Isoflavone, Glyphosate, and Aminomethylphosphonic Acid Levels in Seeds of Glyphosate-Treated, Glyphosate-Resistant Soybean

Journal of Agricultural and Food Chemistry, 2002
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 ...

The control of Asian rust by glyphosate in glyphosate‐resistant soybeans

Pest Management Science, 2007
AbstractBACKGROUND: Glyphosate is a widely used broad‐spectrum herbicide. Recent studies in glyphosate‐resistant (GR) crops have shown that, in addition to its herbicidal activity, glyphosate exhibits activity against fungi, thereby providing disease control benefits.

Glyphosate Affects Seed Composition in Glyphosate-Resistant Soybean

Journal of Agricultural and Food Chemistry, 2010
The cultivation of glyphosate-resistant (GR) soybeans has continuously increased worldwide in recent years mainly due to the importance of glyphosate in current weed management systems. However, not much has been done to understand eventual effects of glyphosate application on GR soybean physiology, especially those related to seed composition with ...

Compositional Analysis of Glyphosate-Tolerant Soybeans Treated with Glyphosate

Journal of Agricultural and Food Chemistry, 1999
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

Glyphosate Can Decrease Germination of Glyphosate-Resistant Soybeans

Journal of Agricultural and Food Chemistry, 2017
We investigated the effects of different concentrations of glyphosate acid and one of its formulations (Roundup) on seed germination of two glyphosate-resistant (GR) and one non-GR variety of soybean. As expected, the herbicide affected the shikimate pathway in non-GR seeds but not in GR seeds.

Monitoring glyphosate residues in transgenic glyphosate‐resistant soybean

Pest Management Science, 2003
Abstract The availability of Roundup Ready (RR) varieties of soybean has increased the use of glyphosate for weed control in Argentina. Glyphosate [( N ‐phosphonomethyl)glycine] is employed for the eradication of previous crop vegetation and for weed control during the ...

Glyphosate in northern ecosystems

Trends in Plant Science, 2012
Glyphosate is the main nonselective, systemic herbicide used against a wide range of weeds. Its worldwide use has expanded because of extensive use of certain agricultural practices such as no-till cropping, and widespread application of glyphosate-resistant genetically modified crops.

Glyphosate bioavailability in soil

Biodegradation, 2009
Biodegradation of glyphosate in sod-podzol soil by both the indigenous micro flora and the introduced strain Ochrobactrum anthropi GPK 3 was studied with respect to its sorption and mobility. The experiments were carried out in columns simulating the vertical soil profile.

Glyphosate Degradation in Glyphosate-Resistant and -Susceptible Crops and Weeds

Journal of Agricultural and Food Chemistry, 2010
High levels of aminomethylphosphonic acid (AMPA), the main glyphosate metabolite, have been found in glyphosate-treated, glyphosate-resistant (GR) soybean, apparently due to plant glyphosate oxidoreductase (GOX)-like activity. AMPA is mildly phytotoxic, and under some conditions the AMPA accumulating in GR soybean correlates with glyphosate-caused ...

Sustainability and Stewardship of Glyphosate and Glyphosate-resistant Crops

Weed Technology, 2007
The significance of glyphosate and the appearance of glyphosate-resistant weeds have raised concerns about glyphosate sustainability. Resistance-prevention strategies, however, should first consider the mechanisms for resistance. For example, target-site resistance can provide virtual immunity, ensuring that every herbicide application successfully ...
