Figure 4From: Molecular evolution of glutamine synthetase II: Phylogenetic evidence of a non-endosymbiotic gene transfer event early in plant evolutionMaximum clade probability chronogram from the BEAST analysis of the GSII B and GSII E amino acid sequence alignment. All lineages were allowed to evolve according to a relaxed molecular clock and WAG + Inv + Gamma model. Bars on nodes indicate the width of the 95% highest posterior density for each divergence time.Back to article page
