Characterization of the chlamydomonas flagellar collar

Research output: Contribution to journalArticlepeer-review

The flagella of Chlamydomonas reinhardtii protrude through the cell wall via short, tunnel‐like openings that are lined with 11 nm × 500 nm fibers arranged in parallel array. These cylindrical collections of fibers presumably permit free movement of the flagella within the cell wall. In this report electron‐microscopic evidence is presented showing that during the initial stages of the mating reaction intact collars slip off of the ends of the flagella when cell wall loss occurs. Electrophoretic analysis of isolated collars reveals one major protein and several minor species.
