Meso-Papilionoideae

Uncommon card · No. 190924

Meso-Papilionoideae or 50-kb Inversion clade is a monophyletic clade of the flowering plant subfamily Faboideae (or Papilionoideae) that includes the majority of papilionoid legumes. It contains many agronomically important genera, including Arachis (peanut), Cicer (chickpea), Glycine (soybean), Medicago (alfalfa), Phaseolus (common bean), Trifolium (clover), Vicia (vetch), and Vigna (mung bean). This clade is circumscribed by the presence of a 50 kb inverted DNA sequence in the plastome of member species and is consistently resolved in molecular phylogenies. The name Meso-Papilionoideae was proposed for this clade by Wojciechowski (2013). Its original name, 50-kb Inversion clade is still in use and the clade is still frequently referred to by this name in publications, as well as the Angiosperm Phylogeny Website and NCBI taxonomy browser.
