[Reactive oxygen species and the strategy of the antioxidant defense in fungi: a review].

The level of reactive oxygen species (ROS) in the cell regulates the growth and differentiation of the fungal organism. This review considers the pathways of generation of the primary ROS and the defense methods used by fungi and yeasts against them as well as the involvement of thiol compounds in the antioxidant defense of the fungal cell. It is demonstrated that the adaptation of fungi to oxidative stress is tightly connected with the redox-dependent changes in the activities of antioxidant defense components.
