These were used for a comprehensive analysis of molecular divergence in the system.
According to our phylogenetic analysis and molecular divergence estimation results, China is speculated to be the most probable centre.
We repeated this analysis for molecular divergence and, although the adaptors and modulators also show the lowest dN/dS values among the five main functional categories, these differences were not statistically significant (Additional file 1, Table S2).
The topology obtained from our molecular divergence dating in the BEAST analysis is generally the same as that found by previous studies based on molecular data (e.g. [ 41, 51, 145]): Lepidosauria is monophyletic, Gekkota is the sister taxon to all other Squamata, amphisbaenians are nested within Lacertoidea, and Iguania is sister group to Serpentes + Anguimorpha.
As a result, the estimated distribution of molecular divergence times is broadly consistent with quantitative analysis of the North American fossil record and traditional morphological views.
Our analysis shows a general increase in the molecular divergence of COI with taxonomic rank, a trend that suggests that morphological taxonomy is roughly in agreement with DNA evolution.
Using integrative biology approach involving molecular phylogenies, consensus sequence comparisons, signature determination, substitution rate estimations and divergence analysis, we propose a model for the evolutionary history of the AGO family of proteins in plants.
The results of functional divergence analysis provided statistical evidence for shifted evolutionary rate after gene duplication.
A high degree of molecular divergence in ITS and 28S sequences supports specific status of H. pinicola.
