Transcriptional profiling of the Arabidopsis root quiescent center

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 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.

A Mobile miR160-Triggered Transcriptional Axis Controls Root Stem Cell Niche Maintenance and Regeneration in Arabidopsis

Project description:In multicellular organisms, communication between cells is vital for their fate determination. In plants, the quiescent center (QC) signals to adjacent stem cells to maintain them undifferentiated. However, how surrounding stem cells instruct the QC remains poorly understood. Here we show that in the Arabidopsis root, microRNA160 (miR160) moves from vascular stem cells to the QC, where it degrades the mRNAs of two auxin response factors, ARF10 and ARF17. This degradation relieves BRAVO from direct transcriptional repression, maintaining QC quiescence. We further identify that blocking miR160 movement due to DNA damage-induced vascular stem cell death and restricted symplastic transport reduces BRAVO and WOX5 expression, leading to QC division to replenish damaged stem cells during root regeneration. Together, our results demonstrate that a transcriptional axis initiated by mobile miR160 regulates the QC and stem cell behavior, advancing our understanding of the communication between stem cells and their surrounding cellular environment.

Vascular specific H3K27me3 and H3K4me3 profile in the Arabidopsis root

Project description:We isolated Vascular specific root protoplast using the pWOL:GFP marker line (Birnbaum et al., 2003) and Fluorescence Activated Cell Sorting (FACS). FACS-treated root protoplast from wild type plants (Col0) were used as control. The GFP positive protoplast from the pWOL:GFP line and WT protoplast were used for a ChIP-seq experiment using H3K27me3 and H3K4me3 antibodies.

Time course of the Arabidopsis root stem cells

Project description:The goal of this dataset was to transcriptionally profile the Arabidopsis root stem cells over developmental time. To accomplish this, we protoplasted roots expressing PET111:GFP every 8 hours from 4 days to 6 days old. We then collected GFP negative cells from the PET111:GFP line using cell sorting, as these cells represent the stem cell population. RNA was extracted from cells, libraries were prepared, and RNA-seq was performed. FPKM values were calulcated using Cufflinks.

APC/CCCS52A2 repressed phytosulfokine signaling restricts root QC cell proliferation through ERF115 degradation

Project description:The quiescent center (QC) plays an essential role during root development by creating a microenvironment that preserves the stem cell fate of its surrounding cells. Strikingly, in order to retain root structure, QC cells only occasionally self-renew, displaying a proliferation rate far below that of all other cells within the root meristem. Previously, the APC/CCCS52A2 ubiquitine ligase and brassinosteroid signaling pathways have been found to antagonistically control Arabidopsis thaliana QC cell proliferation. Here, we demonstrate that both pathways converge on the ERF115 transcription factor that acts as a rate-limiting factor of QC cell division through transcriptional control of the autocrine phytosulfokine PSK5 peptide hormone. ERF115 marks QC cell division but is restrained through proteolysis by the APC/CCCS52A2 ubiquitine ligase, whereas QC proliferation is driven by brassinosteroid-dependent ERF115 expression. Combined, these two antagonistic mechanisms delimit the ERF115-PSK5 activity and QC renewal. Our results reveal a unique cell cycle regulatory mechanism that accounts for the low proliferation rate of QC cells within a surrounding population of highly mitotic active cells.
