Identification and Characterization of Downy Mildew-Responsive microRNAs in Indian by High-Throughput Sequencing.

Downy mildew (DM) is one of the most devastating diseases disturbing viticulture, mainly during temperate and humid climates. The DM pathogen can attack grapevine leaves and berries differentially, and the disease is managed with recurring applications of fungicides that direct pathogen pressure, develop of resistant strains, and lead to residual soil toxicity and increased pollution effects. Plant microRNAs (miRNAs) are important candidates in physiological regulatory roles in response to biotic stress in plants.

Gamma-irradiated fenugreek extracts mediates resistance to rice blast disease through modulating histochemical and biochemical changes.

The impact of gamma radiation on the activation of rice innate immunity to blast disease caused by Magnaporthe oryzae is described. In the present study, fenugreek seed extracts radiated with different doses of gamma rays viz. 5Gy, 10Gy, 15Gy, 20Gy and 25Gy were examined for their presence of biocompounds as well as for its ability to induce plant growth promotion and resistance against rice blast disease.

Influence of triazole pesticides on tillage soil microbial populations and metabolic changes.

Pesticides are generally applied to agricultural soil to control crop diseases, with the critical goal of preventing yield loss and optimizing economic returns. However, the excessive utilization of pesticides in agriculture is a severe environmental and human health problem. In the present study, effect of triazole based fungicide, propiconazole on soil physicochemical properties, stimulatory impact of propiconazole residue on soil microbial communities and soil enzyme activities (phosphatise and urease) in contaminated red sandy loam and deep black soils of paddy (Oryza sativa L.
