A single open reading frame (ORF) encoding cytochrome c oxidase subunit I and II (cox1/2) was identified in the mitochondrial genome of the slime mold Dictyostelium discoideum. The cox1 coding region shares intron positions with its counterparts in fungi and algae. Northern blot analysis, using exon and intron-specific probes, suggests that the cox1/2 gene is transcribed as part of a large, eff...

A countrywide survey in Oman revealed Middle Eastrespiratory syndrome coronavirus (MERS-CoV) nucleicacid in five of 76 dromedary camels. Camel-derivedMERS-CoV sequences (3,754 nucleotides assembled from partial sequences of the open reading frame (ORF)1a, spike, and ORF4b genes) from Oman and Qatar were slightly different from each other, but closely related to human MERS-CoV sequences from the...

Tomato golden mosaic virus (TGMV) belongs to the geminivirus subgroup that is characterized by a split genome consisting of two single-stranded circular DNAs. The TGMV A genome component encodes the virus coat protein as well as all of the functions necessary for viral DNA replication. Analysis of the nucleotide sequence indicates that the TGMV A component has, in addition to the coat protein e...

Open reading frame (ORF) O and ORF P partially overlap and are located antisense to the gamma(1)34.5 gene within the domain transcribed during latency. In wild-type virus-infected cells, ORF O and ORF P are completely repressed during productive infection by ICP4, the major viral transcriptional activator/repressor. In cells infected with a mutant in which ORF P was derepressed there was a sign...

The genome of a novel human papillomavirus (HPV-82) was cloned from a vaginal intraepithelial neoplasia grade I. In our series of 291 biopsy specimens, HPV-82 was identified in one case each of cervical intraepithelial neoplasia grade II and grade III by blot hybridization. The histological localization of HPV-82 DNA in the three lesions was confirmed by in situ hybridization. The results indic...

The fin0 gene of R100 was isolated from the Fin0+ transducing phage VA lambda 57. The limits of the gene were determined by BAL31 digestions and by analysis of deletion mutations derived from an internal restriction site. The DNA sequence contained an open reading frame of 558 nucleotides that would encode a protein of 21,268 daltons. Synthesis of such a protein was observed only when the fragm...

Among the 10(5) LINE-1 sequences (L1Hs) in the human genome are one or more 6-kb segments that are active retrotransposons. Expression of these retrotransposons appears to be favored in cells of germ line origin, as well as in some other tumor cells of epithelial origin. In such cells, the product of the first L1Hs open reading frame (ORF), a protein called p40, is detectable; p40 has no appare...
