DNA sequence-based mapping and comparative genomics of theStgenome ofPseudoroegneria spicata(Pursh) Á. Löve versus wheat (Triticum aestivumL.) and barley (Hordeum vulgareL.)

Bluebunch wheatgrass (referred to as BBWG) [Pseudoroegneria spicata (Pursh) Á. Löve] is an important rangeland Triticeae grass used for forage, conservation, and restoration. This diploid has the basic St genome that occurs also in many polyploid Triticeae species, which serve as a gene reservoir for wheat improvement. Until now, the St genome in diploid species of Pseudoroegneria has not been mapped. Using a double-cross mapping populations, we...
