var. is an endangered aquatic herb with extremely narrow distribution. In this study, we assembled the chloroplast genome of this species based on the second-generation high-throughput sequencing. The genome is 157,783 bp in length with a typical quadripartite structure including a large single-copy region (LSC) of 88,294 bp, a small single-copy region (SSC) of 49,379 bp, and a pair of inverted repeats (IRs) of 10,055 bp each. A total of 128 genes were annotated, including 83 protein-coding genes (PCG), 37 tRNA genes, and 8 rRNA genes. The phylogenetic tree shows that var. has a close relationship with the genus The chloroplast genome presented here provides a valuable resource to conserve this endangered species.
变种是一种分布极为狭窄的濒危水生草本植物。在本研究中,我们基于第二代高通量测序组装了该物种的叶绿体基因组。该基因组长度为157,783 bp,具有典型的四分体结构,包括一个88,294 bp的大单拷贝区域(LSC)、一个49,379 bp的小单拷贝区域(SSC)和一对各为10,055 bp的反向重复序列(IR)。总共注释了128个基因,包括83个蛋白质编码基因(PCG)、37个tRNA基因和8个rRNA基因。系统发育树显示变种与属有密切关系。这里呈现的叶绿体基因组为保护这种濒危物种提供了宝贵的资源。
