Changes of trehalose content and trehalose-degrading activity during fruit-body formation and autolysis in Pleurotus sp.
Publication date: Available online 13 June 2018Source: MycoscienceAuthor(s): Alireza Arastoo, Masami Nakazawa, Tatsuji Sakamoto, Hitoshi Kobayashi, Kenji Ouchi, Satoshi Inatomi, Mitsuhiro UedaAbstractWe studied how the content and degrading activity of trehalose changed during fruit-body development and autolysis. During the process of autolysis, the trehalose content of whole fruit-bodies decreased sharply whereas the trehalose-degrading activity increased toward the inner region from the outer region of the pilei. Conversely, the trehalose content during autolysis decreased toward the inner region from the outer region o...

Species composition and distribution of Coleosporium species on the needles of Pinus densiflora at a semi-natural vegetation succession site in central Japan
Publication date: Available online 18 June 2018Source: MycoscienceAuthor(s): Hiroyuki Suzuki, Dai Hirose, Yuichi YamaokaAbstractColeosporium species cause pine needle rust. Most species have heteromacrocyclic life cycles, and 12 species use Pinus densiflora as aecial hosts. To understand the biology of rust fungi and develop better methods for controlling rust diseases, it is necessary to clarify that which Coleosporium species affect pine trees. However, Coleosporium on pine trees have rarely been identified at the species level because of their morphological similarities. We used polymerase chain reaction - restriction f...

Spatial diversity of clavarioid mycota (Basidiomycota) at the forest-tundra ecotone
Publication date: July 2018Source: Mycoscience, Volume 59, Issue 4Author(s): Anton G. ShiryaevAbstractThe article studies the change of clavarioid mycota species richness along the longitudinal gradient of climatic continentality in the forest tundra ecotone of Eurasia and the results are discussed for continental and regional levels using the basic climatic variables. It was found that species richness declines, both continentally and regionally, with climate continentality increasing. The Fennoscandian sector situated in the mild maritime climate is the richest, whereas Yakutia, with an ultracontinental harsh climate is ...
