EPSPS — Brassica juncea

Summary

BJUB01G49170S (BjEPSPS) on Indian mustard chromosome B01 encodes a 3-phosphoshikimate 1-carboxyvinyltransferase, the EPSP synthase enzyme of the shikimate pathway. The gene is associated with aromatic amino acid family anabolism, the shikimate pathway, and response to herbicide, and has been specifically annotated to Roundup metabolism. It is linked to green leaf volatile biosynthetic process and circadian rhythm, and the product localises to the chloroplast stroma. Associations with stem size, chlorophyll content and IAA content have been recorded. Studies of related genes in other species link the EPSPS family to glyphosate tolerance, glyphosate resistance, auxin content and fecundity, and transferred evidence connects the family to glyphosate sensitivity, leaf temperature, photochemical quenching and root morphology traits.
