BP — Oryza sativa Indica Group

Summary

BGIOSGA009880 (BP, also known as OiBP, OSH15, OSH1, STM) on chromosome 3 of Indica rice encodes a homeodomain-containing transcription factor with KNOX2 and TALE homeobox domains, annotated with DNA-binding transcription factor activity, RNA polymerase II-specific, and additional molecular functions including ATP-dependent chromatin remodeler activity, miRNA binding, and protein folding chaperone activity. The gene is associated with shoot organ boundary specification, formation of plant organ boundaries, regulation of gibberellin biosynthetic process, negative regulation of auxin-mediated signaling, and somatic stem cell population maintenance. It is linked to brassinosteroid and gibberellin pathways, and to phenotypes including dwarfism, altered architecture, and growth. Associations extend to traits such as seed yield, grain shattering, inflorescence development, leaf morphology, root development, heterosis, and responses to light intensity and boron sensitivity. The protein localizes to the nucleus, cytoplasm, plastid, plasmodesma, and microtubule cytoskeleton.
