Kappa particles were injected into stock-51 sensitives (KK) of Paramecium tetraurelia to investigate the maintenance of kappa by gene K during macronuclear reorganization. Injection into exconjugants and autogamous cells followed by macronuclear regeneration, induced by microsurgical removal of macronuclear Anlagen, resulted in maintenance of kappa particles by a considerable proportion of the clones descended from the recipient paramecia. Injection into animals that underwent normal reorganization however usually failed to yield particle-maintaining paramecia.
