Movies showing IFT and protein transport in flagella of Chlamydomonas reinhardtii
Intraflagellar transport (IFT)
IFT20-mCherry expressed in ift20-1 null mutant imaged by TIRFM in real time.
Tubulin transport by IFT
Simultaneous imaging of mNeonGreen-tagged alpha-tubulin (left) and IFT20-mCherry (right) in a cell with growing cilia.
Tubulin transport in growing cilia
Cilia were amputated from sfGFP-tubulin expressing cell and the cell was allowed to partially regrow the cilia prior to TIRF analysis. Then, both cilia were bleached and the reentry of unbleached GFP-tubulin from the cell body was imaged. Note tubulin transport by IFT and incorporation of tubulin into the distal parts of the growing cilia.
