Inferring rooted species trees from unrooted gene trees using approximate Bayesian computation

摘要

Graphical abstractDisplay OmittedHighlights?A new method of species tree inference is proposed.?The method uses unrooted gene tree topologies as input and returns a rooted species tree.?The method is based on Approximate Bayesian Computation.?The method is applied to the rooting of the angiosperms.AbstractMethods for inferring species trees from gene trees motivated by incomplete lineage sorting typically use either rooted gene trees to infer a rooted species tree, or use unrooted gene trees to infer an unrooted species tree, which is then typically rooted using one or more outgroups. Theoretically, however, i
