Abstract excerpt
Elymus sibiricus L., a member of the Triticeae tribe, is a grass widely used for forage and restoring degraded grasslands in the Qinghai-Tibetan Plateau (QTP) region. Here, we present a high-quality reference genome assembly of allotetraploid E. sibiricus, consisting of 14 pseudochromosomes. Our findings suggest that large-scale bursts of retrotransposon activity, especially by Gypsy elements and unclassified...
