BIP — Phaseolus vulgaris

Summary

PHAVU_009G224800, designated PvBIP, encodes a protein containing ARF, AUX/IAA, B3 DNA-binding and PB1-like domains, and exhibits DNA-binding transcription factor activity, protein serine/threonine kinase activity, and identical protein binding. In French bean, PvBIP is associated with positive regulation of auxin-mediated signaling, response to cyclopentenone, root hair cell differentiation, pigmentation, inflorescence meristem growth, and embryonic pattern specification. The gene is linked to numerous traits including seed coat color and pattern, phototropism response, adventitious and lateral root number, leaf vein morphology, phyllotaxy, plant male sterility, and gibberellic acid sensitivity. Studies of related genes in other species connect the family to lateral root development, vascular tissue identity specification, apical-basal patterning, flowering time, and stress response.
