Biogeography and Adaptive evolution of Streptomyces Strains from saline environments.

ABSTRACT: The genus Streptomyces is a widespread genus within the phylum Actinobacteria and has been isolated from various environments worldwide. However, little is known about whether biogeography affects distributional pattern of Streptomyces in salty environments. Such information is essential for understanding the ecology of Streptomyces. Here we analyzed four house-keeping genes (16S rRNA, rpoB, recA and atpD) and salty-tolerance related genes (ectA-ectD) of 38 Streptomyces strains isolated from saline environments in Yunnan and Xinjiang Provinces of western China. The obtained Streptomyces strains were classified into three operational taxonomic units, each comprising habitat-specific geno- and ecotype STs. In combination with expressional variations of salty-tolerance related genes, the stat
