Abstract
Type VI secretion systems are molecular syringes used by Gram-negative bacteria to kill heterospecific (non-kin) niche competitors. In this issue of Cell, Mashruwala et al. show that colonies of the pathogen Vibrio cholera can also exhibit T6SS-mediated cell killing of kin cells and that this process benefits emerging resistant mutants, thereby increasing genetic diversity.
