[Spectral forms of the chlorophyll of mutants of Chlamydomonas with inactive photosystems].

Investigations of non-photosinthesizing mutants of Chlamydomonas reinhardii with damaged activity of both or one of the photosystems have shown that the chlorophyll a form with the absorption maximum at 685 nm and low temperature fluorescence band at 696 nm is a part of the pigment-protein complex of PS-2. Chlorophyll a forms with absorption maxima at 689, 698 and 703 nm belong to the pigment-protein complex of PS-1. They seem to be responsible for the long-wave band of chlorophyll fluorescence with the maximum at 707--718 nm. Chlorophyll a forms with absorption at 661, 667 and 678 nm and a short-wave fluorescence band at 685--690 nm rank among the pigments of the light-converging complex, as well as chlorophyll b with the absorption maximum at 644 and 649 nm.
