Villars, 1779 is a typical alpine sedge with both ecological and agricultural value. The work reported here is the first complete chloroplast genome of this species. The chloroplast genome, with a total size of 185,609 bp, consists of two inverted repeats (IRs, 38,374 bp) separated by a large single-copy (LSC, 99,911 bp) region, and a small single-copy (SSC, 8950 bp) region. The overall genome GC content is 34.12%. The genome contains 125 genes, consisting of 82 protein-coding genes, 35 tRNA genes, and eight rRNA genes. Phylogenetic analysis supports the taxonomic treatment of incorporating genus to a broader circumscription of . Our work could be helpful to future research on Cyperaceae.
1779年的维拉斯草是一种典型的高山莎草，具有生态和农业价值。本文报道的工作是该物种的首个完整叶绿体基因组。叶绿体基因组全长185,609 bp，由两个反向重复序列（IRs，38,374 bp）组成，中间被一个大单拷贝（LSC，99,911 bp）区域和一个小单拷贝（SSC，8950 bp）区域隔开。基因组的总体GC含量为34.12%。该基因组包含125个基因，包括82个蛋白质编码基因、35个tRNA基因和8个rRNA基因。系统发育分析支持将该属纳入更广泛的分类范围的分类处理。我们的工作可能有助于未来对莎草科的研究。
