Description

Mengchun Wu and co-authors uncover a single-letter edit switch in a crop fungus in this 2026 study. The fungus causes head blight in cereals, and a protein called Spo11, which cuts DNA to start sexual shuffling, turned out to have a second job holding back the first division.

A stop signal inside the Spo11 message is corrected to a working code only during sexual reproduction, through RNA editing. Without the protein, division speeds up and spores fail. A version born already corrected keeps spores fine but harms growth and division timing. The edit acts as a dial for protein dose, and family history shows it has been gained and lost over time.
