Plants form new organs from pluripotent stem cells throughout their lives and under changing environmental conditions. In the Arabidopsis root meristem, a pool of stem cells surrounding a stem cell organizer, named Quiescent Center (QC), gives rise to the specific root tissues. Among them, the ...
Throughout the lifespan of a plant, which in some cases can last more than one thousand years, the stem cell niches in the root and shoot apical meristems provide cells for the formation of complete root and shoot systems, respectively. Both niches are superficially different and it has rema...
root and shoot meristems use related factors for stem cell maintenance. In the root niche the quiescent centre cells, surrounded by the stem cells, express the homeobox geneWOX5(WUSCHEL-RELATED HOMEOBOX 5)1, a homologue of theWUSCHEL(WUS) gene that non-cell-autonomously maintains stem cells ...
A SCARECROW-RETINOBLASTOMA Protein Network Controls Protective Quiescence in the Arabidopsis Root Stem Cell Organizer Quiescent long-term somatic stem cells reside in plant and animal stem cell niches. Within the Arabidopsis root stem cell population, the Quiescent Centre ... A Cruz-Ramírez,S Díaz-...
The PLETHORA genes mediate patterning of the Arabidopsis root stem cell niche. A small organizing center, the quiescent center (QC), maintains stem cells in the Arabidopsis root and defines the stem cell niche. The phytohormone auxin ... M Aida,D Beis,R Heidstra,... - 《Cell》 被引量:...
On the contrary, the expressions of KNOLLE and CYCB1;1, two cell cycle markers, were both downregulated in phb3 (Figures S1B, S1C, S1E, and S1F). All these results indicate that PHB3 is required for maintaining the cell division activity of the root meristem. The observation that PHB3...
WT plant has been detected, one can hypothesize that a local deregulation of auxin homeostasis or distribution can maybe suppress local cell death, as it has been recently demonstrated that DNA damage-triggered cell death in root stem cell could be largely inhibited by low levels of auxin39...
Markers (M1 to M3) indicate 0, 1 and 2 endoreduplication events, respectively. (e) The proportion of cell ploidy levels (n¼3). M1, M2 and M3 represent 2C, 4C, 8C nuclei in a diploid, respectively, and 4C, 8C and 16C nuclei in a tetraploid, respectively. (f) The ...
