This research investigated how a virus affects the growth and production of oyster mushrooms, a widely cultivated edible mushroom. The study found that infected mushrooms grow more slowly, develop abnormally, and produce significantly fewer mushrooms compared to healthy ones. This virus can also spread between different mushroom cultures through direct contact. Impacts on everyday life: • Reduced availability and potentially higher prices of oyster mushrooms due to viral infection • Lower quality mushrooms with abnormal appearance in markets • Economic losses for mushroom farmers and producers • Need for better disease management in mushroom cultivation • Importance of maintaining virus-free mushroom cultures for sustainable production
