title: [Ultrastructural organization and composition of carotenoids in the eyespot in the mutant Chlamydomonas reinhardtii].
abstract: Biogenesis of the ultrastructure of the eyespot in the chloroplasts of unicellular green algae Chlamydomonas reinhardtii has been studied. We have found that the development of the structure of the eyespot correlates with the accumulation of carotenoids. Depending on their accumulation, the eyespots form from 1 to 4 lines of lipid-carotenoid globules. It has been shown that only carotenes are accumulated in the globules of the eyespots. We first have found that the composition of carotenes in the eyespots of the mutants may vary due to the changes in their composition in the membranes of chloroplasts.
