Spore formation by the bacterium Bacillus subtilis is an elaboratedevelopmental process that is triggered by nutrient limitation.Here we report that cells that have entered the pathway to sporulateproduce and export a killing factor and a signaling proteinthat act cooperatively to block sister cells from sporulatingand to cause them to lyse. The sporulating cells feed on thenutrients thereby released, which allows them to keep growingrather than to complete morphogenesis. We propose that sporulationis a stress-response pathway of last resort and that B. subtilisdelays a commitment to spore formation by cannibalizing itssiblings.
