Effects of Prior Host Infection Status on New Infections
Grapevine leafroll disease (GLD) has spread to all grape-growing regions and is one of the most important viral diseases affecting grapevines worldwide. GLD has adverse effects on fruit quality and plant health, leading to significant economic losses. Grapevine leafroll associated virus 3 (GLRaV-3) is the primary causative virus involved in GLD. Given the economic importance of grapes and the consequences of GLD, it is crucial to develop efficient ways of managing this disease.
Recent studies have demonstrated that abiotic conditions such as plant nutrient status, accumulation of inorganic metals, temperature, and plant water status can alter viral dynamics, increase resistance to pathogens, and confer benefit to plant hosts under stress. The goal of my research is to test the effects of nutrient availability on plant susceptibility to GLRaV-3 infections and symptom severity. My research will provide insight for novel management approaches for plant viral diseases.
