BRD1 — Oryza sativa Indica Group

Summary

BGIOSGA011773 (BRD1, OiBRD1) on chromosome 3 of Indica rice encodes a bromodomain-containing protein with histone acetylase activity toward H3 and H4, mRNA and DNA binding, and is a component of the SWI-SNF and histone acetylase complexes localised to the nucleus and plasmodesmata. The gene is associated with regulation of photoperiodic flowering, vegetative growth, root morphogenesis, chlorophyll anabolism, and co-transcriptional chromatin reassembly. It has been linked to grain shape, grain size, grain yield, plant height, and chlorophyll content. Related genes in other species connect the family to leaf thickness, leaf angle, brassinosteroid content, grain number, flowering time, root length, and drought tolerance.
