Alysicarpus Necker ex Desvaux (Fabaceae, Desmodieae) consists of ~30 species that are distributed in tropical and subtropical regions of theworld. In India, the genus is represented by ca. 18 species, ofwhich seven are endemic. Sequences of the nuclear Internal transcribed spacer from38 accessions representing 16 Indian specieswere subjected to phylogenetic analyses. The ITS sequence data strongly support the monophyly of the genus Alysicarpus. Analyses revealed four major well-supported clades within Alysicarpus. Ancestral state reconstructions were done for two morphological characters, namely calyx length in relation to pod (macrocalyx and microcalyx) and pod surface ornamentation (transversely rugose and nonrugose). The present study is the first report on molecular systematics of Indian Alysicarpus.
链荚豆属(蝶形花科,山蚂蝗族)由约30个物种组成,分布于世界热带和亚热带地区。在印度,该属约有18个物种,其中7个为特有种。对代表16个印度物种的38份材料的核内转录间隔区序列进行了系统发育分析。ITS序列数据有力地支持了链荚豆属的单系性。分析揭示了链荚豆属内四个主要的、得到有力支持的分支。对两个形态特征进行了祖先状态重建,即萼片相对于荚果的长度(大萼片和小萼片)以及荚果表面纹饰(横向具皱纹和无皱纹)。本研究是关于印度链荚豆分子系统学的首次报道。
