摘要
综述了石松类和蕨类植物系统发育的最新研究成果。目前研究表明传统的蕨类植物概念(包括石松类和真蕨类)需要修订,一个关于蕨类植物的分类系统也已经发表。中国的植物多样性很丰富,包括了世界上石松类和蕨类植物各个主要类群的代表。本文还利用rbcL基因序列(包括国产蕨类63科中的62科179属184种)构建了系统发育树。基于rbcL序列分析所获得的石松类和蕨类各主要类群间的系统演化关系同以往对各个特定类群开展的较为密集的类群取样和多性状分析(形态学+分子序列证据)的结果基本一致。在参考Smith等人系统的基础上,我们尝试性地对中国石松类和蕨类植物进行了科级水平上的系统发育重排。
Recent phylogenetic studies have revealed that the traditional concept ofpteridophytes which includes lycopods and ferns should be revised and a new classification of the extant monilophytes has just been published by Smith et al. China is very rich in plant diversity, with representatives of most important major groups of the lycophytes and monilophytes. Here we present the recent progress in phylogenetic analyses of lycophytes and monilophytes with a focus on relationships among the Chinese taxa. We conducted a phylogenetic analysis using sequence data of the chloroplast rbcL gene of 184 species （179 genera） representing 62 of a total of 63 families recognized by R. C. Ching. The relationships of all major lineages recovered in the rbcL phylogeny generally agree with those reconstructed in the studies that focused on these clades individually and had more extensive ingroup taxon sampling and/or character sampling. A tentative systematic arrangement focused on the Chinese lycophytes and monilophytes at the family level is presented.
