Fungal pathogens weaponize ancient host antimicrobial proteins to subvert ecosystems, revealing evolutionary arms race and systemic infection strategies

The evolutionary arms race between plants and fungal pathogens dates back to the Devonian period, with ancient antimicrobial proteins serving as both weapons and shields in this dynamic. Historical collapses like the Irish Potato Famine (1845–1852) and the chestnut blight (early 20th century) exemplify how monocultures amplify the impact of such co-evolutionary adaptations. Colonial agricultural policies, which prioritized cash crops over biodiversity, have repeatedly intensified these vulnerabilities.
The discovery of fungal pathogens repurposing ancient antimicrobial proteins underscores an evolutionary arms race shaped by human interventions, from colonial monocultures to industrial agriculture.
Indigenous and peasant farming systems, which have co-evolved with these pathogens, offer time-tested solutions rooted in biodiversity and soil stewardship, yet remain sidelined in scientific and policy discourse. The scientific focus on infection control obscures the broader ecological roles of these proteins, while climate change intensifies the threat, creating a perfect storm for global food insecurity. Trickster-like fungi expose the absurdity of industrial agriculture’s attempts to dominate nature, revealing the need for humility and collaboration with marginalized knowledge systems. A systemic response must integrate agroecology, indigenous knowledge, and climate-resilient breeding, with governance structures that center the voices of those most affected by fungal outbreaks.
