利用叶绿体atpB、matK、ndhF、rbcL和线粒体matR基因序列，构建了中国维管植物的系统发育树。我们产生了一个矩阵，包括6098种，包括13 695个DNA序列，其中1803个是新产生的。我们的分类样本涵盖了中国维管植物323科3114属，覆盖了中国所有已知属的93%以上。综合性的大系统发育支持最近的石松植物、蕨类植物、裸子植物和被子植物的分子系统发育研究所确认的科之间和科内的大多数关系。对于被子植物，被子植物系统发育组IV中的大多数科被支持为单系，除了并系的龙脑香科和檀香科。几个大的科和单系的一些大属的下科关系是很好的支持我们密集的分类采样。我们的研究结果表明，两个种的Eberhardtia姐妹形成的分支，所有其他分类群的山葡萄科，除了肉籽。通过SoTree（http：//www.darwintree.cn/flora/index.shtml），我们已经使我们的中国维管植物系统学可用于创建子树，SoTree是生态学家的自动系统学组装工具。
We reconstructed a phylogenetic tree of Chinese vascular plants (Tracheophyta) using sequences of the chloroplast genes atpB, matK, ndhF, and rbcL and mitochondrial matR. We produced a matrix comprising 6098 species and including 13 695 DNA sequences, of which 1803 were newly generated. Our taxonomic sampling spanned 3114 genera representing 323 families of Chinese vascular plants, covering more than 93% of all genera known from China. The comprehensive large phylogeny supports most relationships among and within families recognized by recent molecular phylogenetic studies for lycophytes, ferns (monilophytes), gymnosperms, and angiosperms. For angiosperms, most families in Angiosperm Phylogeny Group IV are supported as monophyletic, except for a paraphyletic Dipterocarpaceae and Santalaceae. The infrafamilial relationships of several large families and monophyly of some large genera are well supported by our dense taxonomic sampling. Our results showed that two species of Eberhardtia are sister to a clade formed by all other taxa of Sapotaceae, except Sarcosperma. We have made our phylogeny of Chinese vascular plants publically available for the creation of subtrees via SoTree (http://www.darwintree.cn/flora/index.shtml), an automated phylogeny assembly tool for ecologists.
