The Site of the Inhibition of the Shikimate Pathway by Glyphosate: II. INTERFERENCE OF GLYPHOSATE WITH CHORISMATE FORMATION IN VIVO AND IN VITRO
Open accessAbstract
In the presence of the nonselective herbicide glyphosate (N-[phosphonomethyl]glycine), buckwheat (Fagopyrum esculentum Moench) hypocotyls and cultured cells of Galium mollugo L. accumulate an organic acid, which was identified as shikimate by mass-spectroscopy of its methyl ester. After growth in 0.5 millimolar glyphosate for 10 days, G. mollugo cells contained shikimate in amounts of up to 10% of their dry weight. Synthesis of chorismate-derived anthraquinones in G. mollugo was blocked by glyphosate. Chorismate and o-succinylbenzoate (an anthraquinone precursor) alleviated the inhibition. The conclusion drawn from these experiments, that glyphosate inhibits a step in the biosynthetic sequence from shikimate to chorismate, was substantiated by the finding that glyphosate is a powerful inhibitor of the conversion of shikimate to chorismate in cell-free extracts from Aerobacter aerogenes 62-1.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
