Full textOver the course of evolution, plants developed sophisticated defense mechanisms against bacterial and fungal pathogens. One of the first layers of plant defense is called PAMP triggered immunity (PTI) and is based on the recognition of conserved epitopes of pathogen-derived molecules called PAMPs/MAMPs (Pathogen/Microbe Associated Molecular Patterns). This recognition activates defense responses including the deposition of callose at the site of pathogen attack. Despite the fact that roots are the organs most subject to microbial interactions, MAMP signaling in roots remains largely unexplored. I developed an Arabidopsis thaliana seedling assay to study PTI in roots based on the detection of callose and the activation of promoter:GUS reporters of MAMP-responsive genes. I found that MAMPs trigger a strong response in roots dependent on ethylene signaling, the MYB51 transcription factor, the cytochrome P450 CYP81F2, and the PEN2 myrosinase, but independent of salicylic acid signaling. In addition, I show that the bacteria Pseudomonas syringae and Pseudomonas fluorescens suppress this response and that P. Syringae is doing so by producing the phytotoxi coronatine. I found that coronatine acts via the E3 ligase COI1 and the transcription factor JIN1/MYC2. I performed a forward genetic screen to isolate mutants impaired in COR-mediated suppression in an attempt to identify new players involved in COR signaling. In this thesis, I also present data concerning CYP76C2, a gene encoding a cytochrome P450 that is highly induced by MAMPs and pathogens in Arabidopsis leaves. I confirmed that CYP76C2 is activated during pathogen infection and various cell death elicited scenarios. Furthermore, I demonstrate that CYP76C2 is partially dependent on SA signaling and may be involved in controlling oxidative damage during infection

Full textPlants are continuously challenged by pathogens. Endoplasmic reticulum (ER) bodies are particular organelles, containing β-glucosidases, that form from the ER and play a major role in defense of the Brassicales. So far, most of the studies were conducted on the ER bodies from the shoots and a few information is available on ER bodies of the roots. In the present thesis work, we have focused on root cells of two brassicacea species, namely Arabidopsis thaliana and Raphanus sativus by using microscopical, biochemical and molecular biology techniques. First, we have investigated the occurrence and distribution of ER bodies in various cell types and found them abundantly present in all peripheral tissues. We have also found that the morphology and number of ER bodies differ from one cell type to another. Second, we have investigated the role of these organelles in root defense by studying the response of ER bodies to methyl jasmonate (MeJA), a phytohormone involved in plant defense signaling. The data show that MeJA induces a marked increase in the number of ER bodies along with an increase in β-glucosidase activity. Remarkably, MeJA also induces fusion of several ER bodies together resulting on the formation of very long organelles reaching 3-4 times the size of the normal ones. Third, we have studied the expression of 5 genes involved in ER body formation in the different root zones treated with MeJA and isolated by Laser Assisted Microdissection technique. The isolated root regions are the root cap zone, the meristematic zone, the elongation zone and the differentiation zone. Our findings show that the expression of the genes is fine-tuned in the different zones, under MeJA treated and standard conditions. This suggests that the formation of ER bodies is specifically regulated in different root tissues possibly in relation with the functional properties of each cell type in root development and defense

Full textPlants are surrounded by a diverse range of microorganisms that can cause serious crop losses and requires the use of pesticides. Flax is a major crop in Normandy and is regularly challenged by the pathogenic fungus Fusarium oxysporum (Fo) f. Sp. Lini. In order to protect themselves, plants use “innate immunity” called M/PTI (Microbe/Pathogen-Associated Molecular Patterns Triggered Immunity) as a first defense line against pathogens. Plants are able to perceive pathogens by the recognition of conserved motifs on the surface of the pathogens (M/PAMPs), by transmembrane protein receptors (PRRs, Pattern Recognition Receptors). The use of elicitors able to mimic M/PAMPs and activate plant defense may be an alternative for plant protection that could minimize the use of pesticides. Based on this, previous work was conducted by screening a chemical library of 1600 compounds and has allowed the identification of five compounds able to activate defense responses in Arabidopsis thaliana. During my PhD thesis, we tested those five compounds on their abilities to improve resistance of two commercially available flax varieties used for their fibers against F. Oxysporum, responsible of the vascular wilt. The data show that two of them, holaphyllamine (HPA) a natural compound and M4 a synthetic one, did not affect flax growth up to 10 μM. In addition, they did not have any negative effects on F. Oxysporum development and spores germination at the tested concentrations (up to 10 μM). Cell imaging analyses showed that HPA and M4 at 1 μM can induce oxidative burst as well as callose deposition in flax, a well-known marker of PAMP-elicited defense mechanisms. Furthermore, transcriptomic analyses showed that HPA and M4 induced changes in the expression patterns of two pathogenesisrelated (PR) genes (PR-2 and PR-3) coding for a β-(1,3)-glucanase and an endo-chitinase, respectively. These enzymes can degrade the fungal cell wall and stop its growth. Finally, flax plants pre-treated with HPA and M4 before infection with Fo f. Sp. Lini exhibited a decrease in the foliar disease symptoms by more than 50 % and 70 %, respectively. Together, these findings demonstrate that HPA and M4 are elicitors as they are able to activate defense responses in flax plants that lead to improving its resistance against Fo infection

