Interrelationships between microtubules, a striated fiber, and the gametic mating structure of Chlamydomonas reinhardi.

Abstract

The microtubule system associated with the Chlamydomonas reinhardi flagellar apparatus is shown to differ from previous descriptions; two of the four flagellar "roots" possess only two microtubules and are associated with a finely striated fiber. In gametic cells this fiber underlies the gametic mating structure and makes contact with it. Functional interpretations are offered.
