Effect of glyphosate on symbiotic N2 fixation and nickel concentration in glyphosate-resistant soybeans
Decreased biological nitrogen fixation in glyphosate-resistant (GR) soybeans has been attributed directly to toxicity of glyphosate or its metabolites, to N2-fixing microorganisms. As a strong metal chelator, glyphosate could influence symbiotic N2 fixation by lowering the concentration of nickel (Ni) that is essential for the symbiotic microorganisms. Evaluation of different cultivars grown on...
متن کاملCompositional analysis of glyphosate-tolerant soybeans treated with glyphosate.
The compositional analyses and safety assessment of glyphosate-tolerant soybeans (GTS) were previously described. These analyses were extensive and included addressing the potential effects on seed composition from the genetic modification. Detailed compositional analyses established that GTS, which had not been treated with glyphosate, were comparable to the parental soybean line and to other ...
متن کاملNitrogenase activity, nitrogen content, and yield responses to glyphosate in glyphosate-resistant soybean
Transgenic glyphosate-resistant (GR) soybean [Glycine max (L.) Merr.] expressing a glyphosate-insensitive 5-enolpyruvylshikimate-3phosphate synthase (EPSPS) enzyme has provided new opportunities for weed control in soybean production. However, glyphosate is toxic to the soybean nitrogen-fixing symbiont, Bradyrhizobium japonicum, as its EPSPS enzyme is sensitive to glyphosate. The effects of gly...
متن کاملGlyphosate inhibits rust diseases in glyphosate-resistant wheat and soybean.
Glyphosate is a broad-spectrum herbicide used for the control of weeds in glyphosate-resistant crops. Glyphosate inhibits 5-enolpyruvyl shikimate 3-phosphate synthase, a key enzyme in the synthesis of aromatic amino acids in plants, fungi, and bacteria. Studies with glyphosate-resistant wheat have shown that glyphosate provided both preventive and curative activities against Puccinia striiformi...
متن کاملIsoflavone, glyphosate, and aminomethylphosphonic acid levels in seeds of glyphosate-treated, glyphosate-resistant soybean.
The estrogenic isoflavones of soybeans and their glycosides are products of the shikimate pathway, the target pathway of glyphosate. This study tested the hypothesis that nonphytotoxic levels of glyphosate and other herbicides known to affect phenolic compound biosynthesis might influence levels of these nutraceutical compounds in glyphosate-resistant soybeans. The effects of glyphosate and oth...
