WebApr 15, 2024 · Glyphosate is the most common broad-spectrum herbicide. It targets the key enzyme of the shikimate pathway, 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), which synthesizes three essential aromatic amino acids (phenylalanine, tyrosine and tryptophan) in plants. Because the shikimate pathway is also found in many … WebSince the herbicide glyphosate (N-(phosphonomethyl)glycine) was commercialized in 1974, it has become the most widely used herbicide in the world, due largely to the wide scale adoption of transgenic, glyphosate-resistant (GR) crops after their introduction in 1996 ( ). In GR crops, this relatively high use rate herbicide (commonly 0.5 to 2.0 ...
