What are the genetic and molecular basis of herbicide resistance in bacteria?
5 answers
The genetic and molecular basis of herbicide resistance in bacteria involves various mechanisms. Bacteria can evolve resistance to herbicides like glyphosate by reducing sensitivity or increasing production of the target enzyme, EPSP synthase. Additionally, mutations in key residues of the target enzyme, acetohydroxyacid synthase (AHAS), can reduce herbicide binding affinity and abolish time-dependent accumulative inhibition, leading to resistance. Herbicides have been found to promote horizontal gene transfer (HGT) of antibiotic resistance genes (ARGs) in soil bacteria by inducing changes in cell-to-cell contact, membrane permeability, and proton motive force, facilitating DNA uptake and spread of resistance genes. Understanding these mechanisms is crucial for developing strategies to mitigate the spread of herbicide resistance in bacterial populations.
