Summary: The rice cytochrome P450 gene, specifically CYP90D5, has been found to play a crucial role in the degradation of isoproturon and acetochlor in rice plants. Its overexpression leads to increased resistance to these herbicides and improved plant growth. Additionally, CYP90D5 reduces the accumulation of isoproturon and acetochlor in rice while the CRISPR-Cas9 lines show the opposite effects, confirming its function in pesticide detoxification and degradation.

Summary: Rice is a staple crop for over half of the global population, but blast disease caused by Magnaporthe orzae can lead to significant yield losses. This study identifies a protein, OsUBC45, that enhances disease resistance and yield in rice. Overexpression of OsUBC45 increases resistance to both blast disease and bacterial leaf blight, while also increasing grain yield by over 10%.

Summary: Earthworms accelerated the degradation of the highly toxic acetochlor S-enantiomer in soil by synergistically promoting the degradation of both enantiomers with soil microorganisms. The presence of earthworms stimulated potential indigenous degraders and enabled the preferential degradation of the S-enantiomer in the soil-earthworm system, ultimately improving soil microbial activity and metabolic pathways.

Summary: Herbicides in wastewater pose a serious threat to environmental pollution. Impregnated metal zinc oxide catalysts (Cu/ZnO and Ni/ZnO) were prepared and characterized for the degradation of herbicides Isoproturon and triasulfuron. The combined effect of photocatalysis and sonication was utilized to investigate the degradation of selected herbicides. Optimization of parameters such as pH, irradiation time, photocatalyst dose, oxidants, ion effect, herbicide concentration, and catalyst reusability was conducted. The Cu/ZnO and Ni/ZnO photocatalysts achieved removal rates of 99% and 98% for isoproturon at pH 7 and 98% for triasulfuron at pH 6, and 99% for triasulfuron at pH 7, respectively.

Summary: In this study, four bacterial strains capable of degrading Isoproturon were isolated from agricultural soil. The mixed culture of these isolates exhibited complete degradation of the herbicide within 10 days. The inoculation of the mixed culture into soil increased the degradation rate of Isoproturon, and also caused short-term variations in bacterial structure. These findings are important for understanding the mechanisms of pesticide breakdown and bioremediation.

Summary: This study developed a genetically improved rice genotype by overexpressing a novel glycosyl-transferase gene named OsGT1 to accelerate the removal of butachlor residues in rice crop and its growth environment. The overexpression of OsGT1 significantly improved the growth of rice and attenuated the cellular damage caused by butachlor. The concentrations of butachlor in different parts of the rice plant were reduced, and the OsOE lines accumulated more degradative products than the wild-type, suggesting that more butachlor molecules were catabolized.

Summary: Developing sensitive practical sensors for monitoring pesticide residues in edible foods and environmental samples is of vital importance for food safety and environmental protection. In this study, a target triggered porphyrin metal-organic framework (MOF)-based nanosystem was designed with the dual functionality of sensitive detection and controllable degradation of the triazophos pesticide.

Summary: Agrochemicals such as pesticide residues pose ecotoxic risks to plant, animal, and human health. This study investigated the toxicology and degradation mechanisms of the widely used pesticide ametryn (AME) in rice crops. AME was found to be absorbed by rice roots, causing repression of plant elongation and reduction in dry weight and chlorophyll concentration. Transcriptome and metabolome analysis revealed AME-responsive genes and step-wise catabolism of AME in rice. The study also identified AME metabolites and conjugates that are closely related to differentially expressed genes, differentially accumulated metabolites, and activities of antioxidative enzymes. These findings contribute to the development of genetically engineered rice for bioremediation of AME-contaminated soils and reduction of AME accumulation in rice crops.

Summary: The constant use of oxyfluorfen (OFF) pesticide in farmland contaminates the soil and poses risks to crop growth and human health. To prevent food crops from being contaminated with OFF, understanding its absorption and degradation mechanisms is crucial. In this study, we characterized a new gene, OsACE2, which encodes a protein that can facilitate OFF degradation in rice. By overexpressing OsACE2, the growth of rice plants in a hydroponic medium was improved, with reduced oxidative stress caused by OFF. Additionally, we identified several metabolites of OFF and their pathways of degradation in rice.

Summary: This study investigated the toxicity, metabolic mechanism, and resultant pathways of bentazone (BNTZ) in rice. It was found that the growth of rice was compromised when treated with BNTZ at 0.2-0.8 mg/L (529.95-1060.05 g a.i./ha), and the activities of certain enzymes were elevated under BNTZ stress. Genome-wide RNA-sequencing analysis revealed that the degradative pathways of BNTZ in rice involve glycosylation, hydrolysis, acetylation, and conjugation processes catalyzed by enzymes. These findings provide valuable insights into the metabolic and detoxic mechanisms of BNTZ.
