Identification of aggressive species of Trichoderma from button mushroom farms (Agaricus bisporus) using morphological and molecular methods
Authors
Abstract:
Different species of Trichoderma especially T. harzianum (Th2 biotype in Europe and Th4 in America) considered as causal agent of green mould disease on button mushroom (Agaricus bisporus) casing beds. In this study, 100 fungal isolates were collected and purified from different mushroom growing units in Tehran province and Urmia (NW Iran). Totally, 60 isolates of T. harzianum, 27 isolates of T. virens, seven isolates of T. hamatum and six isolates of T. inhamatum were morphologically identified. The main infectious agent was T. harzianum. Specific primers were used for identification of different biotypes.

Whole-genome Sequencing of the Cultivated Button Mushroom Agaricus Bisporus:
The culmination of the first half-century of investigations into the genome of Agaricus bisporus was marked by the first whole-genome sequencing for a strain of this species. The genome of a second strain of A. bisporus was sequenced the following year. While a structural view of the genome is now effectively complete, functional interpretations of the many gene sequences, supported by accumula...

Agaricus bisporus, grown under standard composting conditions, was evaluated for its ability to produce lignin-degrading peroxidases, which have been shown to have an integral role in lignin degradation by wood-rotting fungi. The activity of manganese peroxidase was monitored throughout the production cycle of the fungus, from the time of colonization of the compost through the development of f...

Many recent studies have shown that glycosylation patterns of Agaricus bisporus are similar to those of mammalians, so that this organism is a good candidate for the expression of glycosylated pharmaceutical protein. To achieve constant interested gene expression in all cells of the organism, proper promoter isolation is necessary. To isolate this promoter, PCR with specific primers was perform...

Green mold disease (causal agent, Trichoderma) has resulted in severe crop losses on mushroom farms worldwide in recent years. We analyzed 160 isolates of Trichoderma from mushroom farms for morphological, cultural, and molecular characteristics and classified these isolates into phenotypic groups. The most common group comprised approximately 40% of the isolates and was identified as a strain ...

To promote the selection of promising monokaryotic strains of button mushroom (Agaricus bisporus) during breeding, 61 progeny strains derived from basidiospores of two different lines of dikaryotic parental strains, ASI1038 and ASI1346, were analyzed by nucleotide sequencing of the intergenic spacer I (IGS I) region in their rDNA and by extracellular enzyme assays. Nineteen different sizes of I...
