During the mating reaction in Chlamydomonas reinhardtii mating type plus and mating type minus gametes adhere to each other via adhesion molecules on their flagellar surfaces. This adhesive interaction induces a sexual signal leading to release of a cell wall degrading enzyme, lysin, that causes wall release and degradation. In this article, we describe the(More)
During fertilization in the biflagellated alga, Chlamydomonas reinhardtii, gametes of opposite mating types adhere to each other via agglutinin molecules located on their flagellar surfaces, generating a sexual signal that induces several cellular responses including cell wall release. This cell contact-generated signal is mediated by cAMP and release of(More)
A flagellar adhesion-induced signal sent during the mating reaction of the biflagel-late alga, Chlamydomonas reinhardtii, initiates release of cell-wall-degrading enzymes, activation of mating structures, and cell fusion. The nature of this signal is unknown, but it may be mediated by an adhesion-induced change (activation) of flagellar tips. The studies(More)
