title: [Incompatibility during transplantation of nuclei in amoeba. IV. Transplantation compatibility in different strains of Amoeba proteus].
abstract: Seven laboratory Amoeba proteus strains of different origin were tested for their transplantation compatibility (i.e. viability of artificially produced heterokaryons) in all possible pair combinations. Incompatible combinations (14) as well as completely compatible ones (7) were found. Compatibility was distributed among strain combinations non-randomly. All the strains studied could be classified into three groups with respect to compatibility ("compatibility groups") involving 1, 2 and 4 strains, respectively. Within the third group any pair of strains was compatible, as well as both strains of the second group. On the contrary, any strains from different groups were always incompatible. Possible nature of the compatibility groups is discussed. It is suggested that they might be analogous to syngens of Ciliates.
