Abstract

The complete chloroplast genome sequence of rare and endangered Camellia pubipetala Y. Wan & S. Z. Huang (Theaceae) was mentioned in this research. By studying comparatively, we found that the C. pubipetala Y. Wan & S. Z. Huang chloroplast genome was 156,993 bp in length and composed of 86,590 bp LSC, 18,211 bp SSC, and two reverse repeating regions with 26,090 bp. The whole GC content was 37.33%. The genome encoded 116 functional genes, including 80 protein-coding genes, 32 tRNA genes, and 4 rRNA genes. In order to find the phylogenetic relationship of C. pubipetala Y. Wan & S. Z. Huang within Camellia genus, we reconstructed phylogenetic tree. The results indicate that C. pubipetala Y. Wan & S. Z. Huang was closely related to Camellia huana voucher and Camellia ptilosperma.

摘要

本研究中提到了珍稀濒危山茶(Camellia pubipetala Y. Wan & SZ Huang ( Theaceae ))的完整叶绿体基因组序列。通过对比研究，我们发现C. pubipetala Y. Wan & SZ Huang叶绿体基因组长度为156,993 bp，由86,590 bp的LSC、18,211 bp的SSC和两个26,090 bp的反向重复区组成。总GC含量为37.33%。基因组编码了116个功能基因，其中蛋白质编码基因80个，tRNA基因32个，rRNA基因4个。为了寻找C. pubipetala Y. Wan & SZ Huan g在山茶属中的系统发育关系，我们重建了系统发育树。结果表明，C. pubipetalaY. Wan & SZ Huang 与Camellia huana 凭证和Camellia ptilosperma密切相关。
