A Catalyst article about phytoplasmas which are micro-organisms that affect crop plants modifying their growth. The article looks at the damage that they can inflict on crops which in turn can cause famine. Botanists are seeking to counter the effects of phytoplasma disease and the article looks at laboratory research so far.
