- Аннотация: The present series of papers is part of an integrated research program to understand the effective functional strategy of natural light-harvesting molecular antennae in photosynthetic organisms. This work tackles the problem of the structural optimization of light-harvesting antennae of variable size. In vivo, this size is controlled by light intensity during growth, thus implying more sophisticated optimization strategies, since larger antenna size demands finer structural tuning. Earlier modeling experiments showed that the aggregation of the antenna pigments, apart from being itself a universal structural factor optimizing the performance of light-harvesting antenna with any (!) spatial lattice, maintains its functioning provided that the degree of aggregation varies: the larger the unit building block, the higher the efficiency of the whole structure. It means that altering the degree of pigment aggregation in response to the antenna size is biologically expedient. In the case of the oligomeric chlorosomal antenna of green bacteria, the strategy of optimizing the variable antenna structure in response to the illumination intensity was demonstrated to take place in vivo and ensure high antenna efficiency regardless of its size, thus allowing bacteria to survive in a broad range of light intensities.
