Herbicide resistance could confer an advantage on plants in the wild. 
Overexpression of epsps transgene in weedy rice: insufficient evidence to support speculations about biosafety.
There is a lack of evidence in the paper that the EPSPS transgene confers glyphosate resistance, or that the transgenic weedy rice is more competitively fit than its wild type in the absence of glyphosate treatment, and the findings are not as novel as the authors imply.
Howwas the glyphosate-resistant transgenic line that overexpressed epsps developed ?
Gressel et al. (2014; in this issue of New Phytologist, pp. 360–362) disapprove of media coverage of our recent peer-reviewed paper (Wang et al., 2014; this issue ofNewPhytologist, pp. 679–683), and
Overexpressing Exogenous 5-Enolpyruvylshikimate-3-Phosphate Synthase (EPSPS) Genes Increases Fecundity and Auxin Content of Transgenic Arabidopsis Plants
The results from Arabidopsis with nine transgenic events provide a strong support to the hypothesis that transgenic plants overproducing EPSPS can benefit from a fecundity advantage in glyphosate-free environments.
The Relationship Between Agricultural Law and Environmental Law in the United States of America
Agricultural law and environmental law in the United States are individually vast areas of legislation, regulation, and jurisprudence involving a wide array of objects, actors, rights, and duties.


A novel 5-enolpyruvoylshikimate-3-phosphate (EPSP) synthase transgene for glyphosate resistance stimulates growth and fecundity in weedy rice (Oryza sativa) without herbicide
It is hypothesized that over-expressed epsps may be useful to breeders and, if deployed, could result in fitness benefits in weedy relatives following transgene introgression.
