Geographical diversity of proteomic responses to cold stress in the fungal genus Pseudogymnoascus

In understanding stress response mechanisms in fungi, cold stress has received less attention than heat stress. However, cold stress has shown its importance in various research fields. The following study examined the cold stress response of six Pseudogymnoascus spp. isolated from various biogeogra...
