Cytokinin-deficiency enhanced tolerance to chloroacetanilide herbicide metolachlor
Original language description
Plant responses to synthetic organic compounds (xenobiotics) involve coordinated physiological, biochemical and signaling events. Cytokinin acts in the integration of growth control and stress response and recent works demonstrated various effects of cytokinin on glutathione content and glutathione-dependent detoxification of toxic metals/metalloids. However, the role of cytokinin in plant responses to organic xenobiotic which sequestration relies on glutathione conjugation remains to be elucidated. Here, for the first time, we probed the role of cytokinin in plant response to xenobiotics whose detoxification pathway involves formation of glutathione conjugates. We found that increased endogenous cytokinin content lowers plant resistance to triazine herbicide atrazine, chloroacetanilide herbicides, such as alachlor and metolachlor, and herbicide safeners benoxacor and fenclorim. The cytokinin-deficient plants even exhibited an enhanced tolerance to metolachlor. Altogether, we found that cytokinin modulates xenobiotic stress response, which might be of potential importance in herbicide selectivity or phytoremediation strategies.