Full textMembrane lipid catabolism is regulated in response to several stresses. Enzymes responsible for lipid hydrolysis are named lipid acyl hydrolases (LAH). An important role anticipated for such enzymes is to be involved in antimicrobial resistance and to provide precursors for the biosynthesis of oxylipins that are regulatory fatty acid derivatives. Exploration of the Arabidopsis thaliana genome has revealed the existence of numerous structural families of potential LAH genes, with members being upregulated in response to biotic stress. We have given priority to the functional study of Arabidopsis LAH related to patatin. This family comprises 9 members, two of which (AtPLP2 and AtPLP7) being strongly upregulated in leaves challenged with pathogens. AtPLP2 protein accumulation in response to the fungus Botrytis cinerea or Pseudomonas syringae bacteria is dependent on jasmonic acid and ethylene signaling. Expression of a AtPLP2-GFP fusion and biochemical analysis of recombinant AtPLP2 indicates that AtPLP2 encodes a cytoplasmic LAH. Transgenic plants with altered levels of AtPLP2 protein were generated and assayed for pathogen resistance. Unexpectedly, AtPLP2 expression increases B. Cinerea colonization and susceptibility to avirulent bacteria whereas silenced plants displayed enhanced resistance. Collectively, the data indicate that AtPLP2-encoded lipolytic activity is recruited by pathogens with different lifestyles to facilitate host colonization. Particularly, AtPLP2 potentiates plant cell death upon infection by B. Cinerea and reduces the efficiency of the hypersensitive response known to normally restrict avirulent bacteria multiplication. This global Arabidopsis LAH study opened some perspectives in identifying several candidates genes for detailed functional studies. Tools like numerous LAH knock-out mutants obtained will be the basis of our future work to decipher fatty acid mobilisation processes during plant defense responses

Full textThe hypersensitive response (HR) is one of the most efficient plant defense mechanisms against pathogens. Phenotypically, the HR corresponds to the lesions developing at the infection sites. In the narrow zone surrounding the cells undergoing the HR cell death, a strong activation of defense responses occurs contributing to a local, highly inhospitable environment for the invading pathogen. This latter phenomenon was called localized acquired resistance (LAR). It corresponds to the living component of the HR. Whereas the HR is induced by exogenous signals issuing from the pathogen, LAR is triggerred by endogenous signals issuing from the plant cells undergoing the HR. Consequently, the genes inducing LAR, whose none are known yet, should be characterized by a HR-specific expression profile. The first part of this work consisted in the set-up of a strategy aimed to isolated such latter genes. A screening by Differential Display Reverse Transcript Polymerase Chain Reaction allowed to isolate 24 ESTs (expressed sequence tag) with such an expression profile. A second part of the work consisted in the functional characterization, by loss- and gain-of-function experiements, of 3 genes issuing from that screen. Among the three genes, silencing by Virus-Induced Gene Silencing of NtRING1, encoding a putative E3 ligase with a RING-finger motive delays the HR in tobacco induced by ß-megaspemin, a well as the expression of different defense-related genes. Among the 5 genes issuing from the screen and so far analyzed at the fonctional level, NtRING1 and NtLRP1 appeared involved in the execution of the HR

