By using fluorescent isothiocyanate-conjugated concanavalin A (FITC-Con A), cell surface events were examined under a light microscope during the early period of the conjugation process in Tetrahymena thermophila. Until the two complementary mating types (D-III and IV) were mixed, Con A-binding activities were hardly detected on the cell surface of ciliates. After mixing, however, the FITC-Con A (25 μg/ml) bound especially to the anterior cell surface at the early stage of conjugation, followed by characteristic changes of the Con A-binding pattern and, subsequently, by formation of a bright fluorescent ring around the area of contact between conjugants. Such alterations of FITC-Con A-binding pattern were found to be interrupted or eliminated by cycloheximide (2 μg/ml). These findings are related to the onset and subsequent conjugation in T. thermophila.
