Abstract

Caryota obtusa is an endangered and economically important species of the Arecaceae. The complete chloroplast genome sequence of this species is a circular molecule of 159,882 bp in size, including a pair of inverted repeats with length of 27,271 bp, separated by a large single-copy (87,645 bp) region and a small single-copy region (17,695 bp). In total, there are 131 genes, encoding 79 protein-coding genes, 40 tRNAs, and 10 rRNA genes, in which 123 genes, 69 CDSs, 37 tRNAs, and 10 rRNAs are unique, respectively. Phylogenetic inference confirmed the monophyly of the Caryota genus and its delimitation in subfamily Coryphoideae.

摘要

Caryota obtusa是槟榔科的一种濒临灭绝和经济上重要的物种。该物种的完整叶绿体基因组序列是一个大小为159,882 bp的环状分子，包括一对长度为27,271 bp的反向重复序列，由大的单拷贝区域（87,645 bp）和小的单拷贝区域（ 17,695 bp）。共有131个基因，分别编码79个蛋白质编码基因，40个tRNA和10个rRNA基因，其中123个基因，69个CDS，37个tRNA和10个rRNA是唯一的。系统发育推论证实了Caryota属的唯一性及其在鞘翅目亚科中的界定。
