Antifungal Volatile Organic Compounds from Talaromyces purpureogenus CEF642N: Insights from One Strain Many Compounds (OSMAC) Strategy for Controlling Verticillium dahliae in Cotton

Scientists discovered that a beneficial fungus called Talaromyces purpureogenus can produce powerful antifungal compounds that kill cotton wilt disease. By growing this fungus on different nutrient media, researchers identified two main antifungal compounds: 3-octanol and 2-octenal. These natural compounds completely or nearly completely stopped the growth of the cotton wilt pathogen in laboratory tests, offering a promising green alternative to chemical pesticides for protecting cotton crops.

VdPAT1 encoding a pantothenate transporter protein is required for fungal growth, mycelial penetration and pathogenicity of Verticillium dahliae

Verticillium dahliae is a destructive fungus that causes a wilting disease in cotton crops. Researchers found that a specific protein (VdPAT1) that helps the fungus absorb vitamin B5 is critical for its survival and ability to infect cotton plants. When they disabled this protein, the fungus grew poorly, couldn’t penetrate plant tissues effectively, and became much less virulent, suggesting this protein could be a target for controlling the disease.
