Confocal Live Imaging of Shoot Apical Meristems from Different Plant Species

The shoot apical meristem (SAM) functions as a conserved stem cell reservoir and it generates almost all aboveground tissues during the postembryonic ...

The control of the location and activity of stem cells depends on spatial regulation of gene activities in the stem cell niche. Using computational and experimental approaches, we have tested and found support for a hypothesis for gene interactions that specify the  apical stem cell population. The hypothesis explains how the WUSCHEL gene product, synthesized basally in the meristem, induces -expressing stem cells in the meristem apex but, paradoxically, not in the basal domain where  itself is expressed. The answer involves the activity of the small family of  genes, which prevent the activation of  and which are expressed basally in the shoot meristem.
