Sublethal application of various sulfonylurea and imidazolinone herbicides favors outcrossing and hybrid seed production in oilseed rape [PDF]

BMC Plant Biology, 2020
Background Acetolactate synthase (ALS)-inhibiting herbicides from the chemical families of sulfonylureas and imidazolinones are used worldwide. However, drift or sprayer contamination from some sulfonylurea herbicides causes a high level of male ...

Effect of deashing on physico-chemical properties of wheat and rice straw biochars and potential sorption of pyrazosulfuron-ethyl

Arabian Journal of Chemistry, 2020
Abstract Wheat (WBC) and rice straw biochars (RBC) prepared at 400 and 600 °C and their deashed counterparts were characterized for their physico-chemical properties using CHN analysis, Brunauer–Emmett–Teller (BET), X-ray fluorescence (XRF), scanning electron microscopy (SEM), 13 C-nuclear magnetic resonance (NMR), X-ray diffraction (XRD) and ...

Stacked mutations in multi-copy AHAS genes enhance sulfonylurea herbicide resistance in soybean. [PDF]

Plant J
SUMMARY Weeds are a major factor that negatively impact crop yields. Developing herbicide‐resistant germlines is crucial for efficient weed control. Sulfonylurea‐ and pyrimidinyl benzoate‐based herbicides inhibit the function of acetohydroxyacid synthase (AHAS), a key enzyme in the biosynthesis of branched‐chain amino acids in plants. To create soybean

Degradation of Pyrazosulfuron Ethyl in Rice Ecosystem by Aspergillus terreus

Current Journal of Applied Science and Technology, 2021
Investigation on the degradation of pyrazosulfuron ethyl by Aspergillus terreus in the rice ecosystem was conducted at the Department of Biochemistry, UBKV, Pundibari Coochbehar, West Bengal, India. The soil was collected from the paddy field to isolate fungal inoculums.

Heterologous expression of CYP81A6 from rice (Oryza sativa) in Escherichia coli and structural analyses of bensulfuron‐methyl metabolites

Weed Biology and Management, Volume 21, Issue 3, Page 164-171, September 2021., 2021
Abstract Herbicides are often selective and kill only weeds without affecting crops. In rice, CYP81A6 is responsible for tolerance toward acetolactate synthase herbicides such as bensulfuron‐methyl (BSM). CYP81A6 is thought to metabolize BSM into a nontoxic metabolite, that is, O‐demethylated BSM.

Agrochemical leaching reduction in biochar‐amended tropical soils of Belize

European Journal of Soil Science, Volume 72, Issue 3, Page 1243-1255, May 2021., 2021
Abstract The aim of this study was to determine the effects of biochar addition on agrochemical leaching in tropical soils of Belize. Biochars were produced from mixed softwood, rice husk and miscanthus straw, each pyrolysed at 700°C. Loam, sandy silt loam and clay loam tropical soils were amended with 0, 1, 2.5 and 5% (w/w) biochar to determine ...

Unraveling the Role of P450 Reductase in Herbicide Metabolic Resistance Mechanism. [PDF]

Plant Direct
ABSTRACT Plants require cytochrome P450 reductase (CPR) to supply two electrons for cytochrome P450 monooxygenase enzymes (P450) to react with an organic substrate. The transfer of electrons to the P450 active site in the P450 catalytic site relies on a robust and intricate CPR:P450 complex in the endoplasmic reticulum membrane.

Cyanobacteria-Pesticide Interactions and Their Implications for Sustainable Rice Agroecosystems. [PDF]

Int J Microbiol
Modern agricultural practices rely heavily on fertilizers and pesticides to boost crop yields, essential for feeding the growing global population. However, their extensive use poses significant environmental risks. Chemical‐based fertilizers and pesticides persist in ecosystems, potentially harming ecological stability.
