title: [Spectral forms of chlorophyll and chloroplast structure of Chlamydomonas mutants with disortions in their light-gathering pigments].
abstract: A 2-3-fold reduction of chlorophyll content in pigment mutants of Chlamydomonas reinhardii is conditioned by the disturbances in light-harvesting pigments. When the activity of both photosystems is preserved, the reduction of short-wave forms of chlorophyll a (667, 678 nm) is accompanied by a fall of the fluorescence maximum at 685-690 nm; the disturbance of the long-wave forms with the adsorption maxima at 689, 698 an 703 nm results in a decrease of the chlorophyll fluorescence band at 707-718 nm. The long-wave forms of chlorophyll appertain to the pigment-protein complex of PS-1 which is not involved in the formation of contacts between the grand thylacoids.
