Simplified shikimate/chorismate biosynthesis pathway, and shikimate abundance in leafy spurge tissues after glyphosate-treatment. (a) The pathway links the metabolism of carbohydrates to the biosynthesis of the aromatic amino acids (phenylalanine, tyrosine and tryptophan). The pathway is specific to microorganisms and plants; in plants the pathway appears to occur in plastids. Glyphosate is known to inhibit 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) of the chorismate biosynthetic pathway. Red italic text indicates the genes involved in particular step/s of the pathway. (b) Shikimate abundance 7 days (d) post-treatment in aerial tissues which were directly exposed to glyphosate, in crown buds which were indirectly exposed to glyphosate 7 d post-treatment, and in aerial tissues derived from crown buds of foliar glyphosate-treated leafy spurge plants after decapitation (7 d post-treatment) and regrowth for six weeks. Shikimate abundance data represent the mean of four biological and two technical replicates obtained from fresh tissue (FW); vertical bars indicate ± SE of the mean
