EPSPS — Brassica oleracea var. botrytis

Summary

BoEPSPS (EPSPS) on cauliflower chromosome 3 encodes a 3-phosphoshikimate 1-carboxyvinyltransferase, the enzyme that catalyses a key step in the shikimate pathway and is the target of the herbicide glyphosate. The protein localises to the chloroplast stroma and is associated with aromatic amino acid biosynthesis, response to herbicide, green leaf volatile biosynthesis, and circadian rhythm. The gene is linked to indole-3-acetic acid (IAA) content. 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 traits such as stem size, leaf temperature, chlorophyll content, photochemical quenching, and root morphology.
