Figure 6From: Comparative genomic analysis of carbon and nitrogen assimilation mechanisms in three indigenous bioleaching bacteria: predictions and validationsPhylogenetic tree based on NifA protein sequences. The tree was inferred using the Neighbor-Joining method, with 1000 replicates. Only those branches that appear in more than 50% of the boostrap replicates are considered. Evolutionary distances were computed using the JTT matrix. Analysis was conducted using the software MEGA4 [110].Back to article page
