The chloroplast genome of the tree fern has been completely sequenced. The genome is 166,151 bp in size and features a typical quadripartite structure with the large (LSC, 86,762 bp) and small single copy (SSC, 21,641 bp) regions separated by a pair of inverted repeats (IRs, 28,874 bp each). It encodes 133 genes including 91 protein-coding genes, 33 tRNA genes, eight rRNA genes, and one pseudogene. Maximum-likelihood tree indicates that is sister to . This work provides a solid molecular resource for surveying phylogeny and chloroplast genomics of ferns.
桫椤的叶绿体基因组已被完全测序。该基因组大小为166,151碱基对，具有典型的四分体结构，其中大单拷贝区（LSC，86,762碱基对）和小单拷贝区（SSC，21,641碱基对）被一对反向重复序列（IRs，各28,874碱基对）隔开。它编码133个基因，包括91个蛋白质编码基因、33个tRNA基因、8个rRNA基因和1个假基因。最大似然树表明，[此处可能缺失具体物种名称]是[此处可能缺失具体物种名称]的姐妹种。这项工作为研究蕨类植物的系统发育和叶绿体基因组学提供了坚实的分子资源。
