A mechanistic framework for noncell autonomous stem cell induction in Arabidopsis
Open accessAbstract
Significance: Cell–cell communication is a prerequisite of multicellular development and noncell autonomous stem cell induction has been conserved during evolution. Cytoplasmic bridges, called plasmodesmata, which facilitate the exchange of molecules between neighboring cells, are a striking innovation for cell–cell signaling in plants. Here, we show that plasmodesmata function is required for the activity of shoot apical stem cells in Arabidopsis and provide evidence that the stem cell inducing transcription factor WUSCHEL moves from the niche into the stem cells via this route. WUSCHEL movement is functionally relevant and mediated by multiple protein domains. Because parts of the protein that restrict movement are required for homodimerization, the formation of WUSCHEL dimers might contribute to the regulation of stem cell activity in Arabidopsis .

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
