Book Synopsis Differing Roles of Natural Diversity and Phenotypic Plasticity in Quantitative Resistance by : Jason Adam Corwin
Download or read book Differing Roles of Natural Diversity and Phenotypic Plasticity in Quantitative Resistance written by Jason Adam Corwin and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The plant immune system is complicated network of components that must detect and respond to a large variety of plant pathogen species and virulence strategies. A plant species can rely on at least two strategies for host resistance, which include 1.) to evolve genotypes that contain a robust network of components that is resistant to a wide variety of virulence strategies, also known as phenotypic plasticity, or 2.) it can rely on the natural genetic variation with host populations to recombine allelic variants of these components to create more resistance genotypes. The primary goal of this dissertation is to explore the relative role contribution of phenotypic plastic and natural genetic variation in both the host and pathogen in the Arabidopsis/Botrytis pathosystem and explore the genetic architecture driving host resistance. Chapter 2 focuses on the relative contribution of phenotypic plasticity and genetic variation to a broad survey of virulence-associated phenotypes with the fungal pathogen Botrytis cinerea. Chapter 3 uses the natural genetic variation in the Arabidopsis host to identify the potential components associated with quantitative resistance to Botrytis. Lastly, Chapter 4 utilizes the natural genetic variation within Botrytis to explore its influence on the phenotypic variation of the host responses. These studies will hopefully be the basis for a large variety of future work focused on exploring the functional underpinnings of quantitative host/pathogen interactions.

Book Synopsis Plant ABC Transporters by : Markus Geisler
Download or read book Plant ABC Transporters written by Markus Geisler and published by Springer. This book was released on 2014-09-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the fascinating superfamily of plant ATP-binding cassette (ABC) transporters and their variety of transported substrates. It highlights their exciting biological functions, covering aspects ranging from cellular detoxification, through development, to symbiosis and defense. Moreover, it also includes a number of chapters that center on ABC transporters from non-Arabidopsis species. ABC proteins are ubiquitous, membrane-intrinsic transporters that catalyze the primary (ATP-dependent) movement of their substrates through biological membranes. Initially identified as an essential aspect of a vacuolar detoxification process, genetic work in the last decade has revealed an unexpectedly diverse variety of ABC transporter substrates, which include not only xenobiotic conjugates, but also heavy metals, lipids, terpenoids, lignols, alkaloids and organic acids. The discovery that members of the ABCB and ABCG family are involved in the movement of phytohormones has further sparked their exploration and provided a new understanding of the whole family. Accordingly, the trafficking, regulation and structure-function of ABCB-type auxin transporters are especially emphasized in this book.
Book Synopsis Genome Scale Analysis of Arabidopsis Thaliana Quantitative Disease Resistance to the Generalist Fungal Pathogen Sclerotinia Sclerotiorum by : Thomas Badet
Download or read book Genome Scale Analysis of Arabidopsis Thaliana Quantitative Disease Resistance to the Generalist Fungal Pathogen Sclerotinia Sclerotiorum written by Thomas Badet and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In nature, plant pathogen interactions are frequent but disease is not the most prevalent outcome. Indeed, plants evolved an efficient immune system able to face multiple pathogen attacks. Getting insights into plant microbe interactions at multiple levels will improve our understanding of how plants defend against pathogens and help building sustainable agronomy. Fungal plant pathogens are major threats to food security worldwide. Sclerotinia sclerotiorum is an Ascomycete generalist plant pathogen causing mold diseases on hundreds of plant species. There is no genetic source of complete plant resistance to this generalist pathogen known to date. Instead, natural plant populations show a continuum of resistance levels controlled by multiple genes, a phenotype designated as quantitative disease resistance (QDR). Little is known about the molecular mechanisms controlling the interaction between plants and S. sclerotiorum, and more generally which are the molecular bases underlying QDR in plants. My thesis project consisted in a first part in identifying molecular mechanisms underlying QDR to S. sclerotiorum in natural accessions of the model plant Arabidopsis thaliana. A Genome wide association study (GWAS) allowed me to associate genetic variation with disease resistance to S. sclerotiorum. The analysis pinpointed three genes in A. thaliana genome as putative candidates involved in QDR to S. sclerotiorum. I led the functional characterization of these genes and investigated natural diversity at these loci. The results revealed that a prolyl-oligopeptidase (POQR) and an actin-related protein complex member (ARPC4) are associated with QDR against S. sclerotiorum. The analysis of actin filament networks highlighted their role in response to S. sclerotiorum. Furthermore, I showed that POQR alleles evolved convergently in different plant lineages, suggesting that some QDR molecular mechanisms are conserved across plants. Among fungal parasites, some like S. sclerotiorum are able to infect multiple species while others are restricted to one or few hosts. In the second part of the project, I investigated the properties of S. sclerotiorum genome associated to its ability to infect hundreds of plant species. Theory predicts that generalism comes at a cost and may underlie important fitness trade-offs. At the genome level, some codons (nucleotide triplets) allow more efficient translation than their synonymous. Indeed, the genetic encoding of proteins is redundant with multiple codons specifying the same amino acid. The optimization of codon-usage is a mean to reduce the costs associated with protein production. I analysed codon-usage at the genome level in 45 fungal species to reveal that generalist parasites are highly codon optimized. Moreover, I showed that optimized codons are under purifying selection, suggesting that codon optimization is an adaptation to generalist parasitism in fungi.

