Abstract

We sequenced and assembled eight complete plastid genomes from three closely related pleurocarpous moss families: Amblystegium serpens, Campyliadelphus stellatus, Cratoneuron filicinum, Drepanocladus aduncus, and Leptodictyum humile (Amblystegiaceae), Calliergon sarmentosum and Warnstorfia exannulata (Calliergonaceae), and Calliergonella cuspidata (Pylaisiaceae). The newly generated plastid genomes range from 124,256 to 124,819 bp, with two inverted repeat regions (9,624–9,696 bp) separated by a large single-copy region (86,422–86,924 bp) and a small single-copy region (18,430–18,514 bp). All these plastid genomes encode 116 unique genes including 82 protein-coding genes, 30 tRNA genes and four rRNAgenes. The overall GC content is between 28.6%–29.3%. Phylogenetic analysis showed that all Amblystegiaceae species Amblystegium serpens, Campyliadelphus stellatus, Cratoneuron filicinum, Drepanocladus aduncus, Leptodictyum humile, and Sanionia uncinata clustered in one clade, which is sister to the Pylaisiaceae species Calliergonella cuspidata. The two Calliergonaceae species Calliergon sarmentosum and Warnstorfia exannulata form a clade and is sister to Amblystegiaceae and Pylaisiaceae.

摘要

我们测序和组装，从三个密切相关的青苔侧蒴家庭8分完整的质体基因组：柳叶藓，Campyliadelphus鲽，牛角藓，镰刀aduncus和Leptodictyum humile（Amblystegiaceae），Calliergon垂盆草和Warnstorfia exannulata（Calliergonaceae）和Calliergonella红豆杉（P科）。新生成的质体基因组范围为124,256至124,819 bp，其中两个反向重复区域（9,624–9,696 bp）被一个大的单拷贝区域（86,422–86,924 bp）和一个小的单拷贝区域（18,430–18,514 bp）隔开。所有这些质体基因组均编码116个独特基因，包括82个蛋白质编码基因，30个tRNA基因和4个rRNA基因。GC的总含量在28.6％–29.3％之间。系统发育分析表明，所有Amblystegiaceae种柳叶藓，Campyliadelphus鲽，牛角藓，镰刀aduncus，Leptodictyum humile和Sanionia uncinata在一个分支集群，这是姐姐给Pylaisiaceae种虎杖（Calliergonella cuspidata）。两个Calliergonaceae物种Calliergon sarmentosum和Warnstorfia exannulata形成分支，并且是Amblystegiaceae和Pylaisiaceae的姐妹。
