Co-opting bacterial immune system to turn off specific genes

A technique that co-opts an immune system already present in bacteria and archaea to turn off specific genes or sets of genes -- creating a powerful tool for future research on genetics and related fields -- has been developed by researchers. "This should not only expedite scientific discovery, but help us better engineer microbial organisms to further biotechnology and medicine," says a senior author of a paper on the work. "For example, this could help us develop bacterial strains that are more efficient at converting plant biomass into liquid fuels."
