Current Research

My current research focuses on understanding the transcriptional regulatory programs controlling plant vascular tissue formation using the Arabidopsis root as a model system. Since vascular cells originate from meristematic cells of the procambium/cambium, the comprehensive gene expression profiling of this tissue will provide new insight into how gene regulation drives the biological function of these stem cells. To accomplish this, I am generating stage-specific GFP marker lines expressed exclusively in the procambium/cambium. These marker lines will be used for the transcriptome analysis of procambium/cambium cells through fluorescence-activated cell sorting. Based on those genome-wide expression data, the role of selected transcriptional regulators in determining vascular development will be further analyzed.
