Abstract

We have calibrated five different molecular clocks for circulating poliovirus based upon the rates of fixation of total substitutions (Kt), synonymous substitutions (Ks), synonymous transitions (As), synonymous transversions (Bs), and nonsynonymous substitutions (Ka) into the P1/capsid region (2,643 nucleotides). Rates were determined over a 10-year period by analysis of sequences of 31 wild poliovirus type 1 isolates representing a well-defined phylogeny derived from a common imported ancestor. Similar rates were obtained by linear regression, the maximum likelihood/single-rate dated-tip method, and Bayesian inference. The very rapid Kt[(1.03 ± 0.10) × 10−2 substitutions/site/year] and Ks[(1.00 ± 0.08) × 10−2] clocks were driven primarily by the Asclock [(0.96 ± 0.09) × 10−2], the Bsclock was ∼10-fold slower [(0.10 ± 0.03) × 10−2], and the more stochastic Kaclock was ∼30-fold slower [(0.03 ± 0.01) × 10−2]. Nonsynonymous substitutions at all P1/capsid sites, including the neutralizing antigenic sites, appeared to be constrained by purifying selection. Simulation of the evolution of third-codon positions suggested that saturation of synonymous transitions would be evident at 10 years and complete at ∼65 years of independent transmission. Saturation of synonymous transversions was predicted to be minimal at 20 years and incomplete at 100 years. The rapid evolution of the Kt,Ks, and Asclocks can be used to estimate the dates of divergence of closely related viruses, whereas the slower Bsand Kaclocks may be used to explore deeper evolutionary relationships within and across poliovirus genotypes.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The capsid-encoding region of poliovirus, with a rate of fixation of total substitutions in the order of 10−2 substitutions/site/year, appears less genetically stable than the region encoding non-structural proteins.

    “However, the capsid-encoding region, with a rate of fixation of total substitutions in the order of 10−2 substitutions/site/year, appears less genetically stable than the region encoding non-structural proteins [17,18].”

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.
