摘　　要：长尾毛蕊茶(Camellia caudata Wall.1832)是一种小型乔木,它主要分布于南亚。它富含抗氧化组分,是一种重要的药用植物。本文基于Illumina平台的双末端测序数据首次报道并描述了长尾毛蕊茶的叶绿体全基因组序列。完整的叶绿体基因组长度为157043 bp,由两个26095 bp长的反向重复序列(IRs)以及被其分开的86599 bp长的大单拷贝区(LSC)和18272 bp长的小单拷贝区(SSC)组成。该质体基因组包含了89个蛋白质编码基因、37个tRNA基因、8个rRNA基因和1个假基因(ycf 2)。质体基因组总GC含量为37.3%。基于20个相关物种全叶绿体基因组的系统发育分析表明,长尾毛蕊茶与同属的大果南山茶(C.semiserrata var.magnocarpa)和毛蕊红山茶(C.mairei)亲缘关系较近。Camellia caudata Wall.1832,a small tree,mainly distributes in South Asia.It is an important medicinal plant because of its high antioxidant contents.Here,for the first time,we report and characterize its complete chloroplast genome based on Illumina paired-end sequencing data.The complete chloroplast genome is 157043 bp in length,and contains two inverted repeats(IRs)of 26095 bp separated by a large single-copy(LSC)of 86599 bp and a small single copy(SSC)of 18272 bp.The plastome comprises 89 protein-coding genes,37 tRNA genes,8 rRNA genes and 1 processed pseudogene(ycf 2).The overall GC content of the plastome is 37.3%.Phylogenetic analysis based on 20 plastomes demonstrated that C.caudata is closely related to the congeneric C.semiserrata var.magnocarpa and C.mairei.
