Genomic Analysis Reveals Genetic Diversity, Population Structure and Evolutionary Dynamics in Bluebunch wheatgrass (Pseudoroegneria species)
Bluebunch wheatgrass (BBWG: Pseudoroegneria species) is an outcrossing perennial grass of considerable ecological and agricultural importance due to its resilience in adverse environmental conditions. To gain a deeper understanding of the diversity, population structure, and genetic relationship within the Pseudoroegneria genus, we analyzed genomic variations of 145 genotypes representing seven species (P. spicata, P. tauri, P. geniculata, P. libanotica, P. strigosa, P. stipifolia, and P. cognata) from major global lineages, using genotyping-by-sequencing.
