Fig. 5. Fluorescence confocal microscopy images of Arabidopsis thaliana after treatment with compound 4. Fluorescence images highlight the accumulation of compound 4 in the vasculature of new leaves upon cotyledon loading: (a) green fluorescence emission from compound 4, (b) red fluorescence emission from chlorophyll, (c) merged fluorescent images from (a) and (b) including an overlay brightfield image. Scale bar: 250 μm. (d) High-magnification dual-colour image highlighting the localisation of compound 4 in chlorophyll-rich cells in the vascular region. Scale bar: 25 μm.
