EPSPS — Oryza sativa Indica Group

Summary

BGIOSGA022246 (EPSPS) on chromosome 6 of Indica rice encodes a 3-phosphoshikimate 1-carboxyvinyltransferase (EC 2.5.1.19), the EPSP synthase enzyme. The protein localises to the chloroplast stroma. This gene is associated with Roundup metabolism, response to herbicide, and glyphosate resistance, as well as green leaf volatile biosynthesis, circadian rhythm, and IAA content. It is linked to the chorismate biosynthesis pathway and general amino acid metabolism. Studies of related genes in other species connect the EPSPS family to glyphosate tolerance, aromatic metabolism, and fecundity, while sequence similarity in cereals links the family to grain yield, grain weight, plant height, seedling vigor, root morphology, and auxin content.
