Phylogenetic relationships of Nostoc sp. PTV (designated by black square) inferred under the posterior probability criterion (MrBayes) from the gene for 16S rRNA, partial sequence information. Numbers at the nodes indicate the Bayesian statistical support values (posterior probabilities multiplied by 100); only values higher than 50% are given. The scale bar indicates the number of substitutions per nucleotide position.
