Project description:Ophiocordyceps sinensis (Berk.) Sacc., a complex of larval carcass (sclerotium) and stroma formed by the fungus of Hirsutella sinensis infecting Hepialidae insect larvae, whose fruiting body is also the main fungal structure used for taxonomic identification. However, the induction of fruiting body is still inefficient and the high cost resulting in the large-scale artificial cultivation of this fungus has been unsuccessful in China.In this study,important factors and target genes associated with the fruiting body induction during the development of O. sinensis were identified, providing a basic molecular mechanism for facilitating the large-scale artificial cultivation of O. sinensis.
Project description:Chinese cordyceps is of particular interest for its confined distribution, mysterious lifecycle, ecological importance and developmental biology. The large scale artificial cultivation of this fungus has been succeeded in China until recently but with low efficiency and high cost being ascribed to too much unsolved biological issues, such as gene expression during development and the sexuality reproduction. The success of artificial cultivation provides the convenient for sampling during the different development stages.

Project description:Sequencing of soil microbial communities in the cultivation of morel mushrooms
Project description:Mining of fungal genomes uncovered their great potential for the production of novel secondary metabolites (SMs). However most of them stay silent under standard laboratory cultivation conditions. Co-cultivation of fungi with organism that occur in their natural habitat has shown to be trigger for the activation of such silent SM gene clusters. Recently, we showed that the cultivation of Aspergillus nidulans with the bacterium Streptomyces rapamycinicus leads to the activation of the orsellinic acid gene cluster. Hence we decided to study this interaction further to gain insight into the regulation of SM gene clusters and more specifically to study the chromatin remodelling network actuve upon co-cultivation of the two organisms. This study gives novel insight into the regulation of the orsellinic acid gene cluster and the interaction of the two organisms. To the best of our knowledge this is the first report of mapping the chromatin landscape of microbial interactions, making this study a role model for the analysis of similar systems.
