[Changes in pigment-protein composition of maize subchloroplast fragment fragments under conditions of phosphorylation].

The pigment-protein composition of two mesophyl chloroplast fractions from maize inbred lines II 346 and F 7 and its alterations under phosphorylation have been studied. In virtue of differences in the composition of photosystem II (PS II) and PS II light-harvesting chlorophyll a/b-protein complex (LHC II) it has been shown that fraction 70,000 g origins from grana marginal regions and fraction 100,000 g is from stroma lamellae. Migration of LHC II occurs both in marginal and stromal fractions but PS II migration, only in marginal fractions. There are some differences in peculiarities of these processes between the two maize inbred lines which can be determined genetically.
