A simplified and efficient method for single-step, targeted gene deletion in mycobacteria.

ABSTRACT

Targeted gene deletion in mycobacteria remain complicated, requiring expertise and multiple steps. Here we present a single-step, easy to understand and perform method for targeted gene deletion. Using this method, we successfully deleted several genes in both M. smegmatis and M. abscessus. We believe this method will facilitate molecular research of mycobacteria and make it accessible to a greater number of researchers throughout the world.
