BP — Oryza sativa Indica Group

Summary

BGIOSGA009879 (OiBP, also known as OSH15, OSH1, STM, and BP1) on chromosome 3 of Indica rice encodes a KNOX1 domain-containing protein with DNA-binding transcription factor activity, RNA polymerase II-specific, and ATP-dependent chromatin remodeler activity. It is associated with shoot organ boundary specification, regulation of gibberellin biosynthesis, miRNA processing, somatic stem cell population maintenance, and negative regulation of auxin-mediated signaling. The gene is linked to plant architecture, growth, dwarfism, brassinosteroid pathways, and numerous traits including seed yield, inflorescence and leaf morphology, grain shattering, panicle development, flowering time, and biotic stress response. Localization evidence places the product in the nucleus, cytoplasm, plasmodesma, plastid, and microtubule cytoskeleton. Studies of related genes in other species connect the family to shoot meristem function, organ separation, and responses to drought and salt stress.
