Low PI4P and PI(4,5)P2 levels correlate with stem cell maintenance. Signal intensity profile across the diameter of shoot meristems expressing (a, b) pPDF1::mCitrine-PHPLC (n = 18) and (c, d) pPDF1::mCitrine-P4MSidM (n = 18). (a, c absolute value and b, d relative values after normalization by the meristem diameter). The diameter of the pPDF1::mCitrine-PHPLC-depleted domain was equal to 20% of that of the whole meristem with a standard deviation of 0.05; the diameter of the pPDF1::mCitrine-P4MSidM-depleted domain was equal to 57% of that of the whole meristem, with a standard deviation of 0.144. Shoot meristems expressing (e) pPDF1::mCitrine-PHPLC and (f) pPDF1::mCitrine-P4MSiDM in Col-0 (left panel) or clv3-17 (right panel). Note the presence of a few dead cells in the central zone of the meristem at the bottom right panel. Scale bar, 20 μm
