Molecular Mechanisms of Viral Resistance and Susceptibility in Ostreococcus tauri

Although marine viruses control blooms and shape the evolution of biodiversity in phytoplankton, little is known about the factors governing resistance and susceptibility of their hosts. Combining genomics with expression data and flow cytometry is a novel approach to study host-virus interactions in marine protists. Genetic transformation will be used to increase or decrease the expression of genes potentially involved in virus resistance/susceptibility. The resulting resistant or susceptible phenotypes will be studied using microbiology and molecular biology techniques, and flow cytometry. Gene expression, latent period, burst size and host specificities will be assessed. Determining the genes involved in viral resistance and susceptibility of the green alga O. tauri will help to understand basic viral resistance in phytoplankton.
