Abstract

The genus was established based on the type species in 2006. The two species are distributed in Thailand and Laos; however, neither of them has been documented in China to date. During our field work in 2020, we collected a river-weed in Wuzhi Mountain, Hainan Province of China. After checking the morphological characters, it was identified as . Then, we assembled and annotated its chloroplast genome based on the genome skimming data. The results showed that the complete chloroplast genome was 133,748 bp with 35% GC content, consisting of 76 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. A maximum-likelihood tree constructed based on the k genes showed that WuMS109 was clustered with (AB537420, AB698348) without base difference and together with the remains of formed a sister clade to . This is the first report of that represents a new generic record for China. The discovery of this river-weed could lay the foundation for investigating their biogeographical patterns and species evolution in further studies.

摘要

该属基于模式种于2006年建立。这两个物种分布在泰国和老挝；然而，迄今为止在中国均未记录到它们。在我们2020年的野外工作中，我们在中国海南省五指山采集到一种水草。检查其形态特征后，它被鉴定为[具体物种名未给出]。然后，我们基于基因组浅层测序数据组装并注释了其叶绿体基因组。结果表明，完整的叶绿体基因组为133,748 bp，GC含量为35%，由76个蛋白质编码基因、30个tRNA基因和4个rRNA基因组成。基于[具体k个基因未给出]构建的最大似然树表明，WuMS109与[具体物种名未给出]（AB537420，AB698348）聚类且无碱基差异，并与[具体物种名未给出]的其余部分一起形成了[另一具体物种名未给出]的姐妹分支。这是[具体物种名未给出]的首次报道，代表了中国新的属级记录。这种水草的发现可为进一步研究其生物地理模式和物种进化奠定基础。
