Scientists develop fungus-immune banana

In a small plantation in the Northern Territory, Australia, a group of Cavendish banana plants have defied the odds. For over seven years, these plants have been growing healthily in soil contaminated with the Fusarium oxysporum fungus, the cause of the dreaded Panama TR4 disease, which has devastated banana crops in various countries. According to the Australian Broadcasting Corporation (25/10/2025), the difference lies in their DNA: these are the QCAV-4, the world's first genetically modified banana approved for commercial cultivation. Developed by scientists from the Queensland University of Technology (QUT), the variety received a resistance gene from the wild banana Musa acuminata ssp. malaccensis. This gene allows the plant cells to quickly detect the fungus and activate defense mechanisms similar to the immune system of mammals, preventing the spread of infection. The result is a plant capable of surviving for years in soils where conventional banana plants die within a few ...
