Septoria Tritici Blotch, caused by the hemibiotrophic fungus Zymoseptoria tritici, is one of the most severe diseases on wheat, responsible for yield losses up to 50%. Currently, strategies used to control this disease rely mainly on the use of chemical fungicides, and to a lower extent, on the use of partially resistant cultivars. Nevertheless, because of the pathogen resistances and an increasing social demand to reduce conventional pesticides in agriculture, new agroecological alternative crop protection methods, like biocontrol, must be developed. The main purpose of this thesis project was, therefore, to identify new effective biocontrol compounds on the wheat-Z. tritici pathosystem and to decipher their modes of action. An in vitro screening of a panel of 181 microbial compounds (fungal and bacterial extracts, rhamnolipids, lipopeptides…) was performed to assess their antifungal activity towards the pathogenic agent. The most active compounds were selected for further experiments, such as verifying their protection activity in planta. The ability of 19 rhamnolipids (RLs) to control the pathogen was explored and a structure-activity relationship study revealed that bioinspired RLs with ether or ester links and a 12 carbon hydrophobic fatty acid tail were the most effective for all tested biological activities (biocide activity, wheat defense elicitation and protection efficacy). Among them, Rh-Est-C12 was the most promising compound, with a protection efficacy of 78.9%. The potential of Rh-Est-C12 as well as mycosubtilin, a lipopeptide also effective to protect wheat against Z. tritici, to induce host defenses was investigated using a combined transcriptomic and metabolomic approach. The RL did not trigger any major disorganization of the wheat leaf physiology, hence it would protect the host mainly through its direct activity towards Z. tritici while mycosubtilin would display a dual mode of action, antifungal effect and wheat priming. Mycosubtilin could prime wheat by interacting with its plasma membranes leading to flavonoids accumulation and other abscisic acid dependent responses. New insights in wheat defense mechanisms towards Z. tritici were reported. Finally, two Bacillus velezensis strains, isolated from wheat phyllosphere, displayed promising antifungal effect towards the pathogenic agent. Characterization of their metabolites was performed and the putative role of bacillomycin D molecule family as a potent Z. tritici antifungal lipopeptide was highlighted

Wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) are among the main cereals cultivated worldwide due to their economic and social significance. However, their yield can drop by more than 40% when infected by the ascospore Zymoseptoria tritici, causing wheat septoria, and by Pyrenophora teres, which causes net blotch. Therefore, to reduce the use of pesticides, this project aimed to identify a strain that can significantly reduce the symptoms caused by these two pathogens. The strain Bacillus velezensis BE2 DSM115797 was chosen for its antifungal properties, both in vitro and in planta. An in-depth study of the mechanisms of action revealed that, when applied to the roots of wheat and barley, the bacterium significantly reduced leaf symptoms, inducing systemic resistance in the plant. Transcriptomic and metabolomic studies confirmed that the bacteria, once applied, did not trigger an immediate response in the plant. However, after a pathogenic infection, plants inoculated with the BE2 strain showed a more pronounced activation of their defense mechanisms, leading to a potentiating effect in the plant. At the bacterial level, a direct antagonism was also demonstrated with the identification of secondary metabolites that have antifungal effects on both fungi. Moreover, the production of these metabolites varied based on the presence of the pathogens

Grey mould disease caused by Botrytis cinerea is one of the most important diseases of the grapevine. The intensive use of the chemical products to irradicate the grey mould disease resulted in environmental pollution, and appearence of the resistant varieties of the pathogen. This study of research showed the antagonism between the B. Cinerea and the bacteria and yeast, and the different isolates of the genus Pythium. The selected antagonistic microbes to Botrytis cinerea, were identified using morphological as well as genetical tools and the study of their mode of action was initiated. The enzymatic activities and the elicitation capability were also studied. These activities have a direct relationship with the trigerring of the natural defence mechanisms of the grapevine. In the following context, the use of the selected micorobes as biocontrol agents can be undertaken for the effective control of Botrytis cinerea

Recombinant antibodies isolated from non-human primates represent very promising medical countermeasures against bioweapons. The advantages and methodological aspects of this approach have been described. An scFv, neutralizing the lethal toxin of Bacillus anthracis (2LF: KD= 1. 02 nM) and directed against the “lethal factor” subunit was isolated from a phage-displayed immune library, and characterised. Another scFv, 43RCA, neutralizing ricin, was obtained with the same methodology and tested (in particular: KD= 40 pM). This approach may also be used beyond bioweapons, as an scFv directed toward Aspergillus fumigatus was also isolated (MS130i-IIIC3: KD= 0,96 nM). On-line sequence analysis with IMGT tools allowed to show the high degree of similarity between these scFvs and their human counterparts. Antibody fragments were engineered, including an in vitro affinity maturation (KD initial = 3. 4 nM; KD final = 0. 18 nM). Utilizing IMGT standardisation and on-line tools, a “germline humanization” - utilizing FR derived from IgM, encountered by every Human, as opposed to IgG FR - was realized in order to ensure an optimal tolerance for one of our scFvs. A primatized IgG was tested in vivo and showed therapeutic and prophylactic capacities

To combat pests of crops (herbivores and pathogens) new pathways have been explored, in particular biological control. Used the nature and its organisms to regulate the populations of pathogens, that is the goal of the biological fight also called biocontrol. Among the organisms commonly found in biocontrol are micro-organisms, be they fungi or bacteria. These microorganisms have very interesting capabilities for farmers and agronomists. Indeed, studies have shown that they are able to interact with plants to allow a better growth and health of it.Then, in this thesis, we were interested in bacteria to find alternative methods of struggle with Fusarium graminearum, a pathogen of cereals responsible for high yield losses, especially thanks to the production of mycotoxins that will make the seeds unfit for human and animal consumption.Through an original approach of keeping noninhibitory strains in vitro for in planta tests, we have been able to show the limitations of in vitro selection. Thanks to the metabolic exploration of a particularly efficient strain, we have also been able to highlight potential new antifungal molecules. Through a model strain, we explored the mechanisms of the establishment of systemic resistance in wheat induced by bacteria. And finally, we have explored the potential of bacterial combinations in wheat protection that seems to represent a real future in the world of biocontrol.The work done is in line with the needs of new resources to limit the use of pesticides, but also in a need to better understand the tripartite interactions between wheat, pathogen and beneficial bacteria
