Project description:Growth in soil inoculated with plant growth promoting bacteria (PGPB) producing 1-aminocyclopropane-1-carboxylate |(ACC) deaminase or expressing of the corresponding acdS in transgenic lines reduces the decline in shoot length, shoot weight and photosynthetic capacity triggered by salt stress in Camelina sativa. Reducing the levels of stress ethylene decreases the expression of salt stress-responsive genes, specifically genes involved in development, senescence, chlorosis and leaf abscission that are highly induced by salt to the levels that may have a less negative effect on growth and productivity. Moderate expression of acdS under the promoter of the rolD promoter or growing plants in soil treated with the PGPB Pseudomonas migulae 8R6, were more effective in eliminating the expression of the genes involved in ethylene production and/or signaling than expression under the more active Cauliflower Mosaic Virus 35S promoter.

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:Transcriptome analysis of Arabidopsis colonized by a plant-growth promoting rhizobacterium reveals a general effect on disease resistance RNA transcript levels of Arabidopsis plants, infected by the rhizobacterium Pseudomonas thivervalensis (strain MLG45), and axenic control plants were compared using cDNA microarrays representing approximately 14 300 genes. The analysis revealed an increase of defence-related transcripts in the shoots of bacterized plants relative to control (axenic) plants. These modifications of transcript levels were confirmed by physiological experiments. Plants infected with P. thivervalensis were more resistant to subsequent infections by the virulent pathogen P. syringae pv. tomato (strain DC3000) than control plants. In addition, photosynthesis rates were repressed consistently with the reduced growth of plants colonized by P. thivervalensis. These results highlight the value of molecular phenotyping to predict physiological changes.

Project description:Strategies that promote functional organ growth with minimal adverse effects are the ultimate goal of regenerative medicine but no single approach is currently available for organ level repair. Here, using an evolutionary adapted in vivo infection model - Mycobacterium leprae, with host cell reprogramming ability and its natural animal host, the nine-banded armadillo (Dasypus novemcinctus) that harbor bacteria in the highly regenerative liver - we present an in vivo model for promoting adult liver growth at organ level without adverse effects. Experimentally infected armadillos harboring bacteria in the liver, but not infection-resistant or drug-treated animals, showed a significantly increased total liver: body weight ratio, indicative of bacterial-driven liver organ growth in living animals. The machine-learning approach revealed an increase in healthy liver lobule number with a proportionate expansion of the hepatocyte mass with integrating vasculature and biliary networks responsible for functional liver growth. Intriguingly, infected enlarged livers show intact microarchitecture but without evidence of hepatocellular damage, fibrosis/scarring or tumorigenesis. Reactivation of armadillo liver progenitor and developmental genes/proteins, as well as upregulation of growth-, metabolism- and differentiation-associated markers with minimal change in oncogenes or tumor suppressor genes, suggests that bacteria have adapted dynamic regenerative, homeostasis and reprogramming mechanisms to promote de novo organogenesis while maintaining tissue integrity and tumor preventive strategies for host-dependent bacterial propagation. Thus, our model may facilitate the unravelling of in vivo endogenous regenerative pathways that effectively re-engage liver organ growth, with broad implications.
