Abstract

We have recently introduced a novel procedure for the construction of herpesvirus mutants that is based on the cloning and mutagenesis of herpesvirus genomes as infectious bacterial artificial chromosomes (BACs) in Escherichia coli (M. Messerle, I. Crnković, W. Hammerschmidt, H. Ziegler, and U. H. Koszinowski, Proc. Natl. Acad. Sci. USA 94:14759–14763, 1997). Here we describe the application of this technique to the human cytomegalovirus (HCMV) strain AD169. Since it was not clear whether the terminal and internal repeat sequences of the HCMV genome would give rise to recombination, the stability of the cloned HCMV genome was examined during propagation in E. coli , during mutagenesis, and after transfection in permissive fibroblasts. Interestingly, the HCMV BACs were frozen in defined conformations in E. coli . The transfection of the HCMV BACs into human fibroblasts resulted in the reconstitution of infectious virus and isomerization of the reconstituted genomes. The power of the BAC mutagenesis procedure was exemplarily demonstrated by the disruption of the gpUL37 open reading frame. The transfection of the mutated BAC led to plaque formation, indicating that the gpUL37 gene product is dispensable for growth of HCMV in fibroblasts. The new procedure will considerably speed up the construction of HCMV mutants and facilitate genetic analysis of HCMV functions.

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.
