摘要

维管系统是植物生态学和进化的核心。本研究表明，豆科植物4个亚科27个属的100多个物种进化出异位形成层，这是一种不寻常的维管模式；这些物种出现在除南极洲以外的所有生物地理区域。由于豆科包括许多具有异位形成层的重要生态和经济物种，该科成为研究种子植物维管创新意义的理想系统。植物维管变异数据库，一个不断更新的资源，提出。

Vascular Diversity in Leguminosae: Evolutionary and Ecological Insights From a Globally Distributed Lineage

The vascular system is central to plant ecology and evolution. Here, we show that more than 100 species across 27 genera and four subfamilies of Leguminosae have evolved ectopic cambia, an unusual vascular pattern; these species occur in all biogeographical regions except Antarctica. Because Leguminosae includes many ecologically and economically important species with ectopic cambia, the family emerges as an ideal system for studying the implications of vascular innovation in seed plants. The Plant Vascular Variants Database, a continuously updated resource, is presented.

期刊介绍： Ranked by the ISI index, Biotropica is a highly regarded source of original research on the ecology, conservation and management of all tropical ecosystems, and on the evolution, behavior, and population biology of tropical organisms. Published on behalf of the Association of Tropical Biology and Conservation, the journal''s Special Issues and Special Sections quickly become indispensable references for researchers in the field. Biotropica publishes timely Papers, Reviews, Commentaries, and Insights. Commentaries generate thought-provoking ideas that frequently initiate fruitful debate and discussion, while Reviews provide authoritative and analytical overviews of topics of current conservation or ecological importance. The newly instituted category Insights replaces Short Communications.