Book Synopsis From Model System to Crops by : Mercedes Mae Schroeder
Download or read book From Model System to Crops written by Mercedes Mae Schroeder and published by . This book was released on 2018 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants are subject to attack by microbial pathogens. This research utilized four distinct plant-pathosystems combined with methods of phytopathology, molecular genetics and chemical biology to study mechanisms of plant immunity against microbial phytopathogens. Chemical biology is the use of small molecule compounds to study biological processes. A previous chemical screen identified 114 compounds, called synthetic elicitors, that activate innate immune responses in the model plant Arabidopsis thaliana (Arabidopsis). Here, experiments conducted with three synthetic elicitors were found to provide disease protection in one or more of the following plant-pathogen interactions: Solanum lycopersicum (tomato) and Pseudomonas syringae pathovar tomato (Pst), Vigna unguiculata (cowpea) and Fusarium oxysporum formae speciales tracheiphilum race 3 (Fot3) or Arabidopsis and Hyaloperonospora arabidopsidis (Hpa). The results of these studies demonstrated the potential power of synthetic elicitors as both tools for molecular/chemical biology research and for direct protection of agricultural crop plants. In addition to synthetic elicitor-applied research, innovative agar plate-based infection assays were developed to study defense responses in Arabidopsis against Macrophomina phaseolina (Mp). Dubbed as a "global destroyer of crops", the necrotrophic, soil-borne fungus Mp infects more than 500 plant species including many economically important crops. Plant defenses against this powerful pathogen are poorly understood. The novel model phyto-pathosystem was used to quantify Mp biomass growth in roots and to analyze shoot disease severity in different Arabidopsis genotypes, quantitatively assessing host factors affecting the outcome of Mp infections. By comparative profiling of host transcripts in roots of the wild type Arabidopsis accession Col-0, with and without Mp infection, expression changes were uncovered in hundreds of genes potentially contributing to Mp defense mechanisms or putative effector targeting schemes. The results established the Mp-Arabidopsis interaction as a useful model pathosystem, which allowed for application of the vast genomics-related resources of this versatile model plant to the systematic investigation of previously understudied host defenses against a major broad host-spectrum plant pathogen.

