For a long time, it was thought that the sole role of the immune system was to distinguish between friend and foe and to fend off pathogens. In fact, it is more like a microbial management system that is also involved in accommodating beneficial microorganisms in the plant when required. Researchers from the Max Planck Institute for Plant Breeding Research in Cologne in collaboration with an international consortium of other laboratories discovered this relationship between the model plant Arabidopsis thaliana, or thale cress, and the fungus Colletotrichum tofieldiae. The plant tolerates the fungus when it needs help in obtaining soluble phosphate from the soil and rejects the microbe if it can accomplish this task on its own.
