Research Visits

Prof. Dr. Lawrence Bogorad, Department of Cellular and Molecular Biology, Harvard University, 24 August 1992 - 21 August 1994, USA. Mechanisms for regulating the cell specificity of rbcS-m3 gene in maize are elucidated. Protein binding sequences which are required for rbcS-m3 gene regulation are identified. Gene cloning, polymerase chain reaction, sequencing, gene transfer, and gel retardation approaches are used to unravel the complexity of rbcS-m3 gene regulation

Prof. Dr. Charles Arntzen, Boyce Thompson Institute for Plant Research, Cornell University, 25 August - 10 September 1999, USA. Plant transformation mediated by Agrobacterium tumefaciens has become the most used method for the introduction of foreign genes into plant cells and the subsequent regeneration of transgenic plants. Genetic transformation mediated by Agrobacterium involves the transfer of a DNA molecule (T-DNA) from the bacterium to the eukaryotic host cell, and its integration into the host genome. Agrobacterium-mediated transformation parameters were optimized for potato shoot explants using β-glucuronidase (GUS) as a reporter gene

Prof. Dr. Richard Meagher Department of Genetics, University of Georgia, 2 September 2000 - 1 September 2002, USA. The cytoskeleton is important for controlling cell shape and cell motility and for organizing signaling complexes. Additionally, connections are being found between cytoskeletal proteins and the regulation of gene expression in the nucleus. Gene silencing is an effective experimental tool to study gene functions in plants. In recent years, sequence-specific gene silencing has become more popular because of its powerful effect to inhibit the expression of a homologous endogenous gene. RNA interference (RNAi) is one of these means to induce a gene-specific block to translation. The basic mechanism of RNAi is that the presence of dsRNA can target specific mRNAs for degradation, resulting in silencing their expression in a homology-dependent way. Two important events happened in the RNA interference pathway: (1) the formation of small interfering RNAs (siRNAs) and microRNAs (miRNAs) cut by the RNase III enzyme Dicer and (2) the cleavage and destruction of homologous mRNA by an RNA-induced silencing complex directed by siRNAs, or the block of its translation. Analysis of RNAi knockdown is typically performed by Western blot. Downregulation of cytoskeleton genes by RNA interference (RNAi) in Arabidopsis plants revealed its role in plant development

Research Interests

My main research interest focuses on functional genomics. Differential expression of potato WRKY1 gene was analyzed upon Erwinia carotovora infection. An exhaustive search was performed in GenBank for WRKY genes and predicted a WRKY-like gene in tomato using bioinformatics tools. A major challenge in the post-genome era of plant biology is to determine the functions of all the genes in the plant genome. A straightforward approach to this problem is to reduce or knock out expression of a gene with the hope of seeing a phenotype that is suggestive of its function. Insertional mutagenesis is commonly used in large-scale plant functional genomics, as mobile DNA tags of known sequence can be utilized to retrieve flanking gene sequences. RNA interference (RNAi) is a useful tool for this type of study, using constructs encoding self-complementary ‘hairpin’ RNA. These applications have been used very effectively to high-throughput Arabidopsis thaliana functional genomics. Arabidopsis profilin gene (PRF1) was analyzed by RNAi and phylogenetic approaches. Abiotic stresses such as drought dramatically influence the yield of many important crop plants. To overcome the yield losses due to abiotic stresses, plants need to possess mechanisms of avoidance and tolerance to stress. For sustainable agriculture development, future crops should have abiotic stress resistant traits and the mechanism for stress tolerance. Genetic enhancement of crop tolerance to abiotic stress can be improved by employing plant molecular biology and genomics tools. A T-DNA insertion mutant for NaCl-hypersensitivity was characterized in Arabidopsis thaliana. Apolipoprotein E (APOE) has been studied for its potential role in osteoporosis risk in human. Genetic variation at APOE locus modulates bone mineral density. The association of the APOE gene polymorphisms with bone-related phenotypes is determined
