Figure 1From: Genome based analysis of type-I polyketide synthase and nonribosomal peptide synthetase gene clusters in seven strains of five representative Nocardia speciesPhylogenetic positions of Nocardia strains studied in the present work. The phylogenetic tree was constructed using 16S rRNA gene sequences of type strains (http://www.bacterio.cict.fr/, http://www.ncbi.nlm.nih.gov/nuccore). MEGA5 software [34] was used to draw non-rooted neighbor-noining phylogenic tree. Positional information of Mycobacterium tuberculosis (Genbank accession # X58890) and Streptomyces coelicolor (#AB184196) was added to the tree. Bootstrap values of 1000 re-samplings are shown only for the main branches. The five species studied in the present work were marked with red arrows.Back to article page
