英文摘要 | Elymus species, belonging to Triticeae tribe, is a tertiary gene pool for improvement of major cereal crops. Elymus sibiricus, a tetraploid with StH genome, is a typical species in the genus Elymus, which is widely utilized as a high-quality perennial forage grass in template regions. In this study, we report the construction of a chromosome-scale reference assembly of E. sibiricus line Gaomu No. 1 based on PacBio HiFi reads and chromosome conformation capture. Subgenome St and H were well phased by assisting with kmer and subgenome-specific repetitive sequence. The total assembly size was 6.929 Gb with a contig N50 of 49.518 Mb. In total, 89,800 protein-coding genes were predicted. The repetitive sequences accounted for 82.49% of the genome in E. sibiricus. Comparative genome analysis confirmed a major species-specific 4H/6H reciprocal translocation in E. sibiricus. The E. sibiricus assembly will be much helpful to exploit genetic resource of StH species in genus Elymus, and provides an important tool for E. sibiricus domestication. |
