    • Abstract:In multicellular organisms, development of cells and organs is controlled by gene expression at the specific cell or developmental stage. To know the function of genes in Arabidopsis root at the levels of the specific cell type and developmental stage, I did whole transcriptome analysis from all cell types and developmental stages in Arabidopsis root. I found that alternatively spliced isoforms were more differentially expressing between the developmental zones, however not so much changing between specific cell types. These data suggest that alternatively spliced isoforms control root meristem development rather than cell type specific development. I will present the data to show that alternatively splicing isoforms control root meristem development.
      Stem cell niche and root meristem size are maintained by intercellular interactions and signaling networks of a plant peptide hormone, Root Meristem Growth Factor 1 (RGF1). How RGF1 regulates root meristem development is an essential question to understand stem cell function. Although five receptors of RGF1 have recently been identified, the downstream signaling mechanism remains unknown. I will present a series of signaling events following RGF1 action and the data to show the function of a novel transcription factor, which plays a central role in mediating RGF1 signaling.
