Role of WUSCHEL in Regulating Stem Cell Fate in the Arabidopsis Shoot Meristem
The shoot meristem gives rise to the aerial parts of higher plants by continuously initiating new organs. The basis of this activity is its ability to maintain a pool of pluripotent stem cells, which are the ultimate source of all tissues of the shoot. In Arabidopsis plants mutant for the WUSCHEL (WUS) gene, the stem cells are misspecified and appear to undergo differentiation. Here, we show th...
متن کاملAPETALA2 Regulates the Stem Cell Niche in the Arabidopsis Shoot Meristem W
Postembryonic organ formation in higher plants relies on the activity of stem cell niches in shoot and root meristems where differentiation of the resident cells is repressed by signals from surrounding cells. We searched for mutations affecting stem cell maintenance and isolated the semidominant l28 mutant, which displays premature termination of the shoot meristem and differentiation of the s...

متن کاملThe Arabidopsis embryonic shoot fate map.
A fate map has been constructed for the shoot apical region of the embryo of the dicotyledonous plant Arabidopsis thaliana using spontaneously arising clonal albino sectors caused by the chloroplast mutator 1-2 mutation. Chimeric seedlings exhibiting albino sectors shared between the cotyledons and first true leaves revealed patterns of organ inclusion and exclusion. Frequencies of clone sharin...
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 ...
