Unveiling the Genetic Switch: Transforming Harmful Fungi into Allies

Researchers have discovered that a specific gene cluster in the fungus Colletotrichum tofieldiae determines whether it supports or inhibits plant growth, challenging traditional distinctions between harmful pathogens and beneficial microbes. Activation of this gene cluster determines the negative impact of the fungus on the host plant, and when disrupted, the fungus changes its behavior from inhibiting growth to promoting it. Understanding these mechanisms could enhance global food security and reduce food waste by harnessing the beneficial role fungi can have on food.
