Basidiomycota Fungi and ROS: Genomic Perspective on Key Enzymes Involved in Generation and Mitigation of Reactive Oxygen Species

Our review includes a genomic survey of multitude reactive oxygen species (ROS) related intra- and extracellular enzymes proteins among fungi Basidiomycota, following their taxonomic classification within the systematic classes orders, focusing on different fungal lifestyles (saprobic, symbiotic, pathogenic). Intra- ROS metabolism-involved (49 protein families, summing 4170 models) were searched as encoding genes 63 genomes selected according to current taxonomy. Extracellular intracellular metabolism mechanisms in Basidiomycota are illustrated detail. In brief, it may be concluded that differences between set activated by ROS, especially H 2 O , involved generation follow lifestyles. The wood plant biomass degrading white-rot litter-decomposing Agaricomycetes contain highest counts for various peroxidases, mono- peroxygenases, oxidases. These findings further confirm necessity multigene families oxidoreductases efficient complete degradation lignocelluloses fungi. High variations sizes ROS-involved gene found, however, with mycorrhizal symbiotic lifestyle. addition, there some sets thiol-mediation involving proteins, existence enzyme quenching ROS. animal- plant-pathogenic species, absent or rare. these fungi, peroxidases seemingly minor role than independent saprobic, filamentous Basidiomycota. Noteworthy is our literature point both well response oxidative stress mitigation Ascomycota.
