The genome of Populus davidiana, a keystone aspen species, has been sequenced to improve our understanding of the evolutionary and functional genomics of the Populus genus. The Hi-C scaffolding genome assembly resulted in a 408.1 Mb genome with 19 pseudochromosomes. The BUSCO assessment revealed that 98.3% of the genome matched the embryophytes dataset. A total of 31,862 protein-coding sequences were predicted, of which 31,619 were functionally annotated. The assembled genome was composed of 44.9% transposable elements. These findings provide new knowledge about the characteristics of the P. davidiana genome and will facilitate comparative genomics and evolutionary research on the genus Populus.
杨属的模式种——山杨基因组已被测序，以增进我们对杨属进化和功能基因组学的理解。Hi-C 支架基因组组装得到了一个 408.1Mb 的基因组，包含 19 条假染色体。BUSCO 评估显示，基因组中有 98.3%与胚胎植物数据集相匹配。共预测到 31862 个蛋白质编码序列，其中 31619 个具有功能注释。组装的基因组由 44.9%的转座元件组成。这些发现提供了关于山杨基因组特征的新知识，并将促进杨属的比较基因组学和进化研究。
