研究领域
Viruses are simple but fascinating microbes. Because of the lack of cellular structures, viruses depend entirely on cellular organisms for their perpetuation. Viruses are important in a number of ways. First, they are major pathogens of humans, animals, and plants. Second, reliance of viruses on cellular structures and functions has made viruses ideal tools to study and advance several biological disciplines such as molecular biology, cell biology and immunology.
Research in my laboratory encompasses both basic and applied aspects, with the ultimate goal of understanding viruses and viral diseases for the betterment of agriculture. This goal is being achieved through investigations using multi-disciplinary approaches including those used in virology, molecular biology, cell biology and biochemistry and through national and international collaborations. Our research involves a number of important viruses that infect plants, which include Grapevine rupestris stem pitting-associated virus (GRSPaV), a ubiquitous and important pathogen of grapes worldwide.
We were the first to unravel the genome sequence and structure of GRSPaV. We have discovered that GRSPaV is composed of a wide range of sequence variants. We have demonstrated that most commercial grape varieties are infected with multiple sequence variants and proposed that the existence of multiple viral variants in a single grapevine likely resulted from grafting between scions and rootstocks. Furthermore, we have developed serological and nucleic acid-based methods for the rapid detection of GRSPaV. Recently, we have developed infectious cDNA clones for GRSPaV. We are exploring the possibility of developing GRSPaV into a virus-induced gene silencing vector for the elucidation of grapevine genes and genetic sequences.
Current research directions:
Processing and subcellular localization of the replicase polyprotein of GRSPaV.
Elucidation of function of the novel Alkylation B (AlkB) domain in the replicase polyprotein of GRSPaV and closteroviruses.
Structure and cellular localization of viral replication complexes.
Evolution biology and bio-informatics of major grapevine viruses
Development of virus-induced gene-silencing vectors for beneficial applications. Development and application of highly efficient and economical technologies for the diagnosis of major grapevine viruses.
