Plant rhythms - captured live
The leaf movement video was taken using the Kujata imaging system over a period of 24 hours in 16 day old Arabidopsis seedlings. Individual images are taken 3 hours apart.
Click for a Kujata movie of ... rhythmic hypocotyl elongation (0.5 MB file), similar to Figure 1 of Mandy Dowson-Day's Plant Journal paper, 1999. Hypocotyls elongate in the subjective evening under constant light, and stop elongating in the morning.
Rhythmic CAB:luciferase expression in a young plant (in false colour) - there's another leaf intruding at the top of the picture.
Click here for a luciferase movie showing an internally desynchronised tobacco plant under constant light, with its leaves free-running at opposite phases (from Simon Thain's Current Biology paper, 2000).
Note - all the video's are sections of primary experimental data, not special "Hollywood" scenes. You are welcome to use them so long as you acknowledge their provenance.
