RAB — Phaseolus vulgaris

Summary

PHAVU_008G117300 (PvRAB) on chromosome 8 of French bean encodes a C2H2-type zinc-finger transcription factor with a plant development regulator domain. The gene is associated with DNA-binding transcription factor activity and localises to the nucleus. It has been linked to regulation of meristem organisation, vesicle transport, nodulation, cell division, response to cold, and regulation of transcription. Phenotype associations include cytokinesis, cell geometry, floral organogenesis, organ separation, hypocotyl growth, and cellulose biosynthesis, as well as specific floral defects such as reduced second-whorl organs, extra sepals, and altered petal development. Studies of related genes in other species link the family to petal size, petal morphology, floral organ development, salt response, organ identity, and directional cell growth.
