Communlications Molecular Integrity of Chloroplast Ribosomal

چکیده
We have previously shown (Leaver & Ingle, 1971) that the heavier of the two high-molecular-weight chloroplast rRNA components (1. x 106 mol.wt.) from a variety of plants is unstable under normal conditions of extraction and fractionation. In contrast, the light chloroplast rRNA (0.56 x 106 mol.wt.) remains intact under similar conditions. It seems likely that cleavage of the rRNA chain occurs after transcription, either in the tissue or during isolation of the RNA, as the cleavage products

The Phylogeny of Calligonum and Pteropyrum (Polygonaceae) Based on Nuclear Ribosomal DNA ITS and Chloroplast trnL-F Sequences
This study represents phylogenetic analyses of two woody polygonaceous genera Calligonum and Pteropyrum using both chloroplast fragment (trnL-F) and the nuclear ribosomal internal transcribed spacer (nrDNA ITS) sequence data. All inferred phylogenies using parsimony and Bayesian methods showed that Calligonum and Pteropyrum are both monophyletic and closely related taxa. They have no affinity w...
متن کاملPhylogeny of Ononis in Iran using nuclear ribosomal DNA and chloroplast sequence data
The genus Ononis,embraces more than 85 species worldwide. In the present study, materials of two subspecies of O. spinosa from different localities of Iran alongside some other native species of the genus were included in phylogenetic analyses. In addition, over 50 accessions were obtained from GenBank. In order to clarify the exact number of subspecies of O. spinosa in Iran, datasets were obta...
متن کاملImmunological similarities between specific chloroplast ribosomal proteins from Chlamydomonas reinhardtii and ribosomal proteins from Escherichia coli.
Polyclonal antibodies were elicited against seven of the 33 different proteins of the large subunit of the chloroplast ribosome from Chlamydomonas reinhardtii. Three of these proteins are synthesized in the chloroplast and four are made in the cytoplasm and imported. In western blots, six of the seven antisera are monospecific for their respective large subunit ribosomal proteins, and none of t...
متن کاملChloroplast ribosomal proteins of Chlamydomonas synthesized in the cytoplasm are made as precursors
Polyadenylated RNA from Chlamydomonas was translated in a cell-free rabbit reticulocyte system that employed [35S]methionine. Antibodies made to four chloroplast ribosomal proteins synthesized in the cytoplasm and imported into the organelle were used for indirect immunoprecipitation of the labeled translation products, which were subsequently visualized on fluorographs of SDS gels. The cytopla...
متن کاملStudies on the Protein Moiety of Plant Ribosomes
The approximate number and molecular weight of pea seedling ribosomal proteins were determined by twodimensional electrophoresis on polyacrylamide gels containing either urea or sodium dodecyl sulfate. The small (40 S) ribosomal subunit contained 32 to 40 proteins and the large (60 S) subunit 44 to 55 proteins. The great majority of ribosomal proteins were basic and had molecular weights betwee...
