EPSPS — Nicotiana attenuata

Summary

A4A49_05371 (EPSPS-1) in Nicotiana attenuata on chromosome 1 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 family anabolism, the shikimate pathway, and chloroplast stroma localization. It has been linked to Roundup metabolism, response to herbicide, detoxification, regeneration, green leaf volatile biosynthesis, circadian rhythm, protein splicing, and homologous recombination. Associations with IAA content and photosynthetic rate have also been noted. Related genes in other species link the EPSPS family to glyphosate tolerance and resistance, auxin content, fecundity, and aromatic metabolism, as well as traits including root morphology, chlorophyll content, and parasitic weed interactions.
