Abstract/Contents:"Both perennial ryegrass (Lolium perenne L.) and annual ryegrass (Lolium multiflorum L.) have turf and forage uses, and are high quality grasses in both spheres of utilization. Progress from genetic research has been slow in both species due to a lack of genomic resources that are necessary to accurately distinguish among target gene family members. To address this challenge, we have developed haplotype-level genome sequences from 'Manhattan' diploid perennial ryegrass and 'Gulf' diploid annual ryegrass. The assembled genome size of perennial ryegrass was 2.3Gb while that of annual ryegrass was 2.5Gb. Both genomes and transcriptomes had nearly complete gene coverage, with BUSCO scores over 96%. Re-sequencing the three main vernalization genes in these two species allowed us to find two Vrn1-like genes, three Vrn2-like genes, and a single FT/Vrn3 gene. Within each we have identified non-synonymous polymorphisms that may affect flowering response and timing in these two species."
