EPSPS — Brassica napus

Summary

BnEPSPS (DARMORV10_A04P33720.1) on chromosome A04 of oilseed rape encodes a 3-phosphoshikimate 1-carboxyvinyltransferase, the EPSP synthase enzyme of the shikimate pathway. This gene is associated with aromatic amino acid family anabolism, secondary metabolism, and response to herbicide, including Roundup metabolism. It has been linked to chlorophyll fluorescence, green leaf volatile biosynthetic process, immune response, circadian rhythm, cell wall modification, ribosome biogenesis, RNA processing, mitosis, and syngamy. The encoded protein localises to the chloroplast stroma. Associations with leaf temperature and IAA content have also been recorded. Studies of related genes in other species link the EPSPS family to glyphosate tolerance and resistance, auxin content, fecundity, and aromatic metabolism, as well as to traits such as stem size, chlorophyll content, photochemical quenching, and root morphology.
