Resistance to the widely used herbicide, glyphosate, has evolved through target-site CNV in many weedy plant species, including the economically important grass, Eleusine indica (goosegrass); however, the origin and mechanism of these CNVs remain elusive in many weed species due to limited genetic and genomic resources.
Experiments were conducted to evaluate the single effect of soybean competition and its combined effect with a glyphosate field dose (1,080 g a.e. ha-1) on the growth and fitness of plants carrying glyphosate resistance endowing target site mutations.
