Biogeography of actinomycete communities and type II polyketide synthase genes in soils collected in New Jersey and Central Asia.

ABSTRACT: Soil microbial communities are believed to be comprised of thousands of different bacterial species. One prevailing idea is that "everything is everywhere, and the environment selects," implying that all types of bacteria are present in all environments where their growth requirements are met. We tested this hypothesis using actinomycete communities and type II polyketide synthase (PKS) genes found in soils collected from New Jersey and Uzbekistan (n = 91). Terminal restriction fragment length polymorphism analysis using actinomycete 16S rRNA and type II PKS genes was employed to determine community profiles. The terminal fragment frequencies in soil samples had a lognormal distribution, indicating that the majority of actinomycete phylotypes and PKS pathways are present infrequently in th
