EPSPS — Daucus carota subsp. sativus

Summary

DCAR_008553 (EPSPS) on carrot chromosome 2 encodes a 3-phosphoshikimate 1-carboxyvinyltransferase (EC 2.5.1.19), the EPSP synthase enzyme of the shikimate pathway. This gene is associated with aromatic amino acid biosynthesis, the shikimate pathway, and response to herbicide, including the annotated process of Roundup metabolism. It is linked to glyphosate sensitivity, IAA content, and photosynthetic rate. The encoded protein localises to the chloroplast stroma. Studies of related genes in other species link the EPSPS family to glyphosate tolerance and resistance, auxin content, and aromatic metabolism, while sequence similarity connections in other species associate the family with root morphology traits, chlorophyll content, and parasitic weed interactions.
