Abstract
CERTAIN stocks of Paramecium contain cytoplasmic particles called kappa1. Kappa-bearing Paramecia (killers) are capable of killing other Paramecia (sensitives) and are resistant to the toxic agent which they produce1. The killer trait requires both the cytoplasmic particles and the dominant K gene for the maintenance of kappa, and is one of the most extensively studied examples of nucleocytoplasmic relations on a biological level2–5.
