  • Metabolomics - what nomenclature to use'

    • Authors: Tamas Komives
      Pages: 1 - 3
      Abstract: This Opinion paper was written to initiate a discussion on the nomenclature used in metabolomic studies. The paper is based on the belief that the currently used classification of metabolites as "primary" and "secondary" are inaccurate and somewhat misleading. Of the alternative names previously suggested in the literature we strongly support the use of the names "general" and "specific metabolites".

  • Research directions in plant protection chemistry

    • Authors: Andras Szekacs, Tamas Komives
      Pages: 4 - 12
      Abstract: This Opinion paper briefly summarizes the views of the authors on the directions of research in the area of plant protection chemistry. We believe these directions need to focus on (1) the discovery of new pesticide active ingredients, and (2) the protection of human health and the environment. Research revenues are discussed thematically in topics of target site identification, pesticide discovery, environmental aspects, as well as keeping track with the international trends. The most fundamental approach, target site identification, covers both computer-aided molecular design and research on biochemical mechanisms. The discovery of various classes of pesticides is reviewed including classes that hold promise to date, as well as up-to-date methods of innovation, e.g. utilization of plant metabolomics in identification of novel target sites of biological activity. Environmental and ecological aspects represent a component of increasing importance in pesticide development by emphasizing the need to improve methods of environmental analysis and assess ecotoxicological side-effects, but also set new directions for future research. Last, but not least, pesticide chemistry and biochemistry constitute an integral part in the assessment of related fields of plant protection, e.g. agricultural biotechnology, therefore, issues of pesticide chemistry related to the development and cultivation of genetically modified crops are also discussed.

  • Increased glutathione S-transferase activity in 35S(CaMV)-Zmgstf4
           transgenic Arabidopsis thaliana

    • Authors: András Bittsánszky, Gábor Gyulai
      Pages: 13 - 16
      Abstract: Clones of 35S-Zmgstf4 transgenic Arabidopsis thaliana expressing the glutathione S-transferase F4 gene of Zea mays was tested for stress-inductive GST (glutathione S-transferase) activity following treatments with the heavy metals Zn (150 and 1500 μM), Cd (20 and 30 μM) and chloroacetanilide herbicide metolachlor (2000 μM). The overexpression of Zmgstf4 gene in Arabidopsis resulted in an extreme resistance to all treatments. The GST activity of the transgenic plants was almost the double compared to the wild type plant in the untreated samples. After Cd (20 and 30 μM), and Zn (150 and 1500 μM) exposure the stress response activity of GSTs increased in both wild type and transgenic plants, however with significantly higher levels in transgenic plants with the extreme level at 20 μM CdSO4 treatment (0.24 in transgenic and 0.13 in wild-type). To compare GST responsivity, Zn treatments was less inductive compared to Cd. Metolachlor (200 μM) was totally tolerated by transgenic plants, compared to wild type plants, which died in 11 days.
