HD1 — Oryza sativa Japonica

Summary

OS06G0583400 (HD1, also known as HDAC1) encodes a histone deacetylase (EC 3.5.1.98) with NAD-independent activity, and is annotated with histone deacetylase binding, histone binding, transcription corepressor activity, and structural constituent of chromatin functions. In rice, HD1 is associated with growth, root and lateral root development, and breeding traits. It is linked to flower formation, negative regulation of seed maturation, fruit abscission, and responses to drought, salinity, and ABA. The gene is also associated with grain plumpness, culm length, branch angle, leaf elongation rate, and metabolite content. HD1 localizes to the HDAC complex, PRC2 complex, condensed chromosome, nucleolus, and chloroplast envelope. Studies of related genes in other species link the family to flowering transition, flower development, systemic acquired resistance, seed viability, and responses to nutrient deficiencies.
