One tiny protein from a tick can actually "brainwash" a deadly crop fungus into being completely harmless.

The Takeaway
Researchers found a peptide in tick immune systems that can rewrite nearly 50% of a fungus's genetic instructions. This massive 'genomic disruption' stops the fungus from growing and prevents it from releasing the toxins that ruin wheat harvests.
From the abstract
Fusarium graminearum is a fungal pathogen causing Fusarium Head Blight (FHB) in wheat and is the main cause of grain contamination with the deoxynivalenol (DON) mycotoxin which is a major threat to food safety and security. The several drawbacks of synthetic fungicides have prompted the search for innovative and eco-friendly solutions. Recently, TickCore3 (TC3), a peptide derived from the defensin DefMT3 of the tick Ixodes ricinus, was shown to efficiently reduce F. graminearum fungal growth and
