Fig. 1From: Genome analysis of the freshwater planktonic Vulcanococcus limneticus sp. nov. reveals horizontal transfer of nitrogenase operon and alternative pathways of nitrogen utilizationPhylogenomics of Vulcanococcus limneticus sp. nov. Two hundred fifty-nine conserved proteins were used to generate a maximum-likelihood phylogenetic tree with Synechococcus and Cyanobium representatives from marine, brackish, euryhaline and freshwater habitats together with the novel V.limneticus sp. nov. Prochlorococcus genomes were also added into the phylogenyBack to article page
