Genetic consequences of packaging two RNA genomes in one retroviral particle: pseudodiploidy and high rate of genetic recombination.
Open accessAbstract
Retroviruses contain two complete viral genomic RNAs in each virion. A system to study in a single round of replication the products of virions with two different genomic RNAs was established. A spleen necrosis virus-based splicing vector containing both the neomycin-resistance gene (neo) and the hygromycin B phosphotransferase gene (hygro) was used. Two frameshift mutants were derived from this vector such that the neo and the hygro genes were inactivated in separate vectors. Thus, each vector confers resistance to only one selection. The vectors with frameshift mutations were separately propagated and were pooled to infect DSDh helper cells. Doubly resistant cell clones were isolated, and viruses produced from these clones were used to infect D17 cells. This protocol allowed virions containing two different genomic RNAs (heterozygotes) to complete one round of retroviral replication. The molecular nature of progeny that conferred resistance to single or double selection and their ratio were determined. Our data demonstrate that each infectious heterozygous virion produces only one provirus. The rate of retroviral recombination is approximately 2% per kilobase per replication cycle. Recombinant proviruses are progeny of heterozygous virions.

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.
