Scientists discovered a special deep-sea fungus from the Mariana Trench (nearly 7 miles deep) and studied how it survives extreme pressure and harsh conditions. By examining its DNA and turning off a specific gene called hog1, they found this gene is crucial for the fungus to handle stress and produce energy. Understanding how this deep-sea fungus adapts could help us develop stronger microorganisms for various applications and better understand how life survives in Earth’s most extreme environments.
