Comparative analysis of brachy and turfgrass genomes
PI: Geunhwa Jung
Understanding of grass genome structure and evolution has been significantly advanced through comparative genomics. However, the genomes of most cool-season forage and turf grasses belonging to the Pooideae subfamily remain understudied. Brachypodium distachyon recently sequenced is suited as a model species for comparative genomics of the Pooideae spp. due to its close evolutionary relatedness. Creeping bentgrass (Agrostis stolonifera) is one of the important cool-season turfgrasses widely used on golf courses due to its low mowing tolerance and aggressive growth habit. Genome analysis of this recently domesticated polyploid creeping bentgrass can add to the understanding of the evolution and domestication of grasses. Insights from comparative genomics with brachy will be useful for genetic improvement of Agrostis spp. and provide a better understanding of the evolution of the Pooideae subfamily spp.
