BIP — Solanum tuberosum

Summary

PGSC0003DMG400002392, also known as BIP or ARF16, encodes an auxin response factor on potato chromosome 7. The protein contains B3 DNA-binding, AUX/IAA and PB1-like domains and is associated with sequence-specific DNA-binding transcription factor activity and protein serine/threonine kinase activity. It localises to the nucleus, cytoplasm, plasma membrane and vesicles. ARF16 is associated with defence response, leaf curvature, positive regulation of auxin-mediated signalling, inflorescence meristem growth, secondary growth, root hair cell differentiation, and downregulation of lateral root development. The gene is linked to numerous traits including root weight, leaf margin morphology, adventitious root number, phototropism, phyllotaxy, plant male sterility, gibberellin biosynthesis, and cytokinin sensitivity. Studies of related genes in other species connect the family to lateral root organogenesis, vascular tissue development, fruit set, parthenocarpy, and stress response.
