Detection of the gene cluster involved in resistance toward bacteriocins in B. amyloliquefaciens strains FZB42 and GA1 (A) and those responsible for subtilosin synthesis, immunity and transport in B. subtilis 168 and B. amyloliquefaciens strains GA1. The grey arrows indicate the gene organisation in strain FZB42 (A) and 168 (B). The black lines represent the different gene fragments amplified by PCR using primer pairs as described in Table
