PaWOX2 is important for correct differentiation of the protoderm. Images of LE1s in the control and line 35S:WOX2i.4 were acquired by laser scanning confocal microscopy. Cells are visible due to their intrinsic autofluorescence, when excited with strong intensity argon laser line at 488 nm. Images are pseudocolored green. Upper tier, maximum projection of a Z-stack (30 sequential stack images, 2 μm each optical section); Bottom tier, single optical layer images of the embryos shown in the upper tier. Bar, 50 μm
