** AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** MICROORGANISMS ARE NEVER ALONE, CONSTANTLY COLLABORATING WITH OTHER SPECIES TO SURVIVE AND THRIVE IN THEIR ECOSYSTEMS. IN THIS CUTTING-EDGE PROJECT, WE WILL BE STUDYING THE COOPERATIVE RELATIONSHIP BETWEEN BACTERIA AND PATHOGENIC FUNGI, WITH A PARTICULAR FOCUS ON THE DEVASTATING FUSARIUM WILT PATHOGEN OF COTTON. THIS PATHOGEN POSES A SERIOUS THREAT TO THE PRODUCTION OF PIMA AND UPLAND COTTON, BUT IT CANNOT SURVIVE ON ITS OWN. IT RELIES ON A COMPLEX MICROBIAL COMMUNITY TO SUPPORT ITS GROWTH AND VIRULENCE, AND WE ARE GOING TO UNRAVEL THE MYSTERIES OF THIS COMMUNITY. BY CHARACTERIZING THE BACTERIAL MICROBIOME THAT ASSISTS THE PATHOGEN AND STUDYING THE GENES INVOLVED IN THESE INTERACTIONS, WE WILL GAIN A DEEP UNDERSTANDING OF HOW THIS DEADLY DISEASE OCCURS IN NATURE. WE WILL ALSO BE DEVELOPING METABOLIC MODELS TO SHED LIGHT ON THE INTRICATE BIOCHEMICAL PROCESSES THAT ENABLE THE PATHOGEN TO SURVIVE AND THRIVE. THIS RESEARCH HAS THE POTENTIAL TO REVOLUTIONIZE OUR UNDERSTANDING OF MICROBIAL ECOLOGY AND PAVE THE WAY FOR NEW STRATEGIES TO COMBAT DEVASTATING PLANT DISEASES.
