Extract

The first paper of this symposium was presented by Y. Tsukii (Hosei, Univ.) under the title of ‘Genes controlling the specificity of mating type and matingtype-substance interactions in Paramecium.’

Sexual reproduction in the ciliate Paramecium caudatum is initiated by ciliary agglutination (mating reaction) between cells of complementary mating types, E and O. This initial cell contact involves specific macromolecules called the ‘mating-type substances’, proteins associated with ciliary membranes. Although they have eluded all attempts at isolation, genetic approaches are disclosing their structural characteristics.
