Schizophyllum commune is a sap-rot basidiomycete and cosmopolitan species. The fungus is also recognized as a plant pathogen that causes wood rot on living trees, and many plant species including fruit and ornamental trees have been recorded as hosts. In this paper, previous studies on the plant parasitism of S. commune and related information to date were reviewed, in addition to the unique characters of the fungus. Though the fungus is only a poor wood decomposer in vitro, it preferably invades living tissues of plants including bark and sapwood, being exceptional as a wood-rot basidiomycete. Basidiospores are abundantly ejected in the air, and pruning wounds, freeze injuries and sunscald lesions are major infection courts for them. Wood-rot disease by the fungus is promoted by drought, freezing temperatures and other weather conditions unfavorable for plants; the fungus is adapted to such adverse environmental conditions. It is expected that, depending on plant species and localities, ongoing global warming enhances plant damage, which may predispose plants to fungal infection. Schizophyllum rot possibly helps other wood-rot pathogens to infect and establish. More attention should be paid to the wood-rot disease complex in which S. commune is involved. In conclusion, various aspects on the biology of S. commune still remain to be studied in relation to the mechanism of its pathogenesis.Discipline: Plant disease Additional key words: broad host range, latent infection, sap rot, white rot, wood-rot disease Present address:

“…S. commune is often considered a saprot basidiomycete (Schmidt, 2006;Takemoto, Nakamura, Imamura, & Shimane, 2010) but is also described as a saprobe (Nicolotti, Martinis, & Tamietti, 1998;Padhiar, Albert, Nagadesi, & Arya, 2010), associated with sapwood rot or heart rot in more than 70 species of landscape trees including acacia, eucalypt, ash and tamarind (Hickman, Perry, & Davis, 2011). This fungus is also recognized as a cause of heart rot (Oprea, Sesan, & Balan, 1994;Visarathononth, 1990 The number of Ascomycete OTUs identified from direct DNA extracts was 1.6-fold higher than that of Basidiomycete fungus taxa, almost half of which were yeasts and not regarded as significant in wood decay processes. This ratio reinforces the results from isolation by which Ascomycete species were threefold greater than Basidiomycete species.…”

Acacia hybrid (Acacia mangium × Acacia auriculiformis) clones are widely planted in Vietnam with a total of approximately 400,000 ha to meet the demand for pulpwood, sawn timber and wood chip exports. Silvicultural techniques such as pruning and thinning have been applied to improve productivity and sawlog quality of Acacia hybrid plantations. However, those techniques may also create opportunities for wood decay fungi to enter the Acacia hybrid stems through wounds and cause stem defects that reduce sawlog quality and the value of the plantation. The presence of fungal decay agents in Acacia hybrid trees was examined in two Vietnamese plantations. In July 2011, just prior to a second thinning, discoloured wood samples were taken from a three-year-old Acacia hybrid plantation at Phan Truong Hai for the isolation of fungi. In July 2012, approximately 18 months after pruning and thinning treatments, discoloured wood samples were taken from a three-year-old Acacia hybrid plantation at Nghia Trung for the isolation of fungi. DNA sequencing of the rDNA ITS identified the isolates. In May 2015, approximately 4 years after thinning and fertilizer treatments, discoloured and decayed wood samples were taken from the above (7-year-old) Acacia hybrid plantation at Phan Truong Hai for fungal identification.DNA was extracted directly from discoloured and decayed wood samples and fungal rDNA ITS amplicons sequenced on a Roche 454 sequencer. The results showed that silvicultural treatments did not affect the fungal communities associated with discoloured and decayed wood of Acacia hybrid plantation at Phan Truong Hai. A total of 135 fungal species or OTUs (operational taxonomic units) were identified, including 82 members of Ascomycota and 52 Basidiomycota.
