BP — Oryza sativa Indica Group
Summary
BGIOSGA013638 (BP, also known as OSH15, OSH1, and STM) encodes a homeodomain-containing transcription factor belonging to the KNOX protein family, with DNA-binding transcription factor activity and RNA polymerase II-specific cis-regulatory region binding. In indica rice, this gene is associated with brassinosteroid and gibberellin biosynthesis pathways, shoot and inflorescence meristem identity, organ boundary specification, and floral whorl morphogenesis. It has been linked to plant architecture, growth, dwarfism, and developmental traits including leaf, root, flower, spikelet, grain, and seed characteristics. Associations also extend to auxin content, boron sensitivity, heterosis, stomatal patterning, and biotic stress responses. The protein localizes to the nucleus, cytoplasm, plasmodesma, plastid, and microtubule cytoskeleton. Studies of related genes in other species connect the family to shoot apical meristem maintenance, compound leaf morphology, and grain shattering.
