Webinar: Multiple genome assemblies reveal alien introgressions and alternative haplotypes in elite wheat cultivars

Outline

Wheat (Triticum sp.) is the most widely grown crop globally and accounts for ~20% of the protein and calories consumed in human diets. This presentation will summarize highly contiguous assemblies of multiple wheat lines from the 10+ Wheat Genomes Project, which complement the reference genome assembly of Chinese Spring. These new genome assemblies capture genetic diversity currently utilized in global wheat breeding programs, including structural rearrangements, alternative haplotypes, and introgressions from wheat’s wild relatives. These variations are part of complex breeding histories aimed to improve grain yield and quality, and resistance to biotic and abiotic stresses. These genome assemblies are a foundation to support functional gene discovery and breeding the next generation of modern wheat cultivars.
