The complete chloroplast genome sequence of the Tertiary relict tree 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 and formed a well-supported monophyletic clade sister to genus in Ulmaceae.
本研究报道了第三纪残遗树种的完整叶绿体基因组序列。叶绿体基因组长度为158,875 bp，具有典型的被子植物定量结构，由一个大单拷贝（87,412 bp）和一个小单拷贝（18,683 bp）组成，二者被一对反向重复序列（26,390 bp）隔开。基因组注释显示共有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。基于整个质体基因组的系统发育分析表明，[物种名称1]和[物种名称2]在榆科中形成了一个得到充分支持的单系分支，是[属名]属的姐妹分支。
