An arms race for the control of cell death then ensues: As the bacteria produce more and more IAPs, the host cell ramps up its production of proteins that induce apoptosis. Eventually, after the ...

When plants are infected by parasitic bacteria called phytoplasmas, their flowers turn into leafy shoots, their petals turn green and they develop a mass of shoots called ‘witches’ brooms’.
