Researchers, led by Rebecca Bart and Nigel Taylor, have identified a genetic mutation that confers resistance to cassava mosaic disease (CMD), a significant finding that could improve cassava yield and sustain farmer income in regions heavily affected by the disease. The discovery could also have implications for disease resistance in other crops. The research involved documenting disease prevalence in Uganda and identifying the specific genetic region responsible for CMD resistance. Further studies will focus on understanding the mechanism of resistance and exploring other secrets about cassava.
