Résumé
Over 30% of the earth’s surface is arid, and most climate change models predict future increases in drought length and severity that will adversely affect plant life. Plants adapt to water deprivation in part by fostering root-associated microorganisms that enhance resistance to environmental stresses. The impact of water limitation on molecular communication and the interactions between plants and their associated microbes remains poorly understood. This project will utilize a combination of analytical chemistry, bioinformatics, genetic, and physiological approaches to investigate the mutually beneficial interaction between the root-colonizing bacterium, Pseudomonas synxantha, and wheat under arid conditions. The research will yield new insights into how plants in dry soils recruit, shape, and manipulate their associated microbes to mitigate drought stress. This project will train graduate students and a postdoctoral scholar that will be engaged in all aspects of the research. The analysis of bacterial metabolic pathways will be done by undergraduates via individual research projects and as a part of microbial genetics and ecology classes. The project team will participate in university programs and coordinate outreach activities aimed at recruiting underrepresented groups into the sciences and strengthening science education at the elementary through college levels. This research is crucial for exploitation of beneficial microbial communities to improve crop performance and complement plant breeding efforts
