RAB — Phaseolus vulgaris

Summary

PHAVU_001G235000, designated PvRAB, encodes a C2H2-type zinc-finger transcription factor with a plant development regulator domain. Located in the nucleus, it is associated with DNA-binding transcription factor activity and regulation of DNA-templated transcription. Annotated biological processes include regulation of meristem organisation, nodulation, cell division, vesicle transport, and response to cold. Phenotypic associations link this gene to floral organogenesis, including reduced second-whorl organs, extra sepals with fusion, and altered petal development, as well as cytokinesis, cell geometry, hypocotyl growth, and cellulose biosynthesis. Studies of related genes in other species connect the family to petal size, petal morphology, floral organ development, organ identity, salt response, and directional cell growth.
