HD3A — Oryza sativa Indica Group

Summary

BGIOSGA022349 (HD3A/RFT1) on chromosome 6 of Indica rice encodes a phosphatidylethanolamine-binding protein (PEBP family) and is associated with phosphatidylethanolamine binding. The gene is associated with the regulation of flowering time, heading date, and the transition from vegetative to reproductive phases, as well as photoperiodism, vernalization response, and inflorescence development. It has been linked to floral and shoot apical meristem activity, grain traits, strigolactone signaling, amino acid content, leaf and shoot development, growth, and domestication. Associations also include grain yield, grain weight, grain number, grain color, grain filling period, plant height, maturity time, cold tolerance, chlorophyll content, protein content, heterosis, and anthesis time. The protein localizes to the cytoplasm, nucleus, and endoplasmic reticulum and participates in pathways for florigen expression, drought escape, and the formation of the RFT1:14-3-3:FD1 complex.
