HD1 — Oryza sativa Indica Group

Summary

BGIOSGA006874 (HD1) on chromosome 2 of Indica rice encodes a histone deacetylase (EC 3.5.1.98) with NAD-independent activity, and also carries domains associated with protein kinase activity and chromatin binding. The gene product is linked to histone deacetylase binding, histone demethylase activity, transcription corepressor activity, and structural chromatin roles. It is associated with stress responses including salt and osmotic stress resistance, as well as growth, root development, and seed maturation. The gene has been connected to traits such as panicle number, spikelet fertility, fruit quality, and plant size, and to processes including fruit abscission, floral organ development, and regulation of flowering time. It localizes to HDAC and PRC2 complexes, the chloroplast envelope, and the perinuclear ER membrane. Studies of related genes in other species link the family to abiotic stress tolerance, flowering transition, and reproductive development.
