The complete plastome sequence of L. (Malvaceae) is determined in this study (NCBI acc. no. MG138151). is an important fruit crop in Southeastern Asia and known as the 'king of fruit'. Our plastome is the first reported sequences from the subfamily Helicteroideae of Malvaceae. The plastome sequence of is 163,974 bp in length and it is composed of a pair of 23,679 bp inverted repeat regions separated by large and small single-copy regions of 95,704 bp and 20,912 bp, respectively. The gene order and structure of the are similar to those of the typical plastome of land plants. The plastome encodes 113 genes, of which 79 are protein-coding genes, 30 are tRNA genes, and four are rRNA genes. Fifteen genes contain single intron and two genes have two introns. A total of 144 simple sequence repeats (SSR) were identified in the genome. Phylogenetic analysis show that (Helicteroideae) is sister group of (Tilioideae) clade with 100% bootstrap support.
本研究确定了锦葵科扁担杆属植物的完整质体基因组序列（NCBI登录号：MG138151）。扁担杆是东南亚一种重要的水果作物，被誉为“水果之王”。我们的扁担杆质体基因组是锦葵科扁担杆亚科首次报道的序列。扁担杆质体基因组长度为163,974 bp，由一对23,679 bp的反向重复区域组成，分别被95,704 bp的大单拷贝区域和20,912 bp的小单拷贝区域隔开。扁担杆的基因顺序和结构与陆地植物典型质体基因组的相似。该质体基因组编码113个基因，其中79个为蛋白质编码基因，30个为tRNA基因，4个为rRNA基因。15个基因含有单个内含子，2个基因有两个内含子。基因组中总共鉴定出144个简单序列重复（SSR）。系统发育分析表明，扁担杆亚科与椴树亚科分支是姐妹群，自展支持率为100%。
