FIG. 7.

UPGMA dendrogram constructed from similarity matching data (Dice-Sorensen index) for all T-RFLP fragments (5′ and 3′ T-RF frequencies generated after AluI and CfoI digestion) of 16S rDNA amplified from soil and generated by using MVSP version 3.12h. The mean and standard deviation number of T-RFs analyzed was as stated in the legend to Fig. 6. The scale bar represents percent similarity.
