Scientists studied how two proteins (BcCbp20 and BcCbp80) work together in gray mold fungus, which destroys crops worldwide. These proteins control how the fungus grows, makes spores, forms long-term survival structures, and causes disease. The findings show that BcCbp80 is more important for growth and infection, while BcCbp20 helps the fungus survive stress. Understanding these proteins could help develop new antifungal treatments.
