Molecular Identification And Characterization Of Viral Pathogens Infecting Sweet Cherry, Aaron J. Simkovich
Molecular Identification And Characterization Of Viral Pathogens Infecting Sweet Cherry, Aaron J. Simkovich
Electronic Thesis and Dissertation Repository
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 …

Community Engaged Learning Final Projects
LIFE*SPIN is a local organization in London, Ontario that provides resources to individuals and families dependent on low income to ultimately break the poverty cycle by encouraging sustainable living and self-sufficiency. For this Seminar in Biology course, Maria Bata and I partnered with LIFE*SPIN to plan and execute a "Seeding Planting Party" to teach children about basic botany, nutrition, and leadership. The following final paper for this seminar discusses the project deliverables and efforts, biological research concerning companion planting, and personal reflection on this experience.

Part of the resistance mechanism of soybean (Glycine max [L.] Merr.) to Phytopthora sojae Kauf. & Gerd. involves pre-formed root suberin. In order to investigate the role of suberin in this host-pathogen interaction, I characterized hairy roots, formed as a result of Agrobacterium rhizogenes (Riker et al.) Conn infection, as a model to be used as a reliable soybean transformation system. I established hairy root cultures and demonstrated that they were a result of A. rhizogenes infection. The anatomy and suberin deposition in soybean hairy roots was examined, and found to be very similar to that of wild-type roots. …
