摘要

Dipterocarpus retusus Blume 是世界自然保护联盟红色名录上的濒危物种。在这项研究中，我们报告了D. retus的完整叶绿体（cp）基因组（GenBank登录号：OP271853）。cp基因组长154,303 bp，其中大单拷贝（LSC）区长85,586 bp，小单拷贝（SSC）区长20,273 bp，被一对长24,222 bp的倒置重复序列（IR）隔开。它编码 128 个基因，包括 84 个蛋白质编码基因、36 个 tRNA 基因和 8 个核糖体 RNA 基因。我们还重建了Dipterocarpus的cp基因组系统发育，结果表明D. retusus与同域物种D. gracilis亲缘关系密切。这项研究可能会对Dipterocarpus属内部的系统发育关系提供有价值的信息。

Complete chloroplast genome of endangered species Dipterocarpus retusus Blume (Dipterocarpaceae) and its phylogenetic implications.

Dipterocarpus retusus Blume is an endangered species on the IUCN Red List. In this study, we reported the complete chloroplast (cp) genome of D. retusus (GenBank accession number: OP271853). The cp genome was 154,303 bp long, with a large single-copy (LSC) region of 85,586 bp and a small single-copy (SSC) region of 20,273 bp separated by a pair of inverted repeats (IRs) of 24,222 bp. It encodes 128 genes, including 84 protein-coding genes, 36 tRNA genes, and eight ribosomal RNA genes. We also reconstructed the cp genome phylogeny of Dipterocarpus, which indicated D. retusus was closely related with the sympatric species D. gracilis. This study may contribute valuable information to the phylogenetic relationships within the genus Dipterocarpus.
