Chamaecrista fasciculata (partridge pea)

Overview

Chamaecrista fasciculata, an emerging legume model species, is a member of the Caesalpinieae / Mimosoideae clade. It has a widespread distribution over Eastern North America. Some of the characteristics that qualify it as a model plant are small plant size, short generation time, broad phenotypic diversity and a moderate size genome. Due to the unique phylogenetic position among legumes, the papilionoid polyploidy event is missing in Chamaecrista, which bestows a unique diploid genetics. Moreover among the caesalpinioid / mimosoid clade members, Chamaecrista is among the very few that nodulate.
