RESEARCH INTERESTS:

The long-term goal of my research is to elucidate the functions and biochemical mechanisms of RNA silencing in plants. RNA silencing has emerged as a key regulatory process that controls various aspects of biology in eukaryotes including growth and development and antiviral defense. The common themes of RNA silencing include the biogenesis of small RNAs by DICERs, and the incorporation of small RNAs into Argonaute (AGO)-centered RNA-induced silencing complexes (RISCs). The RISCs execute the repressive or regulatory functions on target genes at the transcriptional or post-transcriptional levels. Our research has four major aspects: 1) Arabidopsis AGO10 and stem cell development; 2) Novel biochemical mechanisms of microRNA biogenesis in plants; 3) Interplay between RNA processing and transcriptional gene silencing; and 4) Epigenetic silencing and viral suppressors. We address these fundamental issues using integrated molecular, biochemical, genetic, genomic and high-throughput and other the state-of-the-art approaches.
