Coordinated Movement of Two Plastid Bodies Connected by a Stromule in a Hypocotyl Cell of Transgenic Tobacco Plants Carrying a Plastid-Targeted GFP Expressed from a Nuclear Transgene Carrying a Double 35S Promoter and the recA Transit Sequence on S65T GFP (Köhler et al., 1997).

GFP fluorescence is shown as green and chlorophyll autofluorescence as red. Images are single snapshots from the Supplemental Movie 5 online. The 488-nm line of an argon laser was used to excite GFP and chlorophyll. Bar = 10 μm.

(A) and (B) The two plastid bodies indicated with arrows begin moving together to the right.

(C) and (D) Position of the two plastid bodies shown in (A) and (B) after 43 s.
