EPSPS — Brassica oleracea var. botrytis

Summary

BoEPSPS, encoded by the cauliflower gene BOLND125_C04P077540.1 on chromosome 4, is a 3-phosphoshikimate 1-carboxyvinyltransferase enzyme of the EPSP synthase family, localised to the chloroplast stroma. It is associated with the shikimate pathway, aromatic amino acid biosynthesis, and the metabolism of the herbicide Roundup, as well as with response to herbicide, green leaf volatile biosynthesis, and circadian rhythm. The gene is also linked to indole-3-acetic acid (IAA) content. Studies of related genes in other species connect the EPSPS family to glyphosate tolerance and resistance, herbicide sensitivity, auxin content, fecundity, and traits including stem size, leaf temperature, chlorophyll content, photochemical quenching, and root morphology.
