Abstract

In this study, the chloroplast (Cp) genome of Zanthoxylum avicennae (Lam.) DC was sequenced by high-throughput sequencing technology. The length of the Cp genome of Zanthoxylum avicennae was 158,568 bp, and the total GC content was 38.4%, including a large single-copy (LSC) region of 86,318 bp, a small single-copy (SSC) region of 18,250 bp, and 27,000 bp of inverted repeats (IRs). The Cp genome encoded 131 genes, including 88 protein-coding, 37 tRNA, and six rRNA genes. Phylogenetic analysis of the genome sequence showed that Zanthoxylum avicennae was closely related to Zanthoxylum nitidum, Zanthoxylum esquirolii and Zanthoxylum motuoense of the Rutaceae family.

摘要

在这项研究中，通过高通量测序技术对Zanthoxylum avicennae (Lam.) DC 的叶绿体 (Cp) 基因组进行了测序。花椒Cp 基因组长度为 158,568 bp，总 GC 含量为 38.4%，包括一个 86,318 bp 的大单拷贝（LSC）区域，一个 18,250 bp 的小单拷贝（SSC）区域，以及27,000 bp 的反向重复 (IR)。Cp 基因组编码 131 个基因，包括 88 个蛋白质编码基因、37 个 tRNA 和 6 个 rRNA 基因。基因组序列的系统发育分析表明，花椒与芸香科花椒、花椒、花椒密切相关。
