This research examined how a virus affects the fungus that causes disease in plants like cotton and rice. The study found that when the fungus is infected with the virus, it becomes less harmful to plants and can’t survive at higher temperatures. This has important implications for agriculture and plant disease control. Impacts on everyday life: • Could lead to new biological methods for controlling plant diseases • May help protect cotton crops from fungal damage • Demonstrates how viruses can be used beneficially in agriculture • Contributes to understanding natural disease control mechanisms • Could reduce the need for chemical fungicides in farming
