Lecomte, Solène. "Anaerobic respiration diversification in Agrobacterium fabrum C58." Thesis, Lyon, 2019. http://www.theses.fr/2019LYSE1231.
Full textAnaerobic respiration may be an essential trait in lifestyle, environment colonization and survival. Until now, the only confirmed anaerobic respiration in Agrobacterium spp. is denitrification. Interestingly, this pathway is unequally widespread among Agrobacteria. These observations led me to my hypothesis which is anaerobic respiration and notably denitrification could explain the coexistence of Agrobacteria and their distribution in specific niches in the rhizosphere. My thesis was undertaken to explore the anaerobic respiration strategies of Agrobacterium spp. and to relate them to niche adaptation. The objectives of my thesis were to (1) characterize all the genes involved in denitrification in A. fabrum C58 in vitro, (2) explore the genes of denitrification that are needed during maize root colonization and (3) discover new anaerobic respirations that occur during maize root colonization (Figure 16). Mutational analysis is the classic way to determine the involvement of a gene in specific pathway. However, this method implies an a priori view and solid knowledge on target genes and cannot be applied for every situation. We have to develop a more adapted method to identify essential genes involved in growth in specific anaerobic conditions. - Denitrification genes in A. fabrum C58 in vitro. To complete denitrification pathway in A. fabrum C58 and identify all the genes and regulators involved in the denitrification function, we adopted two strategies: Firstly, an a priori view to (1) identify the nitrate reductase involved in the first step of denitrification and (2) validate the role of a non-coding RNA in denitrification control. To do so, we constructed a mutant of napA of A. fabrum C58 and a mutant of the non-coding RNA NopR and we evaluated their growth and capacity to produce N2O under anoxic conditions. Secondly, to identify all the genes involved in denitrification, we constructed a mutant transposon library of C58 and tested its growth under denitrification conditions in vitro in the presence of either nitrate or nitrite. - Role of A. fabrum C58 denitrifying genes in the root colonization of maize. It is well known that Transposon-sequencing (Tn-Seq) is a very powerful method to determine genes required for bacterial growth in the presence of their host. To determine denitrifying genes involved in root colonization under anaerobic conditions, we used the library constructed in C58 and performed in planta assays. The mutant library was inoculated on maize plants grown on fertile-ground and cultured under flooded conditions miming anaerobic conditions. Sequencing the recovered A. fabrum C58 cells will evidence the genes involved in this anaerobically specific niche colonization. - Discovery of new anaerobic respiration pathways in A. fabrum C58. To discover new anaerobic respiration pathways, we set-up growth assays of C58 under anoxic conditions in the presence C and N sources as terminal electrons acceptors. Interestingly, by culturing WT and NapA-deficient strains in contact with maize root under anoxic conditions (Chapter 1), we showed growth of both strains, suggesting that root exudates serve as terminal electrons acceptors for anaerobic growth of C58. To determine which maize exuded compounds can serve as TEAs, primary metabolites were identified by HPLC and some were tested as TEAs under the set-up conditions

Full textThe use of plant growth promotion bacteria or biocontrol agents as agricultural inoculants is an important eco-friendly alternative to substitute, or at least supplement, the excessive use of fertilizers and pesticides. In this work, we evaluated the biocontrol potential and rhizosphere competence of three bacteria that had shown plant growth promotion (PGP) abilities: Bacillus mycoides B38V, Paenibacillus riograndensis SBR5 and Burkholderia sp. 89. All three bacteria presented great versatility in their substrate utilization, which could enable them to survive in a competitive rhizosphere environment. However, inconsistencies were observed in the greenhouse experiments, whereas their interesting abilities observed in vitro did not result in benefits to the plants. Strain 89 produces a stable metabolite with a wide range of antifungal activity. Genomic comparisons and multilocus sequence analysis revealed Burkholderia sp. 89 as a new species of the Burkholderia cepacia complex and we described it as B. catarinensis 89T. We sequenced its genome and analyzed it with the AntiSMASH tool. This in silico prediction revealed the presence of a nonribosomal peptide synthetase (NRPS) cluster, which is related to the production of the siderophore ornibactin. Moreover, a hybrid NRPS- polyketide synthetase cluster for the production of the antifungal cyclic glicolipopeptide burkholdin was also found. A genome mining combined with a bioassay-guided fractionation with further mass spectrometry analysis was applied for the purification of these compounds. This approach enabled us to purify and characterize two variants of the siderophore ornibactin, D and F (761 and 789 Da, respectively). Also, we could detect the variant ornibactin B (m/z= 733) and the quorum sensing molecules homoserine lactones C6-HSL, 3OH-C8-HSL and C8-HSL in the supernatant of B. catarinensis 89T. Mass spectrometry analysis showed the presence of a group of metabolites with the masses 1240, 1254, 1268, 1216, 1244 and 1272 Da, which are probably new variants of the antifungal metabolite burkoldin. Therefore, B. catarinensis 89T has a great biotechnological potential for the production of metabolites with pharmaceutical and agricultural applications for the biocontrol of phytopathogenic fungi.
