Chun is a rare and threatened species of the monotypic genus Chun in the subfamily Dialioideae of Leguminosae. The complete plastid genome of was sequenced for the first time which also represents the first complete plastid genome of the subfamily Dialioideae. The total length of this genome is 159,358 bp with a large single copy (LSC) region (88,507 bp), a small single copy (SSC) region (18,689 bp), and two inverted repeat regions (IRs, 26,081 bp). We recovered 128 functional genes, including 83 protein-coding genes, 37 tRNA genes and 8 rRNA genes. Phylogenetic analysis strongly supported a sister relationship between and the clade consisting of Caesalpinioideae and Papilionoideae.
椿是豆科云实亚科单型属椿属中一种珍稀且受威胁的物种。首次对其完整的质体基因组进行了测序，这也代表了云实亚科的首个完整质体基因组。该基因组全长159,358 bp，有一个大单拷贝（LSC）区域（88,507 bp）、一个小单拷贝（SSC）区域（18,689 bp）和两个反向重复区域（IRs，26,081 bp）。我们鉴定出128个功能基因，包括83个蛋白质编码基因、37个tRNA基因和8个rRNA基因。系统发育分析有力地支持了椿与由苏木亚科和蝶形花亚科组成的分支之间的姐妹关系。
