Abstract

Here, we report the complete chloroplast (cp) genome of the moss Myurella julacea (Schwägr.) Schimp. We found that the total length of the M. julacea complete cp genome was 124,457 base pairs (bp) long, comprising 82 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. The genome had a typical quadripartite structure, and consisted of a large single-copy region (LSC) of 86,607 bp, a small single-copy region (SSC) of 18,508 bp, and a pair of inverted repeats with a length of 9671 bp each. The base composition of the cp DNA was 26.0% A, 29.4% T, 24.5% C, and 20.1% G with an overall GC content of 44.6%. Phylogenetic analysis revealed that M. julacea clustered into a clade with other Hypnales groups with high bootstrap support. The complete cp genome presented here will provide useful information for phylogenetic and evolutionary studies of endangered Bryophyte species.

摘要

在这里，我们报告了青苔Myurella julacea（Schwägr。）Schimp的完整叶绿体（cp）基因组。我们发现，胡桃木完整cp基因组的总长度为124,457个碱基对（bp），包括82个蛋白质编码基因，36个tRNA基因和8个rRNA基因。该基因组具有典型的四分体结构，由一个86,607 bp的大单拷贝区域（LSC），一个18,508 bp的小单拷贝区域（SSC）和一对反向重复序列组成，每个长度为9671 bp 。cp DNA的碱基组成为26.0％A，29.4％T，24.5％C和20.1％G，总GC含量为44.6％。系统发育分析表明，M。julacea与其他具有高度自举支持的Hypnales团体聚为一体。此处介绍的完整cp基因组将为濒临灭绝的苔藓植物物种的系统发育和进化研究提供有用的信息。
