Abstract

Horizontal gene transfer between bacteria in soil will be investigated using the streptomycin biosynthesis and resistance gene cluster of S. griseus as a model system to determine origin, frequency, and relative timescale of transfer. The dissemination of clustered genes will be studied using strA, the resistance gene for initial screening of community DNA and bacterial isolates. Four distinct field sites with differing land- use will be sampled, one site has a strong selection pressure via use of streptomycin as a crop bacteriocide. HGTs will be established using phylogenetic incongruency, GC content, and codon usage analysis. Within actinomycete populations the role of HGT in the evolution of antibiotic production will be investigated.
