Extensive variation in evolutionary rate of rbcL gene sequences among seed plants.
Open accessAbstract
Extensive variation in synonymous and nonsynonymous rates of substitution was observed among 50 sequences of the gene coding for the large subunit of ribulose-1,5-bisphosphate carboxylase (rbcL) representing bryophyte, conifer, dicot, and monocot taxa. Relative rate tests revealed rate differences of up to 138% for nonsynonymous substitutions and up to 85% for synonymous ones. Within angiosperms, the annual forms evolved more rapidly, on average, than perennial forms. This rate heterogeneity was more extensive at nonsynonymous sites than synonymous ones, and it resulted primarily from a recent acceleration of substitution rate in many groups of angiosperms.

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.
