Both yeast W double-stranded RNA and its single-stranded form 20S RNA are linear.
Most yeast strains carry a cytoplasmic double-stranded RNA (dsRNA) molecule called W, of 2.5 kb in size. We have cloned and sequenced most of W genome (1), and we proposed that W (+) strands were identical to 20S RNA, a single-stranded RNA (ssRNA) species, whose copy number is highly induced under stress conditions. Recently it was proposed that 20S RNA was circular (2). In this paper, however,...
متن کاملPlant virus-derived small interfering RNAs originate predominantly from highly structured single-stranded viral RNAs.
RNA silencing is conserved in a broad range of eukaryotes and includes the phenomena of RNA interference in animals and posttranscriptional gene silencing (PTGS) in plants. In plants, PTGS acts as an antiviral system; a successful virus infection requires suppression or evasion of the induced silencing response. Small interfering RNAs (siRNAs) accumulate in plants infected with positive-strand ...
متن کاملRecombination in Eukaryotic Single Stranded DNA Viruses
Although single stranded (ss) DNA viruses that infect humans and their domesticated animals do not generally cause major diseases, the arthropod borne ssDNA viruses of plants do, and as a result seriously constrain food production in most temperate regions of the world. Besides the well known plant and animal-infecting ssDNA viruses, it has recently become apparent through metagenomic surveys o...
متن کاملConformational change of single-stranded RNAs induced by liposome binding
The interaction between single-stranded RNAs and liposomes was studied using UV, Fourier Transform Infrared spectroscopy (FTIR) and Circular Dichroism spectroscopy (CD). The effect of the surface characteristics of liposomes, which were composed of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) and modified with cholesterol (Ch) or 1,2-dioleoyl-3-trimethylammonium propane (DOTAP), on t...
متن کاملsingle-stranded phage DNA rings encapsidated in the coat proteins forming mature virus and RFII molecules entering a new round of single-stranded DNA
Accumulation of replicative intermediates of the bacteriophage 0X174 was observed in E.coli C infected cells when phage DNA methylation has been inhibited by nicotinamide or when cells were infected with a temperaturesensitive mutant in gene A. Analysis of the accumulating replicative intermediates by electron microscopy revealed that these molecules are composed of double--stranded DNA rings w...
