Impact of glyphosate on the Bradyrhizobium japonicum symbiosis with glyphosate-resistant transgenic soybean: a minireview.

Lack of glyphosate resistance gene transfer from Roundup Ready soybean to Bradyrhizobium japonicum under field and laboratory conditions.

A field study was conducted at the Russell E. Larson Agricultural Research Center to determine the effect of transgenic glyphosate-resistant soybean in combination with herbicide (Roundup) application on its endosymbiont Bradyrhizobium japonicum. DNA of bacteroids from isolated nodules was analysed for the presence of the transgenic 5-enolpyruvylshikimate-3-phosphate synthase (CP4-EPSPS) DNA se...

Impact of glyphosate application to transgenic Roundup Ready soybean on horizontal gene transfer of the EPSPS gene to Bradyrhizobium japonicum and on the root-associated bacterial community

Nitrogenase 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...

The Probability of a Horizontal Gene Transfer from Roundup Ready® Soybean to Root Symbiotic Bacteria: A Risk Assessment Study on the GSF Lysimeter Station

The gene transfer from glyphosate tolerant soybean to Bradyrhizobium japonicum was evaluated in a free-air lysimeter experiment under natural conditions and increasing selection pressure, to monitor for the probability of horizontal gene transfer (HGT). A large volume lysimeter study that offers conditions comparable to normal farming was conducted in 2004 and 2005 with Roundup Ready® (RR) soyb...

A Review on Production of Glyphosate-Resistant Plants with Emphasis on Molecular Methods

Herbicide-resistant plants are one of the most common plants that comprise the majority of the total population of transgenic plants. Glyphosate is an herbicide that controls a wide range of plant species. Position of these herbicides reaction is 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) that only exists in plants and some bacteria. This herbicide was known to be suitable and safe for...
