Key Research Interests

My research interests include both pathogenic and mutualistic plant-virus interactions. The systems include Cucumber mosaic virus satellite RNA-induced tomato lethal disease and Nicotiana edwardsonii carrying endogenous virus, tobacco vein clearing virus.

Much of my research has been focused on programmed cell death involved in a non-coding RNA virus-induced crop disease. I employed cell biological, molecular, biochemical, genomic, functional genomic and genetic approaches to study the underlying regulatory mechanisms and explore alternative approaches for improving plant tolerance to virus infection. With the advances in next generation sequencing and RNA biology, my research interests have been extended to small RNA and viral RNA in vivo structure, and their roles in viral disease development and plant defense.

In the meantime, I discovered the conditional mutualistic relationship between pathogenic viruses and plant hosts which has since been confirmed by other agriculture research. I am interested in the impact of virus infection on host plant evolution. Thus, I choose Nicotiana edwardsonii containing endogenous virus in its genome as the research system. The virus can be activated under abiotic stress conditions. The activation mechanisms and its effect on host fitness are being investigated.
