Rearrangements of microfilaments are associated with changes in stromule morphology A-F) Time-lapse images of a plastid and stromule in dark-grown hypocotyl epidermis taken at 15 second intervals. GFP-hTalin-labeled MFs are false-colored red. DIC images are false-colored green. G-L) Outlines of plastids (colored) and MFs (gray) from images in A-F, respectively, showing stromule-MF interactions. Arrows denote intersection of MFs and stromule-deformation point (See Results). Arrowheads denote the plastid body. Bar: 5 μm.
