Stone fruits are a valuable crop grown worldwide, however pathogens such as viruses threaten fruit production by reducing tree health and fruit yield. In an orchard within the Niagara region of Ontario, symptoms typical of viral infection such as chlorosis and leaf deformation were seen on sweet cherry (Prunus avium L.) trees. Next generation sequencing was performed on symptomatic and asymptomatic leaves and four viruses were identified. On the tree displaying the most severe symptoms, Prune dwarf virus (PDV), was the only virus detected. A survey conducted during this work showed 42% of cherry trees on a single …

Currently no vaccine has been developed that can prevent the spread of HIV-1. During sexual transmission, a single viral variant called the Transmitted/Founder (T/F) purportedly with unique physical properties, establishes infection in 70-80% of individuals. Unlike previous studies that have tried to identify T/F viruses based on their structure glycan composition and amino acid sequence, we have analyzed the RNA sequences of HIV-1 to help identify T/F variants. Using a combination of both in silico data analysis and in vitro assays, we have identified that T/F viruses have higher numbers of immunostimulatory motifs than HIV virions that fail to infect. …
