Reverse Genetics

Forward and reverse genetics
Forward and reverse genetics

Classic, forward genetics examines the genetic cause of a phenotype (an observable characteristic such as the production of a pigment).

Now with genomes widely available, one can directly interrogate the function of a gene by creating deletion mutants for example and this is called reverse genetics.

We are interested in establishing reverse genetics tools for non-model bacteria to facilitate biosynthetic studies and to investigate the roles that natural products play in the environment (1-4).
