COTTON BREEDING HAS MADE SIGNIFICANT STRIDES DUE TO THE RAPID ACCUMULATION OF UPLAND COTTON REFERENCE GENOMES, WHICH HAVE IDENTIFIED CRUCIAL GENOMIC REGIONS LINKED TO SUPERIOR FIBER QUALITY, ROBUST STRESS RESILIENCE, AND VALUABLE PIMA COTTON INTROGRESSIONS. HOWEVER, FULLY LEVERAGING THESE GENETIC INSIGHTS IN PRACTICAL BREEDING PIPELINES IS CHALLENGING DUE TO TWO PRIMARY GAPS: 1) LACK OF INTEGRATED AND STANDARDIZED GENOMIC RESOURCES: EXISTING GENETIC DATA IS OFTEN FRAGMENTED, HINDERING COMPREHENSIVE COMPARISONS ACROSS CULTIVARS, AND 2) ABSENCE OF USER-FRIENDLY TOOLS: BREEDERS LACK INTUITIVE PLATFORMS TO EXPLORE AND UTILIZE REGIONS OF INTEREST IDENTIFIED THROUGH GENETIC MAPPING STUDIES.THIS PROJECT AIMS TO SOLVE THOSE PROBLEMS BY CREATING A COMPREHENSIVE, WELL-ORGANIZED COLLECTION OF COTTON GENOMES, CALLED A PAN-GENOME--THAT BRINGS TOGETHER AND IMPROVES EXISTING GENOME DATA. THIS RESOURCE WILL HELP SCIENTISTS AND BREEDERS BETTER UNDERSTAND HOW COTTON VARIETIES DIFFER AT THE GENETIC LEVEL. WE WILL ALSO PINPOINT KEY GENETIC REGIONS LINKED TO TRAITS BREEDERS CARE ABOUT MOST. TO MAKE THIS WORK ACCESSIBLE AND USEFUL, WE WILL DEVELOP A USER-FRIENDLY ONLINE PLATFORM CALLED THE BREEDER RESOURCE HUB. THIS TOOL WILL ALLOW COTTON BREEDERS TO EASILY EXPLORE GENETIC REGIONS OF INTEREST, SHARE DATA, AND APPLY NEW DISCOVERIES TO SPEED UP THE DEVELOPMENT OF BETTER COTTON VARIETIES THROUGH BOTH TRADITIONAL AND MODERN BREEDING METHODS. ULTIMATELY, THIS RESEARCH CAN LEAD TO MORE SUSTAINABLE COTTON FARMING, STRONGER RURAL ECONOMIES, AND BETTER CONSUMER COTTON PRODUCTS, ALL WHILE HELPING AMERICAN AGRICULTURE REMAIN COMPETITIVE GLOBALLY.
