterial inoculants could enhance phytoextraction efficiency. However, the performance of these bacterial inoculants under natural conditions will have to be investigated under a field scale.

      In this study, we review recent works in the phylogenetic investigations of plant–insect interactions. Thanks to the development of novel methodological approaches and the ever-increasing availability of informative molecular markers, it is indeed now possible to test more and more complex evolutionary scenarios. Here, we are limiting our review to studies on herbivorous insects (excluding work on the evolution of pollinating insects), and we provide an overview of the variety of approaches employed to answer fundamental questions in plant/insect evolution. More specifically, our review addresses studies that have focused on the following: (1) reconstructing the evolutionary history of the associations with plants; (2) inferring the diversification dynamics of herbivorous insects and (3) studying the biogeographic history of herbivorous insects. Finally, we attempt to decipher whether general trends in the evolution of plant–insect interactions have emerged from these studies and highlight the most promising perspectives in this field.

      Flowers are a remarkable component of everyday life. Their diversity of shape, colour and fragrance witnesses the importance of the joint evolutionary processes resulting from the interactions between plants and their insect pollinators. Indeed, pollination mutualisms with insects are key factors that have allowed the evolutionary success and diversification of flowering plants (McKey & Hossaert-McKey, 2008). This diversification of plants has led to an even more impressive diversification of insects. This chapter retraces the main steps of the past history of diversification of pollination interactions with the emergence of some major pollinator groups of insects and proposes some insights into the selective processes acting on the evolution of the entomophilous pollination.

      Parasitism by sedentary plant-parasitic cyst and root-knot nematodes exhibits intriguing and fascinating examples of plant modifications induced by animals. This is reflected by the ability of these parasites to locate host plants, to trigger plant responses when approaching host roots and to induce the redifferentiation of plant root cells into specialized feeding structures. This chapter reviews current knowledge of the many layers of communication and signal exchange between plant-parasitic nematodes and host plants. In particular, it highlights host- and nematode-derived chemical signals and bioactive compounds that may facilitate plant–nematode recognition. In addition, this chapter emphasizes how this recognition results in the formation of nematode feeding sites and describes the underlying molecular mechanisms, which involve both nematode secretions and host factors.

      Plants are surrounded with microorganisms whose abundance is promoted by the release of plant organic compounds and by the presence of niches favourable to microbial development and activities. These microorganisms thrive in three main plant compartments, i.e., spermosphere, rhizosphere and phyllosphere, which are interconnected. They are recruited from the environment (soil, atmosphere) and from the mother plant via the seed. Plants indeed modulate the composition and activities of the hosted microbial populations through complex communication trackways relying on trophic interactions and/or molecular signalization. The tuning of these interactions by the plant favours beneficial microbial populations and activities while depressing deleterious ones, which have a major impact on plant growth and health. This review presents the current knowledge of the plant communication with associated microorganisms in the spermosphere, rhizosphere and phyllosphere and of plant and microbial traits involved. Possible prospects of application of this knowledge for monitoring plant–microbe interactions in agroecological systems with reduced chemical inputs are discussed.

  • Mimicry and Deception in Pollination

      Mimicry and deception in pollination represent extended plant–pollinator communication systems including two senders of mistakable signals. Flower mimicry is a highly diverse phenomenon including Batesian mimicry, in which a nonrewarding flower mimics a rewarding one, and signal standardization, also known as Mullerian mimicry, in which two unrelated rewarding flowers display similar signals. In these floral mimicry systems, even experienced flower visitors are deceived. Some flowering plants exploit the pollinators' innate preferences of finding rewarding flowers or floral rewards: In some cases the flowers fit the innate search image of flower visitors so close that no real model exists. In other cases, only the floral reward is mimicked. Particularly, pollen and stamen mimicry systems are very common, in which flowers mimic visual and tactile signals of pollen and stamens, and by means of this fake stamens and pollen deceive or misdirect pollen-eating and pollen-collecting flower visitors that innately respond to these signals. In another type of floral mimicry, animal-pollinated flowers attract flower visitors by mimicking features related to aspects other than flower visitation of their pollinators, e.g., sexually deceptive flowers deceiving mate-seeking male insects, and brood-substrate mimicking flowers deceiving females searching for egg-laying substrates. These deceptive flowers attract specific pollinators by means of sensory exploitation of a well-developed innate behavioural response for distinct volatiles and other cues that have evolved in the context of mating or egg-laying behaviour. Floral mimicry is always beneficial for the mimic, but may impose costs for the deceived pollinators. Then the deceived pollinators likely evolve mechanisms not being deceived and the flowering plants to continue deception, and deception becomes trickier over evolutionary times.

