RAB — Phaseolus vulgaris

Summary

PHAVU_008G231300, designated PvRAB (also known as PvRBE), encodes a C2H2-type zinc-finger transcription factor on chromosome 8 of French bean (Phaseolus vulgaris). The protein localises to the nucleus and has DNA-binding transcription factor activity. PvRAB is associated with the regulation of meristem organisation, DNA-templated transcription, cell division, vesicle transport, nodulation, and response to cold. Phenotypic associations link the gene to floral organogenesis, including altered sepal, petal, and stamen development, as well as organ separation, cytokinesis, cell geometry, hypocotyl growth, and cellulose biosynthesis. Studies of related genes in other species connect the family to petal size and morphology, floral organ development, organ identity, salt response, and directional cell growth.
