Table 1. Typical characteristics of selected model basidiomycetes representative of preferring different plant material/components degradation.
Name of the basidiomycete | Type of fungi | Well-known for | Substrate preference | Preference of degradation of plant component | P450 count | References |
Phanerochaete chrysosporium | White rot | Model fungus for understanding the mechanism of wood degradation | Hardwood | Efficiently degrades all plant cell wall components (lignin, cellulose and hemicellulose) | 149 | 4, 19, 41 |
Phanerochaete carnosa HHB-10118-Sp. | White rot | Model fungus for understanding the mechanism of softwood degradation | Softwood (coniferous wood) | Efficiently degrades all plant cell wall components (lignin, cellulose and hemicellulose) | 266 | 10 |
Agaricus bisporus var bisporus (H97) | – | Model fungus for understanding the adaptation, persistence, and growth in the humic-rich leaf litter environment. Premier cultivated button mushroom. | Leaf and litter | Non-wood secondary decomposer, leaf and needle litter degrader | 109 | 21, 44 |
Ganoderma sp. 10597 SS1 v1.0/Ganoderma lucidum strain 260125-1 | White rot | Shelf mushrooms or bracket fungi/model fungus for study of the biosynthesis of natural medicines | Softwood and hardwood | Capable of removing plant cell wall components, either lignin only (selective delignification) or both lignin and cellulose | 209/198 | 9, 11,12 |
Postia placenta MAD 698-R | Brown rot | Model brown rot fungus used for study of wood degradation | Hardwood | Primarily degrades plant cell wall component cellulose and hemicellulose | 190 | 5, 20 |
Serpula lacrymans S7.3 | Brown rot (dry rot) | Model system to study evolutionary processes and life history traits in basidiomycetes. Well known as dry rot, destroyer of indoor wood construction, | Dry hardwood | Primarily degrades plant cell wall component cellulose and hemicellulose | 164 | 6, 44 |
Out-group fungi (non-wood-degraders) | ||||||
Tremella mesenterica | Golden jelly fungus | Mycoparasite | – | – | 8 | 8,44 |
Cryptococcus neoformans | Opportunistic pathogen | Animal pathogen/parasite | – | – | 10 | 46,52 |
As an out-group, the non-wood-degrading basidiomycete species, Tremella mesenterica (mycoparasite) and Cryptococcus neoformans (animal pathogen/parasite) are also shown in the table. Phanerochaete carnosa has been exclusively isolated from softwood (10) has been represented as model basidiomycete for understanding the mechanism of softwood degradation. In comparison to Ganoderma lucidum, the model medicinal mushroom (9), Ganoderma sp. proved to have an additional 10 sub-families in its genome (12). For this reason, in this study we used Ganoderma sp. P450s as representative of Ganoderma lucidum.
