  • Proteins and RNA sequences required for the transition of the t-Utp
           complex into the SSU processome
    • Authors: Gallagher J.
      Abstract: Ribosomes are synthesized by large ribonucleoprotein complexes cleaving and properly assembling highly structured rRNAs with ribosomal proteins. Transcription and processing of pre-rRNAs are linked by the transcription-Utp sub-complex (t-Utps), a sub-complex of the small subunit (SSU) processome and prompted the investigations for the requirements of t-Utp formation and transition into the SSU processome. The rDNA promoter, the first 44 nucleotides of the 5΄ETS, and active transcription by pol I were sufficient to recruit the t-Utps to the rDNA. Pol5, accessory factor, dissociated as t-Utps matured into the UtpA complex which permitted later recruitment of the UtpB, U3 snoRNP and the Mpp10 complex into the SSU processome. The t-Utp complex associated with short RNAs 121 and 138 nucleotides long transcribed from the 5΄ETS. These transcripts were not present when pol II transcribed the rDNA or in nondividing cells. Depletion of a t-Utp, but not of other SSU processome components led to decreased levels of the short transcripts. However, ectopic expression of the short transcripts slowed the growth of yeast with impaired rDNA transcription. These results provide insight into how transcription of the rRNA primes the assemble of t-Utp complex with the pre-rRNA into the UtpA complex and the later association of SSU processome components.

  • Genome-wide transcriptional response to altered levels of the Rpb7 subunit
           of RNA polymerase II identifies its role in DNA damage response in
           Schizosaccharomyces pombe
    • Authors: Kumar D; Sharma N.
      Abstract: Transcription of protein-coding genes is a highly regulated process. In eukaryotes, it involves cross-talk between the RNA polymerase II enzyme and different proteins of the transcriptional machinery. Twelve different subunits, Rpb1 to Rpb12, constitute RNA polymerase II. The sequence of the Rpb7 subunit is highly conserved across organisms. However, our knowledge and understanding of the role of Rpb7 in Schizosaccharomyces pombe is still limited. Therefore, in the present study we have studied the transcriptional response of S. pombe cells expressing reduced levels of rpb7+. Our global transcriptional analysis revealed that expression of genes belonging to different DNA repair pathways was downregulated by reduced rpb7+ expression. It was observed that survival of S. pombe cells expressing low rpb7+ levels was compromised under genotoxic stress conditions. Rpb7 also exhibited genetic interaction with genes of various DNA repair pathways. Furthermore, the growth sensitivity of S. pombe cells with low rpb7+ levels under DNA-damaging conditions was completely rescued by human Rpb7, indicating a functional conservation between these proteins. In summary, results from our whole-genome level gene expression analysis, as well as phenotypic and genetic experiments suggest a role for Rpb7 in DNA damage response in S. pombe.

  • Proteome response of two natural strains of Saccharomyces cerevisiae with
           divergent lignocellulosic inhibitor stress tolerance
    • Authors: de Witt R; Kroukamp H, Volschenk H.
      Abstract: Strains of Saccharomyces cerevisiae with improved tolerance to plant hydrolysates are of utmost importance for the cost-competitive production of value-added chemicals and fuels. However, engineering strategies are constrained by a lack of understanding of the yeast response to complex inhibitor mixtures. Natural S. cerevisiae isolates display niche-specific phenotypic and metabolic diversity, encoded in their DNA, which has evolved to overcome external stresses, utilise available resources and ultimately thrive in their challenging environments. Industrial and laboratory strains, however, lack these adaptations due to domestication. Natural strains can serve as a valuable resource to mitigate engineering constraints by studying the molecular mechanisms involved in phenotypic variance and instruct future industrial strain improvement to lignocellulosic hydrolysates. We, therefore, investigated the proteomic changes between two natural S. cerevisiae isolates when exposed to a lignocellulosic inhibitor mixture. Comparative shotgun proteomics revealed that isolates respond by regulating a similar core set of proteins in response to inhibitor stress. Furthermore, superior tolerance was linked to NAD(P)/H and energy homeostasis, concurrent with inhibitor and reactive oxygen species detoxification processes. We present several candidate proteins within the redox homeostasis and energy management cellular processes as possible targets for future modification and study. Data are available via ProteomeXchange with identifier PXD010868.

