Dr. Tanveer Fatima Rizvi completed her Ph.D under the guidance of Prof. M. R. Khan in the Department of Plant Protection, Aligarh Muslim University. She has made major scientific contributions in environmental pollution, plant diseases and bio management, and effect of nanoparticles on plants and microbes.
Her research work based on effect of CO2 on the sensitivity of cucurbits to SO2 and their susceptibility to powdery mildew disease caused by S. fuliginea. In India, co-occurrence of CO2 or SO2 and fungal pathogens of plants exists in fields near coal powered industries and other CO2 or SO2 sources. Studies have shown both stimulatory and inhibitory effects of air pollutants on plant pathogens. In order to investigate this aspect, systematic studies were carried out by Dr. Fatima, under the Ph. D. program to ascertain and examine the effect of CO2 or SO2 on the powdery mildew of five commonly grown cucurbits caused by Sphaerotheca fuliginea under open top chambers.
In her study Dr. Fatima observed that SO2 exposures promoted the fungal pathogenesis, and, the disease became much severe causing greater yield decline to all five cucurbit species. As a result, the reduction in the growth of fungus inoculated plants was further increased at 50 and 75 ppb SO2 exposures. Whereas, with the CO2 exposures, the disease severity was greater, but cumulative suppressive effect was decreased. Overall, the plant growth was marginally greater than the control especially at 600 ppm CO2. The concomitant exposure with CO2 and SO2 also influenced the growth of fungus infected cucurbit plants. The CO2 exposures apparently countered the suppressive effect of SO2. Reductions in the plant growth, dry weight of shoot and root were non-significant in CO2+SO2 exposed and fungus infected plants in comparison to the control.
Her study has demonstrated that elevated levels of CO2 and SO2 can substantially influence the host-pathogen relationship as well as severity of plant diseases as observed for powdery mildew on five cucurbit species in the her study. However, the effects varied greatly with the two gases tested. This has revealed that both the gasses may promote the severity of plant diseases and the consequent impact on the plant growth depended on the synergy with the S. fuliginea, indicating that the two gases may play key role in the host-pathogen relationship.
