Suppression of Alternaria brassicicola infection by volatile compounds from spent mushroom substrates.

Most commercially circulating mushrooms are produced via cultivation using artificially produced mushroom substrates. However, after mushroom harvesting, the disposal of spent mushroom substrates (SMSs) is a serious problem for the mushroom industry owing to the need for a disposal site and the cost involved. Thus, in view of the possibility of recycling SMSs as a soil modifier, we examined the effect of soil mixed with SMSs on the infection of Arabidopsis leaves by Alternaria brassicicola, the causal agent of cabbage leaf spot.

Morphological, cytological and genetic analyzes of the 'sango' mutant with the defects in basidiocarp development in edible mushroom Pleurotus pulmonarius.

A spontaneous, morphological variation 'sango' was observed in the progeny of a Pleurotus pulmonarius (Fr.) Quél. wild-type basidiocarp (also known as fruiting body) collected from the field.

Isolation of 6-hydroxy-L-tryptophan from the fruiting body of for use as a tyrosinase inhibitor.

Tyrosinase is the key enzyme that controls melanin formation. We found that a hot water extract of the lyophilized fruiting body of the fungus inhibited tyrosinase from . The extract was fractionated by ODS column chromatography, and an active compound was obtained by purification through successive preparative HPLC using an ODS and a HILIC column.

An MSH4 homolog, stpp1, from Pleurotus pulmonarius is a "silver bullet" for resolving problems caused by spores in cultivated mushrooms.

The enormous number of spores produced by fruiting bodies during cultivation of mushrooms can lead to allergic reactions of workers, reduction of commercial value, spread of mushroom disease, pollution of facilities, and depletion of genetic diversity in natural populations. A cultivar harboring a sporulation-deficient (sporeless) mutation would be very useful for preventing these problems, but sporeless commercial cultivars are very limited in usefulness because sporeless traits are often linked with traits that are unfavorable for commercial cultivation. Thus, identifying a causal gene of a sporeless phenotype not linked to the adverse traits in breeding and cultivation is crucial for the establishment of sporeless breeding using a strategy employing targeting induced local lesions in genomes (TILLING) in cultivated mushrooms.

Construction of a genetic linkage map based on amplified fragment length polymorphism markers and development of sequence-tagged site markers for marker-assisted selection of the sporeless trait in the oyster mushroom (Pleurotus eryngii).

A large number of spores from fruiting bodies can lead to allergic reactions and other problems during the cultivation of edible mushrooms, including Pleurotus eryngii (DC.) Quél. A cultivar harboring a sporulation-deficient (sporeless) mutation would be useful for preventing these problems, but traditional breeding requires extensive time and labor.

A genetic linkage map of Pleurotus pulmonarius based on AFLP markers, and localization of the gene region for the sporeless mutation.

In the cultivation of edible mushrooms, including Pleurotus pulmonarius (Fr.) Quel., the enormous number of spores produced by fruiting bodies can adversely affect mushroom growers' health, mushroom cultivation facilities, and the genetic diversity of natural populations.
