Full abstract
The analysis of a group of recombinant strains of phenotypically yellow mutant Y-4 Chlamydomonas reinhardii has shown a considerable variability in displaying the degree of pigmentation. Chlorophyll "a" is the first to accumulate in chloroplasts. Chlorophyll "b" was found in strains when the content of chlorophyll "a" reached 1% of its concentration in cells of the wild type, The occurrence of spectral forms of chlorophyll "a" at 661, 667, 678, 685, 698 and 703 does not correlate with its quantitative accumulation. Variability in pigment accumulation is accompanied by changes both in the structural organization of the membrane system of chloroplasts and in the functional activity of photosystems. The degree of development of chloroplast structure in the group of recombinant strains varies from the formation of vesicules to well developed tilakoids and their arrangement in grains.
