Cloning and synthesis of infectious cardiovirus RNAs containing short, discrete poly(C) tracts

Abstract

Mengovirus RNA transcripts with 5' noncoding poly(C) tracts of C8, C12, and C13UC10 have been synthesized in vitro from cDNA clones and shown to be infectious to HeLa cells. A chimeric clone has also been constructed which links the 5' end from one mengovirus clone (299 nucleotides, containing C13UC10) to a 7,424-base fragment derived from the 3' end of encephalomyocarditis (EMC) virus. Progeny virus isolated after transfection with the clone-derived RNAs had the same poly(C) tracts, mengovirus-specific sequences, or EMC virus-specific sequences as the transcript from which it was derived. Although the cloned poly(C) tracts were considerably shorter than those found in viral RNA from mengovirus (C50UC10) or EMC virus (C115UCUC3UC10), the growth characteristics of the progeny viruses in HeLa cells were indistinguishable from those of the parental viruses, indicating the length of this tract does not play a significant restrictive role for cardiovirus infectivity in tissue culture.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
