BIP — Capsicum annuum

Summary

CaBIP (T459_19638) on pepper chromosome 7 encodes a protein with 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. The gene is associated with auxin signalling, ARF inactivation by AUX/IAA, and regulation of seed size, seed development and reproductive structure development. It is associated with positive regulation of auxin-mediated signalling, response to cyclopentenone and herbicide, meristem development, root hair cell differentiation, inflorescence phyllotactic patterning, and longitudinal axis specification. Associations with traits include adventitious root number, lateral root number, shoot system elongation rate, phototropism response, plant male sterility, leaf vein morphology, petiole length, gibberellin biosynthesis, and chlorophyll a content. The protein localises to the nucleus, cytoplasm, plasmalemma, vesicle and cell cortex.
