BIP — Nicotiana attenuata

Summary

A4A49_18499 (BIP/ARF19) in coyote tobacco (Nicotiana attenuata) encodes a protein with DNA binding transcription factor activity, protein kinase activity, and identical protein binding, and contains ARF, AUX/IAA, B3, and PB1-like domains. It is associated with positive regulation of auxin mediated signaling pathway, response to cyclopentenone, inflorescence phyllotactic patterning, meristem development, root hair cell differentiation, and downregulation of lateral root development. The gene is linked to numerous traits including adventitious root number, lateral root number, phototropism response trait, plant male sterility, leaf vein morphology trait, gibberellin biosynthesis trait, and osmotic response sensitivity. It localizes to the nucleus, cytoplasm, plasmalemma, cell cortex, and vesicle. Studies of related genes in other species link the family to lateral root organogenesis, apical-basal patterning, and vascular tissue development.
