Figure 2. Optical trapping of the amyloplasts in endodermal cells of Arabidopsis inflorescence stems. A. Diagram of the endodermal cells. ep=epidermis; co=cortex; en=endodermis; st=stele; A=amyloplasts; N=nucleus; V=vacuole. B. Schematic illustration of optical trapping of the amyloplasts. C–F. Time-lapse images of amyloplast movements and trajectories of the representative amyloplasts before (white arrowheads, C and D) and during laser irradiation (yellow arrowheads, E and F). Autofluorescence of the amyloplasts (upper panels) and bright-field images (lower panels) are shown (C and E). Dashed circles denote the laser focus of the trapping laser (E). Dashed lines=outline of the endodermal cell; red and blue dots=the position of the amyloplast at 0 and 120 s, respectively (D and F). Scale=2 µm.
