Plant diseases caused by viruses constitute a major constraint to crop production worldwide. More than a thousand viruses are known to infect plants and account for about 50% of all newly emerging plant viruses. Mitigating yield losses caused by plant viruses is therefore crucial to ensure the world meets the demand of a growing population.
My research is focused on engineering attenuated plant viruses (Plant virus "vaccines") for use in "vaccinating" plants against the wild type viruses, using Pepino Mosaic Virus, an emerging pathogen of tomato, as a model.
