Sentence examples for between multiple gene trees from inspiring English sources
Consequently, these few examples stress the value in systematics of developing phylogenetic approaches aimed at testing multiple relationships, possible and impossible alike: accounting both for the limited as well as for the conflictual resolutions between multiple gene trees.
This scenario, whereby multiple gene trees consistently resolve the phylogeny between but not within species, is the basis for the Phylogenetic Concordance Species Concept advocated by Taylor et al. [34].
For phylogenetic purposes, it would be desirable to consider multiple gene trees based on chloroplast and nuclear genomes, because independently derived gene trees may not be congruent (Schaal et al. 1998).
Multiple gene trees are often then exploited because interestingly, in each gene tree, some nodes may in fact receive significant support.
TreeBeST searches for an optimal gene tree given a species tree, by first inferring multiple gene trees, including trees derived from neighbor-joining and PhyML under multiple models of evolution, as well as trees that make no use of the sequence information, but simply minimize gene duplications and losses based on a user-supplied species tree (we used the species trees in figs. 2 B and 3).
Consequently, the comparison of multiple gene trees is the only way to get a central tendency which could be interpreted as the species tree [ 61- 63].
This method coestimates simultaneously multiple gene trees embedded in a shared species tree, specifying ancestral relationships (topology), and the times ancestral species separated (divergence times).
We are currently working on an extension of this work to the estimation of a species tree from multiple gene trees.
A Bayesian hierarchical model has been proposed to reconstruct the species tree by incorporating information from multiple gene trees [ 49, 50].