Book Synopsis Microarray Analysis Identifies Potential Genes Associated with Botrytis Cinerea and Hormonal Stresses by :
Download or read book Microarray Analysis Identifies Potential Genes Associated with Botrytis Cinerea and Hormonal Stresses written by and published by . This book was released on 2018 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biotic and abiotic stresses critically influence plant survival and growth; survival depends on the ability to correctly sense and react to their environment. Certain environmental stresses must be overcome through careful manipulation of internal levels, and of the resulting signaling cascades. Hormones signaling networks and the crosstalk among each respective hormone signaling pathway are principle for response mediation via transcriptional reprogramming or altered signaling pathways. The long-term objective is to determine how plants sense biotic stresses, and how hormone signaling networks control and direct plant responses to the fungal pathogen Botrytis cinerea. This research aims to identify commonly regulated genes in Arabidopsis thaliana that responses to both B. cinerea and four selected hormones to ultimately improve the understanding of biotic stress responses and resistance in plants. The specific aims were to: (1) identify regulated genes in response to B. cinerea infection, salicylic acid (SA), jasmonic acid (JA), ethylene (ET), and abscisic acid (ABA); and (2) determine common up-and down-regulated genes in response to B. cinerea infection and the photohormones in Arabidopsis> These goals were accomplished by analyzing publicly available microarray data of Arabidopsis differentially-expressed genes (DEGs) in response to B. cinerea, SA, methyl jasmonate (MeJA), 1-aminocyclopropane-1-carboxylic acid (ACC; the ET natural precursor), and ABA. This analysis of microarray data revealed 6.9% of genes were up-regulated and 5.3% of genes were down-regulated at 18 hours post-infection with B. cinerea. Between 6.1 – 7.2% of genes were induced upon individual treatments of SA, MeJA, ACC, or ABA, with 9% and 1.2% of genes identified as commonly up-regulated and down-regulated genes, respectively, for all hormone treatments and B. cinerea together. Of these DEGs, most belong to biological functional binding proteins (i.e. transcription factors) or proteins related to cellular transport. Arabidopsis expression profiling of defense regulated genes in response to B. cinerea and hormone stresses aims to improve the understanding of how plants cope with biotic stresses on the transcriptional level and will help identify potential up- and down-regulated genes involved in Arabidopsis defense against the pathogen. This study could lead to the introduction of novel defense genes into crops, or to utilize genes already present in the organism to subtly modify the hormonal signaling cascade in response to B. cinerea, improving these crops’ resistance to B. cinerea infections. Changes in hormone regulations through gene expression following exposure to B. cinerea would allow a marketable and responsible solution to improving crop resistance to B. cinereal.
Book Synopsis Decoding the Complexity of Natural Variation for Shoot Growth and Response to the Environment in Arabidopsis Thaliana by : Charlotte Trontin
Download or read book Decoding the Complexity of Natural Variation for Shoot Growth and Response to the Environment in Arabidopsis Thaliana written by Charlotte Trontin and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genotypes adapted to contrasting environments are expected to behave differently when placed in common controlled conditions, if their sensitivity to environmental cues or intrinsic growth behaviour are set to different thresholds, or are limited at distinct levels. This allows natural variation to be exploited as an unlimited source of new alleles or genes for the study of the genetic basis of quantitative trait variation. My doctoral work focuses on analysing natural variation for shoot growth and response to the environment in A. thaliana. Natural variation analyses aim at understanding how molecular genetic or epigenetic diversity controls phenotypic variation at different scales and times of plant development and under different environmental conditions, and how selection or demographic processes influence the frequency of those molecular variants in populations for them to get adapted to their local environment. As such, the analysis of A. thaliana natural variation can be addressed using a variety of approaches, from genetics and molecular methods to ecology and evolutionary questions. During my PhD, I got the chance to tackle several of those aspects through my contributions to three independent projects which have in common to exploit A. thaliana natural variation. The first one is the analysis of the pattern of polymorphism from a set of 102 A. thaliana accessions at the MOT1 gene coding for a molybdate transporter (an essential micronutrient) and responsible for contrasted growth and fitness among accessions in response to Mo availability in the soil. I showed at different geographical scales that MOT1 pattern of polymorphisms is not consistent with neutral evolution and shows signs of diversifying selection. This work helped reinforce the hypothesis that in some populations, mutations in MOT1 have been selected to face soils rich in Mo and potentially deleterious despite their negative effect on Mo-limiting soils. The second project consists in the characterisation and functional analysis of two putative receptor-like kinases (RLKs) identified from their effect on shoot growth specifically under mannitol-supplemented media and not in response to other osmotic constraints. The function of such RLKs in A. thaliana, which is not known to synthesize mannitol was intriguing at first but, through different experiments, we built the hypothesis that those RLKs could be activated by the mannitol produced by some pathogens such as fungi and participate to plant defensive response. The third project, in collaboration with Michel Vincentz's team from CBMEG (Brasil) and Vincent Colot (IBENS, Paris), consists in the analysis of the occurrence of natural epigenetic variants of the QQS gene in different populations from Central Asia and their possible phenotypic and adaptive consequences. Overall, these analyses of the genetic and epigenetic molecular variation leading to the biomass phenotype(s) in interaction with the environment provide clues as to how and where in the pathways adaptation is shaping natural variation.
