Phylogenomic analysis of Nicotiana gene clusters. Bar chart showing the number of Nicotiana genes that were present in a set of pre-defined phylogenetic tree topologies. Genes from the N. tabacum, N. sylvesteris and N. tomentosiformis assemblies were clustered and phylogenetic trees for each cluster were generated by Maximum Likelihood (ML; black bars) and Neighbour Joining (NJ; open bars) methods using S. lycopersicum as an out-group. The different tree topologies are shown along the x-axis with N. tabacum (A; Ntab) N. sylvesteris (B; Nsyl), N. tomentosiformis (C; Ntom) and S. lycopersicum (Slyc) genes represented in text and/or dendrogram form.
