Phylogenetic relationship of Chromatium okenii strain LaCa based on 16S rRNA gene sequences. IQTree49 was used to calculate a consensus tree combining 1,000 bootstrap iterations and 1,000 aLRT replications. Branch lengths were optimized by maximum likelihood on original alignment. Full node circles indicate bootstrap support above 60%. Scale bar denotes genomic distance in base-pair (bp) substitutions per 100 bp.
