Effects of Glyphosate on Shikimic Acid Accumulation in Tobacco Cell Cultures with Low and High Yields of Cinnamoyl Putrescines
To study the flow of carbon through the shikimate pathway in tobacco cell cultures with low and high yields of cinnamoyl putrescines, the cell cultures were treated with glyphosate. In the presence of glyphosate the levels of free shikimic acid were increased more than 300-fold by both cell lines. Despite of a normally 10-fold higher level of cinnamoyl putrescines, the high yielding cell line a...
متن کاملEvaluation of spectrophotometric and HPLC methods for shikimic acid determination in plants: models in glyphosate-resistant and -susceptible crops.
Endogenous shikimic acid determinations are routinely used to assess the efficacy of glyphosate in plants. Numerous analytical methods exist in the public domain for the detection of shikimic acid, yet the most commonly cited comprise spectrophotometric and high-pressure liquid chromatography (HPLC) methods. This paper compares an HPLC and two spectrophotometric methods (Spec 1 and Spec 2) and ...
متن کاملTris[(6S)-6-hydroxy-4-epi-shikimic acid] monohydrate: an enantiomerically pure hydroxylated shikimic acid derived from methyl shikimate
The title compound, 3C(7)H(10)O(6)·H(2)O, is the enanti-omerically pure product of a multi-step synthesis from the enanti-omerically pure natural shikimic acid. The asymmetric unit contains three mol-ecules of the acid and one mol-ecule of water. The cyclo-hexene rings of the acids have half-chair conformations. The carboxyl-ate, the four hydroxide groups and the additional water mol-ecule form...
متن کاملOn the mode of incorporation of shikimic acid into 2-hydroxy-1,4-naphthoquinone (lawsone).
incorporation of this acid in vitamin K 2 23 and vitamin K t 4 in bacteria and higher plants. Degradation of labeled vitamin K 2 after feeding shikimic acid (-U-1 4C) has shown that the intact ring of this acid is incorporated into the benzenoid moiety of this naphthoquinone 2 ' 3 . fn contrast, the degradation studies on lawsone 1 indicated that the ring atoms of shikimic acid (-U-1 4C) are tr...
متن کاملAminomethylphosphonic acid, a metabolite of glyphosate, causes injury in glyphosate-treated, glyphosate-resistant soybean.
Glyphosate-resistant (GR) soybean [Glycine max (L.) Merr.] was developed by stable integration of a foreign gene that codes insensitive enzyme 5-enolpyruvylshikimate-3-phosphate synthase, an enzyme in the shikimate pathway, the target pathway of glyphosate. Application of glyphosate to GR soybean results in injury under certain conditions. It was hypothesized that if GR soybean is completely re...
