BP — Oryza sativa Japonica

Summary

OSH1 (BP, OsSTM) on rice chromosome 3 encodes a homeodomain-containing KNOX transcription factor with DNA-binding transcription factor activity, RNA polymerase II-specific, and is also annotated with ATP-dependent chromatin remodeler activity, miRNA binding, protein folding chaperone, translation initiation factor activity, and microtubule binding. The gene is associated with shoot organ boundary specification, periclinal cell division, somatic stem cell population maintenance, regulation of gibberellin biosynthetic process, and negative regulation of auxin-mediated signaling. It has been linked to brassinosteroid phytohormone pathways, growth, architecture, and dwarf phenotypes. Associations include grain shattering, seed weight, panicle number, culm number, inflorescence branching, submergence tolerance, boron sensitivity, plastochron, and vegetative to reproductive phase transition. Localization evidence connects the product to the nucleus, cytoplasm, plasmodesma, plastid, endosome, and microtubule cytoskeleton.
