Glyphosate resistance of C3and C4weeds under rising atmospheric CO2

Abstract

The present paper reviews current knowledge on how changes of plant metabolism under elevated CO2concentrations (e[CO2]) can affect the development of the glyphosate resistance of C3and C4weeds. Among the chemical herbicides, glyphosate, which is a non-selective and post-emergence herbicide, is currently the most widely used herbicide in global agriculture. As a consequence, glyphosate resistant weeds, particularly in major field crops, are a widespread problem and are becoming a significant challenge to future global food production. Of particular interest here it is known that the biochemical processes involved in photosynthetic pathways of C3and C4plants are different, which may have rele..
