Abstract

Bambusa beecheyana var. pubescens is mainly distributed in South China to Southwest China, growing on hillsides or river banks. In the current study, we sequenced the complete chloroplast genome of B.beecheyana var. pubescens and reported for the first time. The genome is 139,402 bp in total length, include a large single-copy (LSC) region of 82,936 bp, small single-copy (SSC) region of 12,868 bp, a pair of invert repeats (IR) regions of 21,799 bp. Plastid genome contains 132 genes, 85 protein-coding genes, 39 tRNA genes, and 8 rRNA genes. Phylogenetic analysis based on 25 chloroplast genomes indicates that B. beecheyana var. pubescens is closely related to Bambusa oldhamii, Bambusa ventricosa and Bambusa ventricosa multiplex in Bambusodae.

摘要

班布萨beecheyana var 。pubescens主要分布在华南至西南地区，生长在山坡或河岸上。在当前的研究中，我们对B.beecheyana var的完整叶绿体基因组进行了测序。pubescens并首次报告。基因组总长度为139,402 bp，包括82,936 bp的大单拷贝（LSC）区，12,868 bp的小单拷贝（SSC）区，一对21,799 bp的反向重复（IR）区。质体基因组包含132个基因，85个蛋白质编码基因，39个tRNA基因和8个rRNA基因。基于25个叶绿体基因组的系统发育分析表明，B. beecheyana var 。pubescens与Bambusa oldhamii关系密切，在班布苏达（Bambusodae）中重现了Bambusa ventricosa和Bambusa ventricosa。
