The complete plastid genome (plastome) of Nakai, the sole member of genus , endemic to Korea, was determined in this study. The plastome of is 156,612 bp in length and is composed of a pair of 26,351 bp inverted repeat regions (IRa and IRb) separating large (LSC) and small (SSC) single-copy regions of 84,970 and 18,940 bp, respectively (NCBI acc. no. NC 016921). The plastome encodes 129 genes, of which 112 are unique, including 78 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. Seventeen genes contain one intron and the 3 gene has two introns. The second intron of P is absent in the plastome. The AT content of is 63% overall, and in the LSC, SSC, and IR regions is 65%, 69%, and 58%, respectively. A total of 63 simple sequence repeats (SSR) are distributed among the noncoding regions of the genome. Phylogenetic analysis of the combined 82-gene data set for 35 plastomes suggests that is sister to the clade.
本研究测定了韩国特有属的唯一成员中井的完整质体基因组（质体基因组）。中井的质体基因组长度为156,612 bp，由一对26,351 bp的反向重复区域（IRa和IRb）组成，分别将84,970 bp的大单拷贝区域（LSC）和18,940 bp的小单拷贝区域（SSC）分开（NCBI登录号NC 016921）。质体基因组编码129个基因，其中112个是独特的，包括78个蛋白质编码基因、30个tRNA基因和4个rRNA基因。17个基因含有一个内含子，3个基因有两个内含子。中井质体基因组中P的第二个内含子缺失。中井的总体AT含量为63%，在LSC、SSC和IR区域分别为65%、69%和58%。基因组的非编码区域共分布有63个简单序列重复（SSR）。对35个质体基因组的82个基因组合数据集进行系统发育分析表明，中井是分支的姐妹群。
