Data from: Legume phylogeny and classification in the 21st century: progress, prospects and lessons for other species-rich clades

The Leguminosae, the third-largest angiosperm family, has a global distribution and high ecological and economic importance. We examine how the legume systematic research community might join forces to produce a comprehensive phylogenetic estimate for the ca. 751 genera and ca. 19,500 species of legumes and then translate it into a phylogeny-based classification. We review the current state of knowledge of legume phylogeny and highlight where problems lie, for example in taxon sampling and phylogenetic resolution. We review approaches from bioinformatics and next-generation sequencing, which can facilitate the production of better phylogenetic estimates. Finally, we examine how morphology can be incorporated into legume phylogeny to address issues in comparative biology and classification. Our goal is to stimulate the research needed to improve our knowledge of legume phylogeny and evolution; the approaches that we discuss may also be relevant to other species-rich angiosperm clades.

豆科（Leguminosae）作为被子植物的第三大科，全域分布且兼具极高的生态与经济价值。本研究探讨豆科系统学研究共同体应如何协同发力，针对该类群约751属、约19500种构建全面的系统发育估测，并将其转化为基于系统发育的分类体系。我们梳理了当前豆科系统发育研究的认知现状，并点明了现存的问题，例如类群取样与系统发育分辨率方面的短板。我们综述了可助力构建更完善系统发育估测的生物信息学与下一代测序技术方案。最后，本研究探讨了如何将形态学数据整合至豆科系统发育研究中，以解决比较生物学与分类学领域的相关问题。本研究旨在推动完善豆科系统发育与演化认知所需的相关研究；文中所讨论的研究方法，同样适用于其他物种丰富的被子植物支系。
