is a critically endangered endemic tree species restricted to Hong Kong. Here we report its plastome sequence. The plastome was 158,612 bp in length, with a large single-copy (LSC) region of 89,405 bp and a small single-copy (SSC) region of 18,205 bp, separated by two inverted repeat (IR) regions of 25,498 bp. It contained 126 genes, including 89 coding genes, 29 tRNA genes, and 8 rRNA genes. The overall GC content was 39.0%, and 43.0%, 37.7%, and 34.0%, in the IRs, LSC, and SSC regions, respectively. A phylogenetic analysis combining a subset of Lauraceae plastomes with closely related outgroup families confirms the placement of in Lauraceae and explores relationships with other genera in the family.
是一种极度濒危的特有树种，仅存于香港。在此我们报告其质体基因组序列。该质体基因组长度为158,612 bp，有一个89,405 bp的大单拷贝（LSC）区域和一个18,205 bp的小单拷贝（SSC）区域，由两个25,498 bp的反向重复（IR）区域隔开。它包含126个基因，包括89个编码基因、29个tRNA基因和8个rRNA基因。总体GC含量为39.0%，在IR、LSC和SSC区域分别为43.0%、37.7%和34.0%。一项系统发育分析将樟科质体基因组的一个子集与亲缘关系较近的外类群科相结合，确认了其在樟科中的位置，并探索了与该科其他属的关系。
