OBE3 and WUS Interaction in Shoot Meristem Stem Cell Regulation
The stem cells in the shoot apical meristem (SAM) are the origin of all above ground tissues in plants. In Arabidopsis thaliana, shoot meristem stem cells are maintained by the homeobox transcription factor gene WUS (WUSCHEL) that is expressed in cells of the organizing center underneath the stem cells. In order to identify factors that operate together with WUS in stem cell maintenance, we per...
متن کاملStem cell regulation in the shoot meristem.
A small group of pluripotent stem cells in the shoot meristem is the ultimate source for all aerial parts in higher plants: the shoot axis, side branches, leaves and flowers. The stem cells are maintained in an undifferentiated state by signals from an underlying cell group, the organizing center. Genetic and molecular analyses have shown that a feedback signaling loop between stem cells and th...
متن کاملStem cell regulation in the Arabidopsis shoot apical meristem.
The aerial structure of higher plants is generated dynamically throughout the life cycle through the activity of stem cells that are located at the growing shoot tip, the apical meristem. The stem cells continuously divide to renew themselves and provide cells for leaf, stem and flower formation. Stem cell maintenance is governed by intercellular communication between the apical stem cells and ...
متن کاملRegulation of WUSCHEL Transcription in the Stem Cell Niche of the Arabidopsis Shoot Meristem W
Pluripotent stem cells are localized in specialized microenvironments, called stem cell niches, where signals from surrounding cells maintain their undifferentiated status. In the Arabidopsis thaliana shoot meristem, the homeobox gene WUSCHEL (WUS) is expressed in the organizing center underneath the stem cells and integrates regulatory information from several pathways to define the boundaries...
