Ongoing ecological and evolutionary consequences by the presence of transgenes in a wild cotton population

Abstract After 25 years of genetically modified cotton cultivation in Mexico, gene flow between transgenic individuals and their wild relatives represents an opportunity for analysing the impacts of the presence of novel genes in ecological and evolutionary processes in natural conditions. We show c...
