Objectifs
We aim to characterize the composition, diversity, and potential applications of the microbial assemblages that colonize crop-related plants in stressful environments ; to compare the microbiomes of focal crop plants with those of close, dryland-adapted relatives ; to translate these findings to crop plant enhancement ; to serve stakeholders, students, and junior scientists through engagement and mentorship ; to interface with relevant commodity groups and industry partners ; and to cultivate a broad collaborative network at the interface of microbiomes and crop improvement. Specifically, we aim to:1. Characterize the diverse and understudied microbiome of native and invasive arid-land plants in southern Arizona. Specifically, by synthesizing existing expertise in agricultural and wild settings, we will develop a comprehensive perspective on the structure and function of arid-land plant microbiomes. Focal research questions will include, but not be limited to : What microbial functions or groups are shared among drought-, salt-, and heat-adapted plants ? What microbial symbionts enable growth of wild relatives of crop plants in marginal lands ? What genomic traits of plants facilitate microbial enhancement ? What is the relationship of microbiome taxonomy and function to yield and quality in major crops for Arizona, the Southwest, and arid- and arid-transitioning lands worldwide ?2. Translate arid-land plant microbiomes for crop improvement in marginal, altered, and arid lands. Through innovative development of biodiversity informatics, genetic resources, microbial collections, and collaborations that leverage CALS infrastructure, we will test hypotheses regarding plant health and sustainability based on predictions from microbiome surveys and genomic analyses. Experiments will focus on enhancement of seed germination, drought tolerance, salt tolerance, and thermotolerance, carried out in field and controlled conditions3. Link microbiome characteristics to nutritional aspects of food plants through novel collaborations that will interface across CALS units, and develop related linkages with industry/growers groups, technology transfer, and as needed, patent protection4. Develop an infrastructure for intellectual and translational advancement of microbiome studies on campus and beyond, with the long-term goal of fostering research innovation, discovery, translational technologies, education, extension, outreach, and extramural funds
