Abstract

Dioscorea polystachya 'Huilou' is a famous Chinese yam cultivar and cultivated in Shangqiu city of China. In this study, we sequenced, assembled, and analyzed the complete chloroplast (cp) genome of 'Huilou' yam. Our results showed that the complete cp genome of 'Huilou' yam is a typical tetrad structure with a total length of 153,234 bp and encoded 132 genes. Phylogenetic analysis strongly supported that 'Huilou' yam is closely related to D. polystachya 'Anping'. This study is highly significant for enriching the yam genetic resources and promoting yam breeding research.

“回楼”薯蓣属植物叶绿体全基因组及其系统发育分析。

会楼薯蓣是中国著名的山药品种，栽培于中国商丘市。在本研究中，我们对‘回楼’山药的叶绿体全基因组进行了测序、组装和分析。结果表明，‘回楼’山药cp全基因组为典型的四分体结构，全长153234 bp，编码132个基因。系统发育分析有力地支持了‘回楼’山药与‘安平’山药的亲缘关系。本研究对丰富山药遗传资源，促进山药育种研究具有重要意义。