      Phytophagous insects have developed mechanisms of various complexity levels to utilize plants in spite of the barriers that plants have built to resist aggressions. Plant exploitation, the simplest level, is the use of plant defence chemicals for the benefit of insects. It is illustrated by the use of plant toxins for defence against predators. The energetic cost of that defence strategy is discussed according to the toxicity of the chemicals and the necessity of protecting the herbivore, and the modes of action on predators are presented. Furthermore, manipulation of the plant can reorient the plant metabolism to satisfy insect needs. Drastic remodelling of the host plant can occur, from ultrastructure to anatomy levels, with alteration of both its nutritional quality and secondary metabolism. The mechanisms involved are being investigated. Outcomes concern optimization of the nutritional value of the host plant and protection from adverse abiotic and biotic (natural enemies, competition) conditions. Cooperation with conspecifics or microorganisms often interferes. At the highest level of complexity, mutualism is the result of a compromise between insect and plant where each partner benefits from the association. Pollination is a typical example. Pollinators vary from generalists to specialists and belong to a community of insect linked to a community of plants. In the fig–fig wasp mutualism, the various mechanisms involved in situations of monoecy and dioecy are discussed, as well as the existence of coadaptations and cospeciations. The chapter ends with a presentation of research perspectives for improving crop productivity.

      Chemical signals are important cues throughout the life of an insect especially for mate location and for prey and host finding. The chemical signal, whether pheromone or plant volatile organic compound (VOC), remains specific because of the mixture, of the ratio of the components in mixture and of the release quantity. The plasticity of pheromone emissions is now studied in several insect species in relation to geographic variation, host plant specialization and chemical and light environment. The actual vision is that the pheromone composition is likely to be more plastic than previously assumed. The perception of the environmental odorscape produced by living plants and animals together addressed the question on the specific detection of the pheromone signal in the atmospheric blend of molecules. In agrobiocoenosis, the cultivated plants produce a specific odorscape. The insects rely on plant VOCs to locate the crop or the host plant, after which specific mixtures act as oviposition stimulants. The insect responses to host plants and their odours vary with the physiological status of both actors: the plant and the insect. Chemical signals released by plants vary with plant physiology, diel periodicity, climatic factors and pollution, and these signals can be species or even variety specific. Many of plants signalling compounds detected by insects have important roles as warning signals, which can also function in plant–plant communication.

      The communication between flowers and pollinators is the essential feature of sexual reproduction in zoophilous flowering plants and helps to ensure pollen transfer between flowers of conspecific plants. The plants' side of communication between flowers and pollinators includes the display or concealment of primary attractants, such as nectar, pollen or other kinds of floral rewards, and of secondary attractants of flowers and inflorescences to enable detection and discrimination by pollinators. These secondary attractants constitute the signalling apparatus of flowers with their visual, olfactory, gustatory and tactile signals addressed to potential pollinators. The flower visitors' side includes the various sensory capabilities of different flower visitors and their abilities to handle flowers. Because the attributes of flower visitors needed to handle flowers differ largely among bees, flies, beetles, birds, bats and others, many flowering plants have evolved flowers adapted to one particular group of pollinators and consequently emit signals to attract their specific pollinators. Selective attraction of pollinators and deterrence of flower antagonists by means of specific signals, innate and learnt preferences of flower visitors as well as sensory exploitation make communication between flowers and pollinators a highly complex and diversified interaction.

      Parasitic plants are usually considered as botanical curiosities because of their shapes and colours. However, in some cases, they are proving to be terrible bioagressors in man-made ecosystems. Parasitic plants have indeed the capacity to connect intimately with other plants to exploit their resources (water, nutrients, growth regulators…) for their development. Thus, these plants are the result of an evolutionary transition from autotrophism to heterotrophism. The underlying process of this trophic exploitation, governed by a fine-tuned molecular dialogue between both partners, is an extraordinary example of adaptive plant biology operated by these parasitic organisms in the course of evolution. This transition is associated with remarkable morphological and physiological adaptations, and these adaptive strategies have led some parasitic plants to become deadly pests for crops against which no efficient control methods are yet available, especially in terms of sustainability. This chapter highlights the actual knowledge regarding the molecular aspects of these intimate and intriguing communications between host plants and parasitic plants, with a special focus on root parasitic plants.

