维管束植物在大约 4.1 亿年前出现，然后分化成几个谱系，其中只有两个存活下来：真叶植物（蕨类植物和种子植物）和石松植物。我们在此报告了石松植物卷柏（Selaginella）的基因组序列，这是第一个报道的非种子维管植物基因组。通过比较进化多样化类群中的基因含量，我们发现从配子体主导的生命周期到孢子体主导的生命周期的转变比从非种子维管束到开花植物的转变所需的新基因少得多，而次生代谢基因在石松植物和被子植物谱系中广泛且平行地扩展。卷柏在转录后基因调控方面有所不同，包括重复元件的小RNA调控、tasiRNA途径的缺失以及细胞器基因的广泛RNA编辑。
Vascular plants appeared ~410 million years ago then diverged into several lineages of which only two survive: the euphyllophytes (ferns and seed plants) and the lycophytes. We report here the genome sequence of the lycophyte Selaginella moellendorffii (Selaginella), the first non-seed vascular plant genome reported. By comparing gene content in evolutionary diverse taxa, we found that the transition from a gametophyte- to sporophyte-dominated life cycle required far fewer new genes than the transition from a non-seed vascular to a flowering plant, while secondary metabolic genes expanded extensively and in parallel in the lycophyte and angiosperm lineages. Selaginella differs in post-transcriptional gene regulation, including small RNA regulation of repetitive elements, an absence of the tasiRNA pathway and extensive RNA editing of organellar genes.
