Plastids and mitochondria have many protein complexes that include subunits encoded by organelle and nuclear genomes. In animal cells, compensatory evolution between mitochondrial and nuclear-encoded subunits was identified and the high mitochondrial mutation rates were hypothesized to drive compensatory evolution in nuclear genomes. In plant cells, compensatory evolution between plastid and nu...
Control of ribosome biogenesis is a potential mechanism for the regulation of cell size during growth, and a key step in regulating ribosome production is ribosomal RNA synthesis by RNA polymerase I (Pol I). In humans, Pol I transcription requires the upstream binding factor UBF and the selectivity factor SL1 to assemble coordinately on the promoter. UBF is an HMG box-containing factor that bin...
We describe the structure (3840 bp) of a novel Euglena gracilis chloroplast ribosomal protein operon that encodes the five genes rpl16-rpl14-rpl5-rps8-rpl36. The gene organization resembles the spc and the 3'-end of the S10 ribosomal protein operons of E. coli. The rpl5 is a new chloroplast gene not previously reported for any chloroplast genome to date and also not described as a nuclear-encod...
The development of organelle-specific fluorescent probes has been impeded by the absence a comprehensive understanding relationship between physicochemical properties and their selectivity towards specific organelles. Although few machine learning models have suggested several parameters that control target organelle attempted to predict organelles, they challenged low accuracy limited range ap...
background: the present study was carried out to detect the infection of larval stages of trichobilharzia species in the snail lymnaea auricularia in northwestern iran based on dna analysis. methods: a total number of 320 snails of l. auricularia were sampled from four water-bodies located in the suburb of urmia city, north west iran, during may to november 2011. the snails were first microscop...
The effect of chloramphenicol (CAP) on cell division and organelle ultrastructure was studied during light-induced chloroplast development in the Chrysophyte alga, Ochromonas danica. Since the growth rate of the CAP-treated cells is the same as that of the control cells for the first 12 hr in the light, CAP is presumed to be acting during that interval solely by inhibiting protein synthesis on ...
The ribosome is an evolutionarily conserved organelle essential for cellular function. Ribosome construction requires assembly of approximately 80 different ribosomal proteins (RPs) and four different species of rRNA. As RPs co-assemble into one multi-subunit complex, mutation of the genes that encode RPs might be expected to give rise to phenocopies, in which the same phenotype is associated w...
