Abstract
Bentazone (BNTZ) is a selective and efficient herbicide used in crop production worldwide. However, the persistence of BNTZ residues in the environment has led to their increasing accumulation in farmland and crops, posing a high risk to human health. To evaluate its impact on crop growth and environmental safety, a comprehensive study was conducted on BNTZ toxicity, metabolic mechanism, and resultant pathways in rice. The rice growth was compromised to the treatment with BNTZ at 0.2-0.8 mg/L (529.95-1060.05 g a.i./ha), while the activities of enzymes including SOD, POD, CAT, GST, GT, and CYP450 were elevated under BNTZ stress. A genome-wide RNA-sequencing (RNA-Seq) was performed to dissect the variation of transcriptomes and metabolic mechanisms in rice exposed to BNTZ. The degradative pathways of BNTZ in rice are involved in glycosylation, hydrolysis, acetylation, and conjugation processes catalyzed by the enzymes. Our data provided evidence that helps understand the BNTZ metabolic and detoxic mechanisms.
