| Abstract/Contents: | "Poa annua (annual bluegrass, 2n=28, AABB) is an allotetraploid grass species that outperforms its diploid progenitors in both diversity of morphologies and geographic range. On golf course putting greens, Poa annua's ability to produce seed under 3mm mowing height has contributed to its discordant reputations as both a noxious weed and a valued commodity. Despite an estimated $40 billion U.S. turfgrass industry, there have been limited successful efforts directed at managing Poa annua, either for or against, primarily due to its complex genetic and epigenetic versatility. Here we present the pseudomolecule-level genome assemblies of Poa annua and its diploid progenitors, Poa infirma,and Poa supina. BRAKER2 annotations of these species with Iso-Seq RNA-evidence yielded 72,034, 37,207, and 35,698 high-confidence proteins, respectively. Both the assemblies and the annotations for all species contained >90% conserved orthologs, corroborating their quality. We demonstrate that the parental diploid genomes accurately represent the A and B subgenomes of Poa annua and characterize genetic exchange between and within the subgenomes of Poa annua. We show that the bifurcating ecological niches of the parents is mirrored by genomic and structural mutations in their diploid genomes. The subgenomes of Poa annua bear strong resemblance to its progenitors, confirming its status as a neo-allotetraploid. We speculate that Poa annua's global proliferation is conferred through the union of two parental genomes with wide genetic distance for hybridization and contrasting ecological ranges. We hope to incorporate genomic and transcriptomic resources to aid in better targeting of Poa annua in turfgrass applications." |
