Fig. 5. Endocytic pathway of the Arabidopsis cell visualized with FM4-64. FM4-64 was internalized from the plasma membrane (A and B), via motile dotted organelles (C) and ring-like organelles (C, arrowheads), to the vacuole (D). Bar, 10 µm. (E) Time course of the internalization of FM4-64. Percentages of cells with stained plasma membrane invaginations (i), dotty endosomes (d), ring-like structures (r) and vacuole (v) are plotted.
