Comprehensive analysis of the chloroplast genome and phylogenetic relationships of Sasa quelpaertensis Nakai.

Jeju-Joritdae ( Sasa quelpaertensis Nakai) is a broad-leaved bamboo grass endemic to Mount Halla, Jeju Island, South Korea. In this study, we report the complete chloroplast genome sequence of S. quelpaertensis . Its chloroplast genome is 139,730 bp in size and consists of a large single-copy (LSC, 83,351 bp) region, one small single-copy (SSC, 12,788 bp) region, and two inverted repeats (IRs, 21,796 bp each). The chloroplast genome of S. quelpaertensis encodes 131 genes, including 86 protein-coding, 37 tRNA, and 8 rRNA genes. The overall GC content of the S. quelpaertensis chloroplast genome is 38.86%. Phylogenetic analysis using the chloroplast genome sequence showed that S. quelpaertensis is closely related to Sasa veitchii and Sasella kogasensis . These findings provide valuable genomic resources for future studies of the Sasa genus in South Korea and other countries encompassing its distribution area.