  • Genetics is the logic of life (at least of mine)
    • Authors: Wickner R.
      Abstract: I retrace my path from math to medicine to biochemistry to yeast genetics, my focus on infectious diseases of yeast and finally prions. My discovery of yeast prions relied on my particular focus on the logical relations of non-chromosomal genetic elements and the chromosomal genes involved in their propagation and expression. Pursuing an understanding of yeast prions involved structural biology based on genetics, solid-state NMR, population genetics and more genetics.

  • Light exposure during growth increases riboflavin production, reactive
           oxygen species accumulation and DNA damage in Ashbya gossypii
           riboflavin-overproducing strains
    • Authors: Silva R; Aguiar T, Oliveira R, et al.
      Abstract: The overproduction of riboflavin (vitamin B2) by Ashbya gossypii, one of the most distinctive traits of this filamentous hemiascomycete, has been proposed to act as an ecological defense mechanism, since it is triggered by environmental stress. The interaction of endogenous riboflavin with light generates reactive oxygen species (ROS) and induces oxidative DNA damage in mammalian cells, but exogenous riboflavin was shown to protect A. gossypii spores against ultraviolet light. Envisioning a better understanding of this biotechnologically relevant trait, here we investigated the putative genotoxic effects associated with the overproduction of riboflavin by A. gossypii. For assessing that we developed the Ashbya Comet Assay, which was able to reproducibly measure oxidative (H2O2/menadione-mediated) and non-oxidative (camptothecin-mediated) DNA damage in A. gossypii. Using this protocol, we determined that exposure to sunlight-mimicking light during growth significantly increased the DNA damage accumulation in riboflavin-overproducing cells, but not in non-overproducing ones. The exposure of overproducing cells to light induced the intracellular accumulation of ROS and increased the production of riboflavin 1.5-fold. These results show that riboflavin-overproducing strains are highly susceptible to photo-induced oxidative DNA damage and draw attention for the importance of controlling the exposure to light of biotechnological riboflavin production processes with A. gossypii.

  • Astaxanthin enhances the longevity of Saccharomyces cerevisiae by
           decreasing oxidative stress and apoptosis
    • Authors: SJ S; Veerabhadrappa B, Subramaniyan S, et al.
      Abstract: The budding yeast, Saccharomyces cerevisiae, is an efficient model for studying oxidative stress, programmed cell death and aging. The present study was carried out to investigate antioxidant, the anti-apoptotic and anti-aging activity of a natural compound, astaxanthin, in S. cerevisiae model. The survivability of yeast antioxidant-deficient strains (sod1Δ, sod2Δ, cta1Δ, ctt1Δ and tsa1Δ) increased by 20%–40% when cells were pre-treated with astaxanthin, compared to hydrogen peroxide alone, as demonstrated in spot and colony forming unit assays. Reduced reactive oxygen species (ROS) levels, increased glutathione, decreased lipid peroxidation and induced superoxide dismutase activity in astaxanthin-treated cells indicate that astaxanthin protected the cells from oxidative-stress-induced cell death. In addition, astaxanthin protected anti-apoptotic-deficient strains (pep4Δ and fis1Δ) against acetic acid and hydrogen peroxide-induced cell death that suggests anti-apoptotic property of astaxanthin, and it was further confirmed by acridine orange/ethidium bromide, annexin V and 4',6-diamidino-2-phenylindole staining. The yeast chronological lifespan assay results showed that astaxanthin extends the lifespan of antioxidant-deficient strains by scavenging ROS, and anti-apoptotic-deficient mutants by protecting from apoptotic cell death compared to their respective untreated cells and wild type. Our results suggest that astaxanthin enhances the longevity of yeast S. cerevisiae by reducing oxidative stress and apoptosis.

