Recent molecular and cellular data on the sexual cycle of Chlamydomonas reinhardtii, a unicellular green alga, is considered in the context of current theories on the origins and evolution of eukaryotic sex. The mating-type locus of C. reinhardtii co

Cyclic AMP (cAMP) has been shown to be a primary signal of the agglutination-induced mating events of flagellar tip activation, cell wall loss, and mating structure activation in the unicellular alga Chlamydomonas reinhardtii (Pasquale and Goodenough

Cell fusion between mating type plus (mt+) and minus (mt-) gametes of Chlamydomonas reinhardtii is analyzed structurally and subjected to experimental manipulation. Cell wall lysis, a necessary prelude to fusion, is shown to require flagellar aggluti

Antisera raised against vegetative and gametic flagella of Chlamydomonas reinhardi have been used to probe dynamic properties of the flagellar membranes. The antisera, which agglutinate cells via their flagella, associate with antigens that are prese

Experimental manipulations of gametes of Chlamydomonas reinhardi and ultrastructural observation were used to examine the composition of the microfilaments in the fertilization tubule, their probable mode of formation, and their interaction with intr

The mutant strain bald-2 is unique among "flagellaless" strains of Chlamydomonas reinhardtii isolated to date, in that it possesses a mutant basal body: it is only capable of forming a ring of nine singlet microtubules, 180 nm in diameter, instead of

Gametes of Chlamydomonas reinhardi become activated for cell fusion as the consequence of sexual adhesion between membranes of mating-type plus and minus flagella. By using tannic acid plus en bloc uranyl acetate staining, and by fixing at very early

Tetrahymena and Chlamydomonas cells treated with high (0.25-0.5%) concentrations of the detergent Nonidet P-40 in appropriate buffers retain the shape of the intact cells but are devoid of any ciliary activity unless supplied with MgATP. ATP causes t

Our investigations of the mating reaction of Chlamydomonas revealed a surprisingly intricate series of interrelated events. Adhering sites are moved to the flagellar tips in a fashion highly reminiscent of the capping of surface ligands over the cent
