Abstract

The complete chloroplast genome sequence of the Tertiary relict tree Zelkova serrata was reported in this study. The chloroplast genome is 158,875 bp in length with a typical angiosperm quantitative structure consisting of a large single copy (87,412 bp) and a small single copy (18,683 bp) separated by a pair of inverted repeat (26,390 bp). Genome annotation revealed a total of 129 genes comprising 84 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenomic analysis based on the whole plastomes indicated that Z. serrata and Z. schneideriana formed a well-supported monophyletic clade sister to genus Ulmus in Ulmaceae.

摘要

这项研究报道了第三级遗迹树Zelkova s​​errata的完整叶绿体基因组序列。叶绿体基因组的长度为158,875 bp，具有典型的被子植物定量结构，该结构由一个大的单拷贝（87,412 bp）和一个小的单拷贝（18,683 bp）组成，并由一对反向重复序列（26,390 bp）隔开。基因组注释揭示了总共129个基因，包括84个蛋白质编码基因，37个tRNA基因和8个rRNA基因。基于整个质体组的系统进化分析表明，锯齿状。和锯齿状Z在榆科中形成了榆树属的良好单亲进化姐妹。