  • PHO15 genes of Candida albicans and Candida parapsilosis encode HAD-type
           phosphatases dephosphorylating 2-phosphoglycolate
    • Authors: Kročová E; Neradová S, Kupcik R, et al.
      Abstract: Most of the phosphatases of human fungal pathogens Candida albicans and C. parapsilosis have never been experimentally characterised, although dephosphorylation reactions are central to many biological processes. PHO15 genes of these yeasts have been annotated as the sequences encoding 4-nitrophenyl phosphatase, on the basis of homology to PHO13 gene from the bakers’ yeast Saccharomyces cerevisiae. To examine the real function of these potential phosphatases from Candida spp., CaPho15p and CpPho15p were prepared using expression in Escherichia coli and characterised. They share the hallmark motifs of the haloacid dehalogenase superfamily, readily hydrolyse 4-nitrophenyl phosphate at pH 8–8.3 and require divalent cations (Mg2+, Mn2+ or Co2+) as cofactors. CaPho15p and CpPho15p did not dephosphorylate phosphopeptides, but rather hydrolysed molecules related to carbohydrate metabolism. The preferred substrate for the both phosphatases was 2-phosphoglycolate. Among the other molecules tested, CaPho15 showed preference for glyceraldehyde phosphate and ß-glycerol phosphate, while CpPho15 dephosphorylated mainly 1,3-dihydroxyacetone phosphate. This type of substrate specificity indicates that CaPho15 and CpPho15 may be a part of metabolic repair system of C. albicans and C. parapsilosis.

  • Geotrichum candidum gene expression and metabolite accumulation inside the
           cells reflect the strain oxidative stress sensitivity and ability to
           produce flavour compounds
    • Authors: Pracharova P; Lieben P, Pollet B, et al.
      Abstract: Geotrichum candidum is a fungus-like yeast widely used as a starter culture for cheese ripening for its proteolytic and lipolytic activities and its contribution to the cheese flavours. The sequenced strain G. candidum CLIB 918 was isolated from cheese Pont-L’Evêque. This strain's ability to produce volatile compounds was compared to the ability of a known strong sulphur compound producer G. candidum strain (Gc203). The aminotransferase-coding genes BAT2 and ARO8 were identified to be involved in methionine catabolism. The production of volatile compounds indicated that the sequenced strain was a moderate producer compared to the strong producer strain. The major volatile compounds were produced from sulphur amino acid, branched-chain amino acid and fatty acid metabolisms. Metabolite content of the cells showed that the ability of the strain to produce volatile compounds was inversely proportional to its ability to store amino acids inside the cells. Reduced glutathione, hypotaurine and taurine intracellular concentrations and volatile fatty aldehyde production indicated the role of oxidative stress sensitivity in flavour production. The increase in expression of several genes in a Reblochon-type cheese at the end of ripening confirmed that oxygen and iron were key factors regulating cheese flavour production.

  • A toolkit for rapid CRISPR-SpCas9 assisted construction of
           hexose-transport-deficient Saccharomyces cerevisiae strains
    • Authors: Wijsman M; Świat M, Marques W, et al.
      Abstract: Hexose transporter-deficient yeast strains are valuable testbeds for the study of sugar transport by native and heterologous transporters. In the popular Saccharomyces cerevisiae strain EBY.VW4000, deletion of 21 transporters completely abolished hexose transport. However, repeated use of the LoxP/Cre system in successive deletion rounds also resulted in major chromosomal rearrangements, gene loss and phenotypic changes. In the present study, CRISPR/SpCas9 was used to delete the 21 hexose transporters in an S. cerevisiae strain from the CEN.PK family in only three deletion rounds, using 11 unique guide RNAs. Even upon prolonged cultivation, the resulting strain IMX1812 (CRISPR-Hxt0) was unable to consume glucose, while its growth rate on maltose was the same as that of a strain equipped with a full set of hexose transporters. Karyotyping and whole-genome sequencing of the CRISPR-Hxt0 strain with Illumina and Oxford Nanopore technologies did not reveal chromosomal rearrangements or other unintended mutations besides a few SNPs. This study provides a new, ‘genetically unaltered’ hexose transporter-deficient strain and supplies a CRISPR toolkit for removing all hexose transporter genes from most S. cerevisiae laboratory strains in only three transformation rounds.

