Immunoelectrophoretic analysis of the whole cell extract of Chlamydomonas reinhardtii by using the antiserum against the wild strain (21gr) demonstrated at least 14 antigenic components. When 11 mutants were compared with the wild strain, a certain difference in pattern was found in the number and the intensity of the precipitin lines Of the 14 immune-precipitin lines in the wild strain, 8 were common to all the strains tested, and the remaining 6 were variable according to the strain. The present data suggest the division of C. reinhardtii into some immunologically related groups.The correspondence of the immunoelectrophoretic pattern to the genetically marked strain was examined. However, there was no indication of the association of antigenic specificities with any identified mutant characters. Any immunological differences in the mating type could not be found, either. However, the 2:2 segregation for the formation of some of the immune-lines suggests that these may be a single Mendelian character.
