RESUMO
Sinopora hongkongensis is a critically endangered endemic tree species restricted to Hong Kong. Here we report its plastome sequence. The S. hongkongensis 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 S. hongkongensis in Lauraceae and explores relationships with other genera in the family.
