HD1 — Oryza sativa Japonica

Summary

OsHD1 (OS08G0344100) encodes a histone deacetylase with NAD-independent activity, also annotated with histone demethylase, transcription regulator, and transcription corepressor activities, and is a component of HDAC and Sin3-type complexes. In rice, OsHD1 is associated with stress responses including salt and osmotic stress resistance, and with seedling and seed traits. The gene is linked to flower formation, negative regulation of seed maturation, fruit abscission, and regulation of multicellular organismal development. Associations also include grain plumpness, culm length, floral organ length, plant female sterility, and responses to rice thrips, radiation, and sulfur. Studies of related genes in other species link the family to female gametophyte development, post-germination growth, systemic acquired resistance, and abiotic stress tolerance.
