title: DIY series of genetic cassettes useful in construction of versatile vectors specific for Alphaproteobacteria.
abstract: We have developed a DIY (Do It Yourself) series of genetic cassettes, which facilitate construction of novel versatile vectors for Alphaproteobacteria. All the cassettes are based on defined genetic modules derived from three natural plasmids of Paracoccus aminophilus JCM 7686. We have constructed over 50 DIY cassettes, which differ in structure and specific features. All of them are functional in eight strains representing three orders of Alphaproteobacteria: Rhodobacterales, Rhizobiales and Caulobacterales. Besides various replication and stabilization systems, many of the cassettes also contain selective markers appropriate for Alphaproteobacteria (40 cassettes) and genetic modules responsible for mobilization for conjugal transfer (24 cassettes). All the DIY cassettes are bordered by different types of polylinkers, which facilitate vector construction. Using these DIY cassettes, we have created a set of compatible Escherichia coli-Alphaproteobacteria mobilizable shuttle vectors (high or low copy number in E. coli), which will greatly assist the genetic manipulation of Alphaproteobacteria.
