A survey of wild-rodent populations has revealed that murine norovirus (MNV) is present and diverse in wild-house mice Mus musculus. This virus is genetically similar to MNV infecting show mice and previously described variants circulating in laboratory mice. The detection of MNV in wild-mouse populations suggests that MNV infection of laboratory mice and show mice (from which laboratory mice a...
Litchi downy blight, caused by Peronophythora litchii, is one of the major diseases of litchi and has caused severe economic losses. P. litchii has the unique ability to produce downy mildew like sporangiophores under artificial culture. The pathogen had been placed in a new family Peronophytophthoraceae by some authors. In this study, the whole transcriptome of P. litchii from mycelia, sporang...
Comparisons of the 6213 predicted Saccharomyces cerevisiae open reading frame (ORF) products with sequences from organisms of other biological phyla differentiate genes commonly conserved in evolution from 'maverick' genes which have no homologue in phyla other than the Ascomycetes. We show that a majority of the 'maverick' genes have homologues among other yeast species and thus define a set o...
Upstream open reading frames (uORFs) are known to regulate a few specific transcripts, and recent computational and experimental studies have suggested candidate uORF regulation across the genome. In this issue, Johnstone et al (2016) use ribosome profiling to identify translated uORFs and measure their effects on downstream translation. Furthermore, they show that regulatory uORFs are conserve...
Endornaviruses have large double-stranded RNA (dsRNA) genomes that carry a single open reading frame (ORF). Here we report the complete genome of a novel endornavirus, assembled from next-generation sequence data generated from Vitis vinifera-extracted dsRNA. Two different fungal hosts have been identified for this virus, suggesting that horizontal transmission of the virus is possible.
Resources from the Sinorhizobium meliloti Rm1021 open reading frame (ORF) plasmid libraries were used in a medium-throughput method to construct a set of 50 overlapping deletion mutants covering all of the Rm1021 pSymA megaplasmid except the replicon region. Each resulting pSymA derivative carried a defined deletion of approximately 25 ORFs. Various phenotypes, including cytochrome c respiratio...
Phylogenetic analysis has become essential in researching the evolutionary relationships between viruses. These relationships are depicted on phylogenetic trees, in which viruses are grouped based on sequence similarity. Viral evolutionary relationships are identified from open reading frames rather than from complete sequences. Recently, cloud computing has become popular for developing intern...
The complete extent to which the human genome is translated into polypeptides is of fundamental importance. We report a peptidomic strategy to detect short open reading frame (sORF)-encoded polypeptides (SEPs) in human cells. We identify 90 SEPs, 86 of which are previously uncharacterized, which is the largest number of human SEPs ever reported. SEP abundances range from 10-1,000 molecules per ...
A human astrovirus (HAstV) strain from Kenya was characterized by nucleotide sequence analysis. Sequences from open reading frame 1a (ORF1a) clustered with genotype 6/7, those from ORF1b clustered with genotype 3, and those from ORF2 clustered with genotype 2. A recombination point in the ORF1b-ORF2 junction was identified, with a second possible recombination point within the ORF1a region.
Successful replication and transmission of large DNA viruses such as the cytomegaloviruses (CMV) family of viruses depends on the ability to interfere with multiple aspects of the host immune response. Apoptosis functions as a host innate defence mechanism against viral infection, and the capacity to interfere with this process is essential for the replication of many viruses. The Bcl-2 family ...