      There is growing evidence that microorganisms are important ‘hidden players’ in insect–plant interactions. Insect symbionts can directly affect these interactions by providing insects with key nutrients or by interfering with the plant to modulate food provisioning to insects and plant defences. Insect symbionts can also have indirect cascading ecological consequences at the community level through insect- and plant-mediated effects that include their impact on insect reproduction, on natural enemies of herbivores or on plant-associated microorganisms. Identification of symbiotic communities associated with insects, characterization of transmission and acquisition patterns as well as understanding of molecular mechanisms underlying these plant–insect–microbe interactions have important ecological and evolutionary consequences. This review highlights the excitement that surrounds these investigations and the promise they hold for a better understanding of the functional, ecological and evolutionary impacts of symbionts on plant–insect interactions, with implications and relevance for both applied and fundamental researches.

      Mycorrhizal fungi can interconnect individual plants to form common mycorrhizal networks (CMNs). Recent work has shown that these networks can transport signals produced by plants in response to herbivore and pathogen infestation to neighbouring plants before they are themselves attacked. The speed of transfer to uninfested plants is such that the mechanism is likely to have measurable benefits for plant protection. At present, the nature of the signals and the degree of plant and fungal control of their delivery are unknown. Interplant communication of signals via mycorrhizal fungi means we must rethink our understanding of multitrophic interactions in nature, and the findings have led to several hypotheses concerning the evolutionary outcomes of the process. We urgently need to better understand the mechanisms of signal transfer in natural plant communities, and attempt to harness the formation of CMNs as a tool for sustainable pest management in agriculture.

      Trophic relationships between plants and insects are not confined to biological interactions such as herbivory (i.e., direct consumption of one primary producer by a predator). In an ecological approach, many other interactions, trophic or even nontrophic, may influence plant herbivory by insects. These interactions are related to the complexity and the diversity of the fauna and flora. Plants and insects own to food webs, characterized by properties emerging from the identity of organisms and from the organisation of the links they develop with each other. These organisms can be considered as both taxonomic and functional units of biodiversity highlighting the complexity of food webs. Insects can be predated (e.g., by other arthropods or birds), parasitized and competed with for resources. Plant competition and availability of resources for primary producers may also influence the relationship between plants and their consumers. The inclusion of predation mechanisms in plant–insect interactions leads to the theory of trophic cascades that advanced our understanding of the process of herbivory by insects. Ecological theories give a framework to assess the way by which these biotic interactions may be controlled in natural systems. Trophic cascades provide also biological tools for the management of agroecosystems, especially for biological control of herbivores and the promotion of biodiversity. Biological interactions within food webs may also be nontrophic and alter plant–insect herbivory. Intraguild competition, interference, abiotic resources, microclimate and changes in animal behaviour are some of the drivers which may influence plant and insects, and thus their trophic relationships.

      Populations of herbivorous insects are naturally consumed by other predacious or predatory insect species. These entomophagous insects are thus plant-dwelling organisms that use the plant for several vital functions and are affected by plant traits at the evolutionary, organism and population levels. Many entomophagous species are used for the biological control of insect pests worldwide. The aim of this chapter is to provide an exhaustive review of mechanisms underlying the interactions between plants and entomophagous insects, including those governing life history traits at the individual level, as well as those acting on population and community structure and dynamics. We detail how properties of host-infested plants determine parasitism behaviour, development (in the case of parasitoids) and nectar consumption by adult entomophagous insects. We detail how plants respond to and benefit from natural enemies attacking insect herbivores. We also illustrate how plant architecture, the vegetation communities and their climatic correlates can influence predator and parasitoid behaviour and populations. This chapter considers the biology and ecology of the interactions and mentions some implications for the biological control of plant pests.

      Pathogenic fungi and oomycetes can establish intimate associations with plants. These interactions underlie a molecular dialogue that leads to the successful colonization of host tissues. Major questions driving research in plant pathology these last decades are how pathogenic microorganisms circumvent preformed or induced defences and how pathogens manipulate host physiology to promote virulence. One key actor in this dialogue relies on a class of molecules secreted by pathogens termed effectors. Effectors perturb host processes by targeting a variety of host functions either in the apoplast or in the cytosol of host cells. This chapter focuses on fungal and oomycetal cytoplasmic effectors by reviewing methods to predict and to characterize effectors as well as their activities and role during infection. We provide current knowledge regarding their evolution and their putative role in the shaping of plant-associated microbial communities.

