Impact of a new pesticide on rhizosphere microbes and plant health:case study of Y17991 against sharp eyespot in wheat

Sharp eyespot(rhizoctonia cerealis) is a widespread soil-borne fungal disease that poses a severe threat to wheat health, and it is one of the main obstacles to achieving stable and high-quality wheat yields in china. Our collaborative team has developed a novel, efficient, and low-toxicity fungicide named Y17991(n-(2-(2,4-bis-(trifluoromethyl)phenoxy)phenyl)-3-(difluoromethyl)-1-methyl-1h-pyrazole-4-carboxamide). Preliminary laboratory tests confirmed the significant inhibitory effect of this agent on r. cerealis. Large-area field trials also demonstrated its efficacy, with a disease prevention index of 83.52%, which is 1.97% greater than that of the widely used thifluzamide, and it significantly increased the wheat yield. Moreover, this study explored the impacts of Y17991 on the structure and function of the microbial community in wheat rhizosphere soil. bacterial communities were more strongly affected than fungal communities. Y17991 significantly modulated key amino acid metabolic pathways and certain biosynthetic processes in diseased wheat rhizospheres, and it also enhanced certain biosynthetic pathways and metabolic activities in healthy wheat rhizospheres. Additionally, the application of Y17991 regulated rhizosphere metabolites, thus exerting significant control over the microbial community. We identified 15 microbial strains potentially involved in the prevention and treatment of r. cerealis, and Y17991 treatment promoted the growth of Pedobacter and bacillus strains. These strains not only aid in plant growth but they also have the potential for disease prevention. In summary, Y17991 application at a reasonable dose does not cause significant disruption to nontarget rhizosphere microbial communities. In future studies, we will continue to investigate the impacts of Y17991 on nonmicrobial components in soil ecosystems, such as protozoa and nematodes. Our research provides a theoretical basis for the scientific application and promotion of new fungicides a

Ischemic stroke(IS) is a prevalent neurological disorder often resulting in significant disability or mortality. resveratrol, extracted from Polygonum cuspidatum Sieb. et Zucc.(commonly known as Japanese knotweed), has been recognized for its potent neuroprotective ***, the neuroprotective efficacy of its derivative,(E)-4-(3,5-dimethoxystyryl) quinoline(rV02), against ischemic stroke remains inadequately explored. This study aimed to evaluate the protective effects of rV02 on neuronal ischemia-reperfusion injury both in vitro and in vivo. The research utilized an animal model of middle cerebral artery occlusion/reperfusion and Sh-SY5Y cells subjected to oxygen-glucose deprivation and reperfusion to simulate ischemic conditions. The findings demonstrate that rV02 attenuates neuronal mitochondrial damage and scavenges reactive oxygen species(rOS) through mitophagy activation. Furthermore, Parkin knockdown was found to abolish rV02's ability to activate mitophagy and neuroprotection in vitro. These results suggest that rV02 shows promise as a neuroprotective agent, with the activation of Parkin-mediated mitophagy potentially serving as the primary mechanism underlying its neuroprotective effects.

Mesoporous titanium dioxide spheres were synthesized by a convenient solvothermal method at room temperature with tetraethyl titanate as a precursor. Investigation by means of X-ray diffraction（XrD）, transmission electron microscopy（TEM）, scanning electron microscopy（SEM）, and n2 adsorption-desorption isotherms confirms that the sample has a mesostructure with a higher specific surface area and shows that the mesoporous TiO2 spheres have a diameter of 2 μm, the average pore size is about 5.9 nm, and the bET surface area and specific pore volume are about 236 m2/g and 2.116 cm3/g, respectively. The anatase and rutile mesoporous TiO2 spheres calcined at 700 °c show much better photocatalytic activity than the samples calcined at other temperatures and is comparable to an uncalcined sample in the photodegradation of Methyl blue（Mb） under the UV irradiation.
