No fitness cost of glyphosate resistance endowed by massive EPSPS gene amplification in Amaranthus palmeri

Amplification of the EPSPS gene has been previously identified as the glyphosate resistance mechanism in many populations of Amaranthus palmeri, a major weed pest in US agriculture. Here, we evaluate the effects of EPSPS gene amplification on both the level of glyphosate resistance and fitness cost...
