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.

A Possible Involvement of Sialidase in the Cell Response of the Antarctic Fungus Penicillium griseofulvum P29 to Oxidative Stress

Scientists studied a cold-loving fungus from Antarctica to understand how it survives in extreme cold. They found that when exposed to freezing temperatures, the fungus produces more of an enzyme called sialidase, along with other protective molecules. This appears to be part of the fungus’s survival strategy against the damaging effects of cold stress, helping it protect its cells from oxidative damage.

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

This study examined how three types of fungus respond to cold temperatures by measuring changes in their metabolic enzymes. Researchers exposed young and old fungal cells to cold stress and found that cold temperatures increased enzyme activity in both energy production pathways. Interestingly, the Antarctic psychrotolerant fungus adapted better to cold than the mesophilic fungi, showing that cold-adapted organisms have superior strategies for surviving freezing conditions.

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.
