Virus-induced gene silencing, geminivirus resistance

Research Interests

My lab is interested in virus-induced gene silencing and geminivirus-host interactions. Long-term goals are to understand how geminiviruses, which are DNA viruses that transcribe their genes in plant nuclei, interact with plant gene silencing pathways. We are currently mapping an Arabidopsis locus that confers resistance to two different genera of the Geminiviridae, begomoviruses and curtoviruses.
