...The majority of this increase is the result of glyphosate use on soybean, cotton, canola, and corn crops that have been genetically modified to tolerate this glyphosate (e.g., Roundup Ready crops) (Cerdeira and Duke, 2006; Young, 2006)....

...However, since this publication, several weed species have evolved resistance to glyphosate (Heap et al., 2005; Nandula et al., 2005) (Table 5), apparently through several different mechanisms....

...Although there are hundreds of cases of evolved resistance of weeds in fields of non-transgenic crops (Heap et al., 2005), there are no proven cases of introgression of herbicide resistance gene(s) from a naturally-resistant crop to an associated weed....
