Extremotolerant fungi as genetic resources for biotechnology

摘要

Increased stress tolerance of economically important plants and microorganisms can improve yields in agriculture and industrial microbiology. The pool of resources used for the genetic modification of crops and industrial fungal strains in the past has been relatively limited, and has frequently included only stress-sensitive organisms. However, certain groups of fungi have evolved specialized mechanisms that enable them to thrive under even the most extreme of environmental conditions. These species can be considered as promising sources of biotechnologically interesting genes. Together with a powerful and convenient high-throughput functional screening method, extremotolerant fungi represent a new opportunity for the identification of stress-tolerance-conferring genes. The approaches described here should provide important contributions to the enhancing of the properties of economically important organisms in the future.
