BP — Oryza sativa Indica Group
Summary
BGIOSGA013637 (OiBP, also known as OSH15, OSH1, BP1, and STM) encodes a homeodomain-containing transcription factor with KNOX1, KNOX2, and ELK domains, and is annotated with DNA-binding transcription factor activity, ATP-dependent chromatin remodeler activity, and miRNA binding. In indica rice, the gene is associated with brassinosteroid and gibberellin pathways, shoot and inflorescence meristem identity, organ boundary specification, and plant architecture, with observed phenotypes including dwarfism and altered growth. It is linked to traits such as seed yield, leaf morphology, root development, heterosis, and responses to boron and light intensity. The gene product localizes to the nucleus, cytoplasm, plasmodesma, and microtubule cytoskeleton. Studies of related genes in other species connect the family to shoot apical meristem maintenance, compound leaf development, and stress responses.
