Abstract
The ability to construct defined genetic mutations in many bacteria is difficult and limited. Transposon mutagenesis is often highly efficient, but is not site specific, thus selections are often needed to identify mutants of interest. The construction of arrayed mutant libraries would help to fill this need, though these libraries are costly and time consuming. To enable easier construction of arrayed libraries we developed a workflow and methodology using a hierarchical barcoding scheme to identify mutants within a multiwell plate. We applied this method to the marine Alphaproteobacterium Ruegeria pomeroyi DSS-3 and created a library with over 2,800 disrupted genes.
