Vibrio fischeri D-glutamate suppressor generation and characterization
This study used D-glutamate auxotrophic mutants of Vibrio fischeri to study the evolution of peptidoglycan biosynthesis and structure. Suppressor mutants were generated by growing an auxotrophic strain without necessary exogenous D-glutamate. Mutants were then characterized and genome sequenced, in order to determine the mechanism of suppression.
