This study presents the complete chloroplast genome of (154,121 bp, GC 39.2%), a newly recorded species in China, revealing a typical quadripartite structure: a large single-copy region (93,688 bp, GC 37.9%), a small single-copy region (18,929 bp, GC 33.9%), and two inverted repeats (20,752 bp each, GC 44.3%). The genome harbors 126 genes (82 protein-coding, 36 tRNA, 8 rRNA). Phylogenetic analysis groups with , differing from prior studies. These findings clarify its systematic position within and support its potential for coastal greening applications.
本研究展示了中国新记录物种（叶绿体基因组全长154,121 bp，GC含量39.2%）的完整叶绿体基因组，其呈现出典型的四分体结构：一个大单拷贝区域（93,688 bp，GC含量37.9%）、一个小单拷贝区域（18,929 bp，GC含量33.9%）以及两个反向重复序列（各20,752 bp，GC含量44.3%）。该基因组包含126个基因（82个蛋白质编码基因、36个tRNA、8个rRNA）。系统发育分析将其与[物种名]归为一类，这与之前的研究不同。这些发现明确了其在[属名]中的系统位置，并支持其在沿海绿化应用中的潜力。
