Figure 5From: Sulfate assimilation in eukaryotes: fusions, relocations and lateral transfersMaximum likelihood phylogenetic tree of SiR and NiR. The outgroup contains alignable sequences from proteobacteria that reduce both sulfite and nitrite. Numbers at nodes are (left to right) Bayesian posterior probabilities, maximum likelihood bootstraps and distance bootstraps. Support for nodes with less that 60 bootstraps by both methods are not show. Where tree topology differed or bootstraps by one method are less than 60, a dash is shown. A filled circle indicates the presence of a plastid targeting presequence; an open circle indicates a mitochondrial targeting presequence; a filled star indicates an N terminal pyruvate ferredoxin oxidoreductase moiety. The bar indicates the number of amino acid changes per branch length.Back to article page