  • From the Lab Bench to the Forest: Ecology and Defence Mechanisms of
           Volatile-Mediated ‘Talking Trees’

      Transfer of information is important for almost all biotic interactions, but has received less attention in plants. Volatile organic chemicals (VOCs) emitted from floral tissues and green tissues of plants affect how plants interact with each other (informally termed ‘plant communication’), with mutualists such as pollinators and with enemies such as herbivores. In this chapter, we give an overview of VOC-based plant communication, in which plants that eavesdrop on VOC signals emitted from neighbouring herbivore-damaged plants increase their defence. While historically controversial, recent research has begun to establish the details of these interactions in various plant systems, including the identity of the VOC signal, the mechanism of VOC perception and the transduction pathways that link VOC perception to a defensive response. At the same time, ecological studies have begun to establish the evolutionary drivers of plant communication. Key insights from these studies are that these responses are kin-specific, memorable and mediated by known internal defence signals and epigenetic regulations in plant cells. Moving forward, studies that connect our increasing understanding of the mechanisms of plant–plant communication with their ecological consequences will help determine the importance of this type of defensive induction as well as the targets of selection within the plant–plant communication apparatus.

  • Plant Communication With Herbivores

      Plants and herbivores both release volatile organic compounds that have important roles in mediating important biological functions related to defence and reproduction. Plants emit complex blends of chemicals that are involved in multitrophic interactions, coordination of systemic defence responses and pollination, whereas herbivorous insects release pheromones that play important roles in attracting mates, instigating defence responses and initiating aggregation. Interactions between plants and herbivores have been subject to a wealth of studies and knowledge on their biology, biochemistry, ecology and evolution is constantly expanding. In this chapter the idea of communication between plants and herbivores will be explored. Communication between organisms of consecutive trophic levels is somewhat controversial due to unidirectional reliance and competition precluding some of the requirements of a conventional communication process, but there are growing examples of where chemically mediated interactions between plants and herbivores can be viewed as eavesdropping by a signal recipient, or even as true communication where both chemical emitter and receiver gain a benefit from communication. Examples of herbivores responding to plant-emitted cues and plants responding to herbivore-emitted cues are both explored, and suggestions for future directions in this field are provided.

      Host plants possibly represent the strongest selection pressure for the evolution of reproductive traits in phytophagous insects. In a first part of this chapter, we review how plant quality affects both female and male life history traits and their respective reproductive success, and how the production and transfer to females of male sperm and associated nongametic substances (spermatophores as nuptial gifts) also depend on the host plant choice. At first glance, it seems that reproductive traits in phytophagous insects should be selected to maximize the success of this short-term interaction between host plant and phytophagous insects. This, however, ignores the fact that variation in reproductive success is detrimental to long-term fitness, which may explain that reproductive traits depart from their short-term expectation in unpredictable environments. Bet-hedging strategies – as exemplified by spatial or temporal dispersal (e.g., prolonged diapause) – can therefore evolve in such environments, as described in the second part of this chapter. The knowledge reviewed in this chapter is also integrated in the broader applied perspective of insect pest population management.

  • Chatting With a Tiny Belowground Member of the Holobiome: Communication
           Between Plants and Growth-Promoting Rhizobacteria

      As sessile organisms, plants have facilitated to actively protect themselves against biotic and abiotic stresses. For this, plants keep communicating with other organisms including insect and microbes inside and outside plant surface including root surface. In the area around the root referred to as the rhizosphere, diverse root-associated bacteria interact with plants with both positive and negative effects. In the past three decades, a group of rhizosphere bacteria known as plant growth-promoting rhizobacteria (PGPR) have been intensively studied for possible use in improving plant health. Here, we provide an overview of the current knowledge on the nature of PGPR, their signatures and their roles in plant growth promotion and biological control against plant pathogens, as revealed by classic physiological and morphological observations and recent cutting-edge technology. We also discuss new information on insect–plant–PGPR tritrophic interactions, as well as technology transfer from the laboratory to the field. We use the new concept of the holobiome to help elucidate plant–PGPR interactions. Understanding plant root–bacterial communications in this novel framework may facilitate the improvement of plant health in agricultural production systems.
