The complete plastid genome of C. Y. Wu was firstly reported. The full length of the plastid genome was 152,092 bp and comprised of a large single-copy (LSC) region of 84,090 bp, a small single-copy (SSC) region of 17,534 bp, and two inverted repeat regions (IRs) of 25,234 bp. A total of 131 genes were encoded, including 87 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. The overall GC content of the plastid genome was 38.3%. Further phylogenetic analysis based on 18 accessions inferred that the genus can be divided into two clades, and is evolutionarily close to . Our study provided essential genetic resources for further studies on the evolution and genetic diversity of the genus and its related taxa.
首次报道了吴征镒的完整质体基因组。质体基因组全长152,092 bp，由一个84,090 bp的大单拷贝（LSC）区域、一个17,534 bp的小单拷贝（SSC）区域和两个25,234 bp的反向重复区域（IRs）组成。共编码131个基因，包括87个蛋白质编码基因、36个tRNA基因和8个rRNA基因。质体基因组的总体GC含量为38.3%。基于18个样本的进一步系统发育分析推断，该属可分为两个分支，且在进化上与……接近。我们的研究为该属及其相关类群的进化和遗传多样性的进一步研究提供了重要的遗传资源。
