Cell-type specific expression of mTRQ2-MerC-SYP121 in the root tip (a) and the elongation zone (b) of roots of Col-0 (wild-type) and the pEpi plants (lines 8 and 20). FM4-64 was applied for 3–5 min before laser scanning microscopic analyses. Scale bars = 50 µm. The areas indicated with white dashed lines in the merge images (b) are shown with higher magnifications in Fig. 4 for subcellular localization analysis.
