Project description:Possitive effects of plant growth promoting bacteria (PGPB) inoculation on plant growth and development are dependent on interaction between bacterial strains and plant roots, which are usually the bacterial niche. Furthermore, phytohormones are key regulators of plant physiology. Ethylene is essential in plant growth and development and in response to drought. Plant sensibility to ethylene is involved in plant response to PGPB strain inoculation and plant growth promotion. We used microarrays to detail the global programme of gene expression underlying plant interaction with two different PGPB strains (isolated from arid soils in southern Spain) regarding to plant sentitivity to ethylene by tomato ethylene receptor 3 (SlETR3).
Project description:The objective of this work was to expand the knowledge about the possible mechanisms involved in the early stages of the interaction between the diazotrophic endophytic strain Kosakonia radicincitans UYSO10 and sugarcane plants. For that, a proteomic approach was conducted in the strain UYSO10 exposed or not to sugarcane exudates. Results showed that in the presence of root exudates the UYSO10 strain senses the environment and adapts its proteome to transport and metabolize different nutrients, and to interact with the host plant. These results deepen the knowledge of the potential mechanisms involved in the early stage of plant-bacteria endophyte interaction.
Project description:The aim of the project is to decipher the role of DNA methylation in the plant pathogenic bacteria Ralstonia solanacearum during host adaptation. As a first step, we present here the DNA methylation profile of the GMI1000 reference strain.
Project description:We report the first data of RNA sequencing of banana Musa acuminata cv. Pisang ambon kuning (AAA group) inoculated by two different endophyte bacteria named Stenothropomonas nitritireducens (BR-49) and Kocuria rhizophila (SL-08), respectively, prior to Fusarium oxysprorum f.sp. cubense tropical race 4 (Foc TR4).
Project description:This project is designed for whole transcriptome sequencing of bacteria isolated from Rhizosphere of Wheat Plant, which has its impact on overall plant growth.
Project description:To discover novel regulators that influence avermectin biosynthesis, comparative transcriptome analysis between wild-type strain ATCC31267 and avermectin overproducing strain 76-02-e were performed to reveal some differentially expressed genes.
Project description:Priestia endophytica FH5, which was isolated from healthy tomato rhizosphere soil, had biological activity against a variety of plant diseases, including R. solani. We isolated the chemicals generated by strain FH5 to better understand the interaction between strain FH5 and R. solani. A transcriptome study of strain FH5 with and without R. solani exposure was also performed. In response to the fungal pathogen R. solani, strain FH5 changed genes linked to amino acid transport, carbohydrate transport, energy generation and conversion, and inorganic ion transport and metabolism, according to our findings.
Project description:The aim of this experiment was to determine if the development of resistance to antibiotics can be driven by the concentration and speciation of Cu. Experimental setup was designed to investigate two hypotheses for which two strains of Gram- bacteria have been selected: - Do TE enhance AR in resistant bacteria? Resistant strain: Bioluminescent Pseudomonas aeruginosa PAO1 (Xen41, Tetracycline resistant) - Do TE induce AR in sensitive bacteria? Sensitive strain: Pseudomonas aeruginosa PAO1 (Wild Type)
