Project description:The establishement of the first plant tissues occurs during embryo development. Indeed, cell types that will form the Arabidopsis root stem cell niche are first specified during 16-cell (16C), early globular (EG) and late globular (LG) stage of embryonic development. While some regulatory factors are known, we do not yet understand the genetic networks underlying the specification of these cell types. One main reason for this is the difficulties in adapting genome-wide approaches to the cellular level. Here, we have adapted such an approach (INTACT) to generate microarray-based cell type-specific transcriptomic profiles at 16C to LG stage for use in determining the role of the transcriptome in cell specification and differentiation during root stem cell niche formation.

Project description:The RETINOBLASTOMA–RELATED (RBR) is a key regulator of cell proliferation and differentiation in plants, and plays an important role in maintenance of the stem cell niche in the root. We used microarray analysis to characterize the transcriptional response of Arabidopsis thaliana root tips from rRBr mutant (7 samples) against Col-0 wild type (6 samples) after 4, 6 and 10 das.

Project description:The Arabidopsis quiescent center (QC) is a small group of cells with low mitotic activity located at the center of the root stem cell niche. Its transcriptional profile was previously analyzed using two repeats of cells FACS isolated using the WOX5 marker. To get more power in analyzing QC transcriptional profile, we generated three additional samples of the QC, using the QC-specific marker WOX5.

Project description:A gene expression map of Arabidopsis thaliana shoot apical meristem stem cell niche was generated by isolating the specific cell type using the cell sorting methods. We used ap1-1;cal1-1 mutant background to enrich the sufficient number of cells for microarray analysis. Spatial and temporal regulation of gene expression is critical for stem-cell homeostasis. The shoot apical meristems of Arabidopsis thaliana harbor a small set of stem-cells which are surrounded by several million differentiating cells, imposing a severe limitation on the genomic analyses of stem-cell homeostasis. We have employed cell type-specific gene expression profiling that allowed us to generate a high-resolution gene expression map and it has revealed gene expression networks specific to the cell types of the stem-cell niche. We demonstrate that the expression map can be used to predict in vivo gene expression domains to identify novel gene expression patterns. Furthermore, it has revealed molecular pathways that are conserved among plant and animal stem-cell populations. The expression map should guide future reverse genetics experiments, high-resolution analyses of cell-cell communication networks and epigenetic modifications. Keywords: cell type comparison

Its transcriptional profile was previously analyzed using two repeats of cells FACS isolated using the AGL42 marker. To get more power in analyzing QC transcriptional profile, we generated three additional samples of the QC, using the QC-specific marker WOX5. Three replicates of FACS-sorted GFP-positive cells from WOX5:GFP roots.

Experiment Overall Design: Three replicates were used CLV3p, CLV3n and FILp, while for WUSp only two replicates were used. CLV3n cells lacks CLV3p cell type.
