DEP1 — Oryza sativa Indica Group

Summary

BGIOSGA030843 (DEP1, OiDEP1) on chromosome 9 of Indica rice encodes a GG3-like domain-containing protein. This gene is associated with grain yield, seed size, panicle architecture, effective panicle number, plant architecture, and development. It has been linked to cadmium response, cell death, and breeding traits. The encoded protein localises to the plasmalemma and nucleus and is associated with floral organ structural organisation, regulation of seed development, GPCR signalling, ABA signalling, and detoxification. Associations also include rachis length, panicle number and length, spikelet number, grain length and size, plant height, leaf length and shape, heterosis, nitrogen response, abscisic acid response, phytohormone and gibberellin pathways, root and shoot traits, tillering, amylopectin chain-length distribution, and grain quality. Studies of related genes in other species link the family to grain yield, grain shape, amylose content, salinity tolerance, and cytoplasmic male sterility.
