BIP — Oryza sativa Japonica

Summary

OS06G0196700, also known as BIP, ARF11, ARF16, OsIAA25, OsARF7, ARF19, OsIAA21, IAA23, OsIAA22, IAA22, OsIAA23, NPH4, and OsBIP on rice chromosome 6, encodes a protein with DNA-binding transcription factor activity, including promoter-specific chromatin binding and cis-regulatory region sequence-specific DNA binding, and also possesses protein serine/threonine kinase activity. The protein localizes to the nucleus, cytoplasm, plasmalemma, cell cortex, and vesicles. In rice, this gene is associated with flag leaf angle, iron and phosphate signaling, auxin and cytokinin responses, root and shoot architecture, lateral root development, and biomass. It has been linked to grain thickness, tiller angle, amylose content, leaf width, adventitious root number, phototropism, plant male sterility, and cellulose content. Studies of related genes in other species associate the family with lateral root development, vascular tissue specification, shoot regeneration, flowering time, and stress responses.
