Discovery of a new defence mechanism in bacteria (IMAGE)
Caption
Model of the mechanism
A (light green) bacterial cell detects a source of stress and is activated (dark green). It adorns itself with alarmones (depicted as red triangles) and can transmit them via cell-to-cell contact with neighbouring cells (black arrows). When the source of stress arrives, the percentage of activated cells increases and converts unstressed neighbouring cells, triggering the mechanism.