  • Engineering the architecture of erythritol-inducible promoters for
           regulated and enhanced gene expression in Yarrowia lipolytica
    • Authors: Park Y; Korpys P, Kubiak M, et al.
      Abstract: The non-conventional model yeast Yarrowia lipolytica is of increasing interest as a cell factory for producing recombinant proteins or biomolecules with biotechnological or pharmaceutical applications. To further develop the yeast's efficiency and construct inducible promoters, it is crucial to better understand and engineer promoter architecture. Four conserved cis-regulatory modules (CRMs) were identified via phylogenetic footprinting within the promoter regions of EYD1 and EYK1, two genes that have recently been shown to be involved in erythritol catabolism. Using CRM mutagenesis and hybrid promoter construction, we identified four upstream activation sequences (UASs) that are involved in promoter induction by erythritol. Using RedStarII fluorescence as a reporter, the strength of the promoters and the degree of erythritol-based inducibility were determined in two genetic backgrounds: the EYK1 wild type and the eyk1Δ mutant. We successfully developed inducible promoters with variable strengths, which ranged from 0.1 SFU/h to 457.5 SFU/h. Erythritol-based induction increased 2.2 to 32.3 fold in the EYK1 + wild type and 2.9 to 896.1 fold in the eyk1Δ mutant. This set of erythritol-inducible hybrid promoters could allow the modulation and fine-tuning of gene expression levels. These promoters have direct applications in protein production, metabolic engineering and synthetic biology.

  • Reassessment of requirements for anaerobic xylose fermentation by
           engineered, non-evolved Saccharomyces cerevisiae strains
    • Authors: Bracher J; Martinez-Rodriguez O, Dekker W, et al.
      Abstract: Expression of a heterologous xylose isomerase, deletion of the GRE3 aldose-reductase gene and overexpression of genes encoding xylulokinase (XKS1) and non-oxidative pentose-phosphate-pathway enzymes (RKI1, RPE1, TAL1, TKL1) enables aerobic growth of Saccharomyces cerevisiae on d-xylose. However, literature reports differ on whether anaerobic growth on d-xylose requires additional mutations. Here, CRISPR-Cas9-assisted reconstruction and physiological analysis confirmed an early report that this basic set of genetic modifications suffices to enable anaerobic growth on d-xylose in the CEN.PK genetic background. Strains that additionally carried overexpression cassettes for the transaldolase and transketolase paralogs NQM1 and TKL2 only exhibited anaerobic growth on d-xylose after a 7–10 day lag phase. This extended lag phase was eliminated by increasing inoculum concentrations from 0.02 to 0.2 g biomass L−1. Alternatively, a long lag phase could be prevented by sparging low-inoculum-density bioreactor cultures with a CO2/N2-mixture, thus mimicking initial CO2 concentrations in high-inoculum-density, nitrogen-sparged cultures, or by using l-aspartate instead of ammonium as nitrogen source. This study resolves apparent contradictions in the literature on the genetic interventions required for anaerobic growth of CEN.PK-derived strains on d-xylose. Additionally, it indicates the potential relevance of CO2 availability and anaplerotic carboxylation reactions for anaerobic growth of engineered S. cerevisiae strains on d-xylose.

  • Microbiology of high-sugar must fermentation by novel yeasts from the
           chihuahuan desert
    • Authors: Perrusquía-Luévano S; Cano-Herrera M, Guigón-López C, et al.
      Abstract: This work reports important results of aromatic profiles produced by native yeasts isolated from desert-grown wine grapes from the south of Chihuahua, México. These grapes stand very high temperatures during the ripening season, developing high sugar concentration and high pH. Yeast species found in grapes were identified by polymerase chain reaction and sequence analysis of the 5.8S internal transcribed spacer ribosomal RNA region. Aureobasidium namibiae, Sporobolomyces johnsonii, Candida apicola, Hanseniaspora uvarum, Candida thaimueangensis, Hanseniaspora opuntiae were identified. All of them can grow at glucose concentration of 35% (w/v) and 100 ppm of SO2, and produce low volatile acidity (0.2–1.0 g acetic acid/L). Volatile organic compounds analysis showed that C. thaimueangensis and one strain of C. apicola produce high levels of esters, and Hanseniaspora species produces high levels of higher alcohols and carbonyl compounds. The results of this study contribute to the knowledge about yeast communities associated with desert-grown winegrape yeasts.
