LDL3 is expressed in the plant meristems and callus tissue. The expression pattern of the LDL3 translational reporter (green) in untreated roots. Meristem, a root apical meristem; Elongation, an elongation region; LRP-1, an early lateral root primordium; LRP-2, a late lateral primordium. (a), in SAM with expression of the SAM markers pCLV3::dsRed and pWUS::mTq2 (magenta) (b), and in root explants undergoing regeneration processes (c). All panels in (a), lower panels in (b), and the panels of C0–7 and the inset of C14 in (c) are single optical sections; all other panels are projections from confocal Z-stacks. The panels of C14—C14S7 in (c) are combined images of two sequential projections. Cellular outlines were visualized with PI staining (magenta) (a and c). Scale bars: 100 µm (a and c) and 20 µm (b).
