Figure 1 .

UPGMA dendrogram inferred from ARDRA patterns of actinomycetes isolated from solar saltern ponds. The dendrogram shows the clustering of 69 actinomycete isolates generated from amplified ribosomal DNA restriction analysis with restriction endonuclease HaeIII, using the UPGMA algorithm and the Jaccard’s coefficient. The Roman numerals I to XII represent the twelve clusters obtained in the analysis. The ribotypes selected from sequencing analysis are highlighted in boldface. The additional isolates subjected to sequence analysis are starred.
