Endocytosis in different regions of L. chinensis roots and intracellular stages of endocytosis. Plant materials were grown as in Fig. 1. The endomembrane system was monitored by incubating the roots with the fluorescent membrane probe FM4-64 for 30 min before imaging. Typical bright-field and confocal scanning laser microscopy images are shown. (A) Endocytosis in different regions of L. chinensis roots under control conditions (1 mM [Ca²⁺]_ext) or 0 mM [Ca²⁺]_ext treatment. (B) Intracellular stages of endocytosis in L. chinensis roots. The dotted rectangles highlight typical endocytosis steps
