EPSPS — Brassica juncea

Summary

BjEPSPS (BJUA04G29070S) on Indian mustard chromosome A04 encodes a 3-phosphoshikimate 1-carboxyvinyltransferase, the EPSP synthase enzyme. The gene is associated with aromatic amino acid family anabolism, amino acid anabolism, shikimate pathway, chorismate biosynthesis, amino acid biosynthesis, and amino acid metabolism. It is linked to Roundup metabolism, response to herbicide, green leaf volatile biosynthetic process, and circadian rhythm. The product localises to the chloroplast stroma. Associations with stem size, IAA content, and chlorophyll content have been noted. Studies of related genes in other species connect the EPSPS family to glyphosate tolerance and resistance, auxin content, fecundity, and aromatic metabolism, as well as to traits such as leaf temperature, photochemical quenching, and root morphology.
