Research

Our research aims to examine infection of S. sarrachoides by different strains of PVY and to study the symptoms and strain reactions in S. sarrachoides upon virus inoculation. We hypothesized that PVY infection will produce visible symptoms on S. sarrachoides plants and that symptom expression will vary depending on the PVY strain. We also compared the percentage of infection in S. sarrachoides vs. potato plants and assessed the virus titer upon aphid inoculation in these two closely related plants.
