Biogenesis of the ultrastructure of the eyespot in chloroplasts of a unicellular green alga Chlamydomonas reinhardtii has been studied. It has been ascertained that development of the structure of the eyespot correlates with the accumulation of carotenoids. Due to their accumulation the eyespot forms from 1 to 4 lines of lipid-carotenoid globules. It has been shown that in globules of the eyespot only carotenes are accumulated. It has been found for the first time that in mutants the carotene composition in the eyespot may change due to the changes of their composition in chloroplast membranes.
对单细胞绿藻莱茵衣藻叶绿体中眼点超微结构的生物发生进行了研究。已确定眼点结构的发育与类胡萝卜素的积累相关。由于它们的积累，眼点由1至4行脂质 - 类胡萝卜素小球形成。已表明在眼点的小球中仅积累了胡萝卜素。首次发现，在突变体中，由于叶绿体膜中其组成的变化，眼点中的胡萝卜素组成可能会发生变化。
