Overview

• Fusarium wilt of banana, caused by the TR4 strain, threatens the global Cavendish banana supply.
• The TR4 strain is genetically distinct from the pathogen that wiped out Gros Michel bananas in the 1950s.
• Researchers identified accessory genes linked to TR4's virulence, specifically involving nitric oxide production.
• Eliminating these genes significantly reduces the pathogen's ability to infect banana plants.
• Experts emphasize the importance of agricultural diversity to prevent future outbreaks.
