BIP — Asparagus officinalis

Summary

A4U43_C06F3760 (AoBIP) on asparagus chromosome 6 encodes an auxin-responsive protein with DNA-binding transcription factor activity, protein serine/threonine kinase activity, and domains including ARF, AUX/IAA, and PB1-like. It is associated with auxin signalling, ARF inactivation by AUX/IAA, and regulation of seed size and development. The gene is linked to numerous traits including adventitious root number, lateral root number, phototropism response, phyllotaxy, plant male sterility, shoot meristem development, vegetative to reproductive phase transition, and gibberellin biosynthesis. It localises to the nucleus, cytoplasm, plasmalemma, vesicle, and cell cortex. Related genes in other species are linked to lateral root formation, nuclear positioning, and auxin-responsive cell growth.
