关于陆生植物的基本关系，人们的意见分歧很大，没有得到具有统计学意义的系统发育树。在这里，我们报告的系统发育分析，使用51个基因从整个叶绿体基因组序列的20个代表性的绿色植物物种。的分析，使用翻译的氨基酸序列，表明，现存的苔藓（苔藓，地钱，金鱼藻）形成一个单系组具有较高的统计置信度和现存的苔藓可能是姐妹现存的维管植物，虽然单系维管植物的支持并不强。核苷酸水平的分析无法解决统计置信度的基础关系。利用氨基酸序列推断苔藓植物单系性具有良好的统计学基础，在统计学上未被其他数据集所拒绝。我们建议branite单系作为目前最好的假设。
Opinions on the basal relationship of land plants vary considerably and no phylogenetic tree with significant statistical support has been obtained. Here, we report phylogenetic analyses using 51 genes from the entire chloroplast genome sequences of 20 representative green plant species. The analyses, using translated amino acid sequences, indicated that extant bryophytes (mosses, liverworts, and hornworts) form a monophyletic group with high statistical confidence and that extant bryophytes are likely sisters to extant vascular plants, although the support for monophyletic vascular plants was not strong. Analyses at the nucleotide level could not resolve the basal relationship with statistical confidence. Bryophyte monophyly inferred using amino acid sequences has a good statistical foundation and is not rejected statistically by other data sets. We propose bryophyte monophyly as the currently best hypothesis.
