Abstract

Bonia amplexicaulis (L.C.Chia, H.L.Fung & Y.L.Yang) N.H.Xia is a member of the Bambusoideae subfamily in Poaceae. In this study, we sequenced, assembled and characterized the complete chloroplast genome of B. amplexicaulis. The complete chloroplast genome was 139,935 bp in size, including a large single copy region of 83,453 bp, a small single-copy region of 12,860 bp and a pair of reverse repeats of 21,811 bp in size. The annotation of the B. amplexicaulis chloroplast genome indicates that it contained 83 protein-coding genes, 36 tRNA genes and 8 rRNA genes. Our phylogenetic analysis of all protein-coding genes from the 36 complete chroloplast grass genomes using Cyperus rotundus as outgroup showed that B. amplexicaulis is closely related to Otatea glauca and Pariana campestris to form the Bambusoideae lineage of the grass family.

摘要

Bonia amplexicaulis (LCChia, HLFung & YLYang) NHXia 是禾本科竹亚科的成员。在这项研究中，我们对B. amplexicaulis的完整叶绿体基因组进行了测序、组装和表征。完整的叶绿体基因组大小为 139,935 bp，包括一个 83,453 bp 的大单拷贝区域、一个 12,860 bp 的小单拷贝区域和一对大小为 21,811 bp 的反向重复序列。B. amplexicaulis叶绿体基因组的注释表明它包含83个蛋白质编码基因、36个tRNA基因和8个rRNA基因。我们使用香附作为外群对来自 36 个完整叶绿体草基因组的所有蛋白质编码基因进行的系统发育分析表明B. amplexicaulis与Otatea glauca和Pariana campestris密切相关，形成草科的 Bambusoideae 谱系。
