phyloSkeleton: taxon selection, data retrieval and marker identification for phylogenomics
Summary With the wealth of available genome sequences, a difficult and tedious part of inferring phylogenomic trees is now to select genomes with an appropriate taxon density in the different parts of the tree. The package described here offers tools to easily select the most representative organisms, following a set of simple rules based on taxonomy and assembly quality, to retrieve the genome...
متن کاملPerfect taxon sampling and phylogenetically decisive taxon coverage
In a recent study, Steel and Sanderson defined and characterized phylogenetically decisive sets of taxon sets. A set is called phylogenetically decisive if regardless of the trees chosen for each of its taxon sets, as long as these trees are compatible with one another, their supertree is always unique. This implies that the sampled taxon sets always lead to a unique supertree, regardless what ...
متن کاملIncreased taxon sampling greatly reduces phylogenetic error.
Several authors have argued recently that extensive taxon sampling has a positive and important effect on the accuracy of phylogenetic estimates. However, other authors have argued that there is little benefit of extensive taxon sampling, and so phylogenetic problems can or should be reduced to a few exemplar taxa as a means of reducing the computational complexity of the phylogenetic analysis....

متن کاملBroad taxon and gene sampling indicate that chaetognaths are protostomes
Despite advances in phylogenetic methods, there are still a number of enigmatic phyla whose affinities remain poorly resolved. One of the most recalcitrant of these is a group of small predatory marine invertebrates, the chaetognaths (arrow worms). Resolution of the phylogenetic position of the chaetognaths is key for reconstructing the evolutionary history of some of the most fundamental featu...
