DEP — Oryza sativa Indica Group

Summary

BGIOSGA002579 (DEP, also known as OiDEP or DEP1) on chromosome 1 of Indica rice encodes an uncharacterized protein with methylthioribulose 1-phosphate dehydratase and acireductone synthase activities. The protein contains HAD-like and enolase-ppase_E1 domains and localises to chloroplast stroma, plastids, mitochondria and cytosol. DEP is associated with abscisic acid signalling, detoxification, and the biological processes GO:0019509 and GO:0009856. The gene is linked to grain yield, grain weight, grain length and size, panicle number and length, spikelet number, plant height, rachis length, leaf length and shape, heterosis, and seed and flower development. Studies of related genes in other species link the family further to grain appearance, tiller number, harvest index, and tolerance to salinity and cold.
