Atrazine-induced oxidative stress on soybeans could be mitigated by atrazine degrading bacterium, whether the mitigation enhanced supplementary regulating plant nutrient utilization is unclear. In this study, soybean was sown into 20 mg kg -1 of contaminated soil which supplemented with atrazine-degrading bacterium Arthrobacter sp. DNS10 and/or inorganic phosphorus-solubilizing Enterobacter P1, removal, phosphorus and were investigate d. Compared to strain or P1 inoculation treatment, co-inoculation treatment improved degradation in decreased accumulation leaves, consequently seedling growth. The also atrazine-induced antioxidant enzymes activities malonaldehyde contents, as well increased chlorophyll total concentration leaves. Transcriptome analysis highlighted that co-inoculated strains up-regulated expression genes related photosynthetic-antenna proteins, carbohydrate metabolism fatty acid All results suggest mitigate induced accelerating removal from enhancing transcriptome. These findings deepen understanding molecular mechanism alleviation conducted pollutant regulation.
