Description

Multicellular organisms on earth start their life as a single cell, a zygote. The zygote undergoes tremendous times of cell division. Cells created from cell division generate different parts of the body. Although all the cells of multicellular organisms have the same set of genome, they differentiate to have different morphology and function, having different fates. It’s because the gene expression from their genome is differentially regulated from cells to cells. What genes are involved in creating different fates of each cell? How are the expression and function of those genes regulated differentially? These are my questions. To answer these questions, I study the cell fate determination mechanisms in Arabidopsis root cells. As a postdoctoral researcher, at the University of Michigan in Ann Arbor, I studied the molecular mechanism of epidermal cell fate determination in Arabidopsis roots. And I am continuing the research on the fate determination of different types of cells such as epidermal cells and root cap cells.
