ligotree: Maximum likelihood tree for 13 Ligophorus species

Description

This data set contains the maximum likelihood (Felsenstein, 1981) phylogenetic tree of 13 Ligophorus species, inferred using concatenated 18S rRNA, ITS1 rRNA and 28S rRNA DNA sequences (10 000 bootstrap replicates). The best DNA substitution model was GTR+G. Multiple sequence alignment was done using online MAFFT server (Version 7; Katoh, 2013; Katoh & Standley, 2013) with default parameters. Maximum likelihood tree construction was done using IQ-TREE (Minh et al., 201; Nguyen et al., 2015).

Usage

data(ligotree)

Format

A phylo object, so the ape package (Paradis et al., 2004) needs to be installed

Details

The phylogenetic tree comes with bootstrap support for the internal nodes.
