title: Control factor of nuclear cycles in cilate conjugation: cell-to-cell transfer in multicellular complexes.
abstract: Multicellular complexes of Blepharisma intermedium are regularly produced by treating doublet cells with the gamone of complementary mating type. Cells remain united without undergoing nuclear cycles of conjugation. However, if a cell of complementary mating type unites, nuclear cycles begin at the site of this union and propagate all through the multicellular complex.
