Gene fusion and functional diversification of P450 genes facilitate thermophilic fungal adaptation to temperature change

mycolabadmin

Researchers discovered that a thermophilic fungus uses two special genes to adapt to temperature changes. One of these genes is uniquely fused from two different genes, creating a hybrid protein with multiple functions. These genes help the fungus produce iron-binding molecules that stabilize its structure and support its growth when temperatures drop, allowing the fungus to survive in environments from compost piles to stored grains.

Growth Phase-Dependent Changes in the Carbohydrate Metabolism of Penicillium Strains from Diverse Temperature Classes in Response to Cold Stress

This study examined how different fungal strains from cold and warm environments respond to sudden temperature drops. Researchers tracked enzyme activity related to energy production and found that fungi adapted to cold environments handle stress better than warmth-loving fungi. The type of enzyme activity and how old the fungal cells were both affected the response to cold, providing insights that could help predict how disease-causing fungi behave in cold conditions.