Full textIn nitrogen-deficient conditions, legumes can establish a symbiosis with soil nitrogen-fixing bacteria (rhizobia) inside a new root organ, the nodule, where the rhizobia fix atmospheric nitrogen for the plant. Efficient symbiosis requires symbiotic nodule cells that host spectacular densities of nitrogen-fixing differentiated bacteria. Despite massive bacterial colonization, the symbiotic cells do not show apparent defense reactions, indicating that the nodule immune status is tightly controlled to allow the establishment and maintenance of the symbiotic partner. Among the identified legume genes involved in this process, MtSymbiotic CYSTEINE-RICH RECEPTOR-LIKE KINASE (MtSymCRK) contributes to the repression of the nodule immunity. MtSymCRK encodes a non-arginine-aspartate (non-RD) cysteine-rich receptor-like kinase belonging to the cysteine-rich kinase family of receptors involved in plant immunity. MtSymCRK is specifically expressed in nodule-infected cells after rhizobia internalization and prevents defense reactions. However, the signaling pathway by which MtSymCRK modulates the nodule immune response during symbiosis is not known. The PhD project aims to address how plant immunity is controlled in symbiotic nodules by deciphering the downstream MtSymCRK protein partners involved in the signaling pathway during chronic infection in Medicago littoralis. We identified an interacting partner of MtSymCRK using an original approach combining a high-throughput Yeast Two-Hybrid (Y2H) screen of an Arabidopsis thaliana (A. thaliana) open reading frames (ORFs) library and translational genetics towards Medicago truncatula (M. truncatula). Among seven A. thaliana identified proteins interacting with the kinase domain of MtSymCRK, AtGRF8 (GENERAL REGULATORY FACTOR 8) belonging to the 14-3-3 protein family has been selected as the most promising candidate. We searched for the closest homolog in M. truncatula, namely MtGRF8, and confirmed the interaction between the kinase domain of MtSymCRK and MtGRF8.To determine the role of MtGRF8 during symbiosis, we characterized Mtgrf8, a Medicago littoralis Tnt1 insertion mutant line. We showed that Mtgrf8 exhibits a symbiotic dysfunctioning characterized by defense and senescence responses that compromises the intracellular survival of the rhizobia in nodules. Finally, based on the hypothesis that some 14-3-3 and MtSymCRK regulate immunity and ethylene production. we also initiated the search for MtGRF8-interacting proteins by using a Y2H assay. Taken together, this work contributes to decipher the MtSymCRK signalling pathway during chronic infection

Full textPathogen attacks are perceived in Arabidopsis thaliana through recognition of pathogen- or microbe- associated molecular patterns (PAMPs/MAMPs). Although the study of various elicitors has revealed significant overlaps in defense response, the degrees of similarity/difference between MAMPs are not well defined. Oligogalacturonides (OGs), plant cell wall-derived elicitors, induce a wide range of defenses responses. Transcript profiling of Arabidopsis seedlings treated with OGs indicates that the response to OGs involves a transient response in the regulation of many genes. Among the genes, two cytochrome P450s, CYP81F2 and CYP82C3, are significantly induced shortly after OGs treatment. Monitoring the expression of these genes in a variety of defense-related mutants suggests that their rapid induction, mediated by OGs is independent of SA, JA, or Et signaling pathways. These reporter genes are also highly expressed in response to other MAMPs, including lipopolysaccharide (LPS), flagellin (Flg22), or chitin. Additional transcriptional analysis was carried out with OGs and pathogensynthesized flagellin (Flg22), two very different elicitors. Both triggered a fast and transient response that are similar. This response is characterized by activation of the early stages of multiple defense signaling pathways, particularly JA-associated processes. However, the response to Flg22 is stronger in the number of genes differentially expressed and the amplitude of change. The magnitude of genes induction was in both cases dose-dependent, but, even at very high concentrations, OGs did not induce as many genes as Flg22. Moreover, activation of senescence processes, SA-dependent secretory pathway genes, and PR1 expression was only observed with Flg22 elicitation. These results suggest a lower threshold for activation of early responses than for sustained late innate immune defenses. Induction of the Arabidopsis CYP81F2 gene is part of the early induced response to elicitors (OGs and Flg22). CYP81F2 gene expression is independent of the SA-, JAand Et-signaling pathways. CYP81F2 seems to catalyze the 4 methoxylation of indolic glucosinolates, which is required for callose formation in response to Flg22

Full textMyxococcus xanthus, a gram negative bacterium, secretes in culture media a thermostable low-molecular-weight blood anticoagulant activity during vegetative growth. Other strains of myxobacteria also produce a thermostable blood anticoagulant activity. This production is not co-regulated by genes that control secretion of other extracellular components such as proteins and polysaccharides. The blood anticoagulant activity is purified by pseudoaffinity chromatography on histidyl-sepharose 4B, and appeared heterogeneous by electrophoretic analysis. By an immunological approach, with polyclonal antibodies it was demonstrated that different cellular fractions, in particular membranous fraction, react with antiserum. In addition it was shown that purified fractions of blood anticoagulant activity contain a part of lipopolysaccharide
