Description
Janina Österman-Udd and co-authors subject a wood-decay fungus to oxidative stress in a 2026 study. White rot fungi digest deadwood and must endure swings in oxygen and chemistry. Peroxide shock mimics one harsh stress they meet in that habitat.
Gene activity was read eighteen hours after the shock, under normal and low oxygen. Over seven hundred genes changed strongly, but the pattern split by atmosphere. Low oxygen cultures mostly switched genes off, many of unknown role. Normal air cultures switched more genes on, led by small secreted proteins and redox enzymes. Sugar pathways, including pentose use and alcohol making, shut down under both. Prior metabolic state likely explains the split.
