In this study, we determined the complete chloroplast genome of (Cycadaceae), one of the first-class protected plants in China. The chloroplast genome is 162,048 bp in length with 133 genes, including 87 protein-coding genes, eight ribosomal RNA genes, and 37 transfer RNA genes. The overall GC content is 39.4%. Phylogenomic analysis showed that as sister to all other species that with reported chloroplast genomes. The chloroplast genome of reported here will contribute to further comparative chloroplast genome of Cycads and helpful to study the phylogeography of Cycadaceae.
在本研究中，我们测定了中国一级保护植物之一苏铁科（Cycadaceae）的完整叶绿体基因组。该叶绿体基因组长度为162,048 bp，包含133个基因，其中包括87个蛋白质编码基因、8个核糖体RNA基因和37个转运RNA基因。总体GC含量为39.4%。系统基因组分析表明，该苏铁属植物与所有已报道叶绿体基因组的其他苏铁属物种互为姐妹群。本文报道的苏铁属植物叶绿体基因组将有助于进一步开展苏铁科叶绿体基因组的比较研究，并有助于研究苏铁科的系统地理学。
