The structure, functions, and evolution of cellular organelles are reviewed. The mitochondrial genomes of eukaryotes differ considerably in size and structural organization mainly due to the length variation in noncoding regions and the presence of introns. The mitochondrial genomes of angiosperms are the largest and most complicated. Gene content in(More)
The chloroplast genome is highly condensed and packed into discrete structures called "nucleoids". Each pea chloroplast contains 16-20 spherical nucleoids randomly located in the matrix of organelle. Nucleoids are shown to contain DNA, RNA and proteins (1:0.62:2.3). Approximately 30 polypeptides (mol. masses 94 to 12 kD) have been found in nucleoids.(More)
The data on the structure and functions of the mitochondrial genomes of protists (Protozoa and unicellular red and green algae) are reviewed. It is emphasized that mitochondrial gene structure and composition, as well as organization of mitochondrial genomes in protists are more diverse than in multicellular eukaryotes. The gene content of mitochondrial(More)
It is proven that retrograde tetrapyrrole-induced plastid signals, light signals, and signals induced by hormones and carbohydrates influence expression of nuclear genes of plastid stress ELIP in Arabidopsis thaliana L. Plastid signals differently regulated expression of genes from multigene family of photosynthesis proteins (ELIP and Lhcb2) and were(More)
Basic proteins were isolated from purified pea chloroplast nucleoids by acid extraction. Using RP-HPLC, the component composition of the basic proteins was studied. SDS-PAGE of major HPLC-fractions showed that the basic nucleoid proteins are heterogeneous with mol. masses of components from 17 to 30 kDa. One polypeptide with mol. mass of 28 kDa (P28) was(More)
Ribosomal proteins from chloroplasts of Nicotiana tabacum L. (cv. Petit Havana) and of SRl, a mutant derived from it, with uniparentally inherited streptomycin resistance, were characterised by two-dimensional gel electrophoresis. From the 67 proteins identified, one has an altered electrophoretic mobility when isolated from the mutant. Streptomycin(More)
The data on the structure and gene composition in completely sequenced plastid (predominantly chloroplast) genomes of higher plants and algae are reviewed. In higher plants, genome structure and gene composition are highly conserved. Plastid genomes of algae are less conserved and contain several unique genes, which are not found in chloroplast DNAs of(More)
The review summarizes the current understanding of light-inducible proteins of plants, wide-spread among prokaryotic and eukaryotic photosynthetic organisms. The greatest attention is paid to the Early light-inducible proteins of plastids (Elip) and their photoprotective role under light stress. Data are presented on structure and functions of Elip-related(More)
Ribosomes and ribosomal proteins from wild-type and a yellow mutant of Chlamydomonas reinhardii were analysed and compared by two-dimensional gel electrophoresis. Mixothrophycally grown yellow-27 mutant differs from wild-type cells in lowered chlorophyll content and grana fromation of the chloroplast. Analytical ultracentrifuge analyses of cell extracts(More)
