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:The RNA-Seq technique was used to investigate the differentially transcribed genes of the caterpillar fungus Cordyces militaris. It was calculated that >63% of total annotated genes were expressed, including >55% of putative pathogen-host interaction genes. Overall, the fruiting-body development and mycelium growth by C. militaris activated high expression levels of genes in association with translation and post-translational modifications. Otherwise, there were many differentially expressed genes when the fungus was grown on insect pupae to different stages or in liquid medium. In general, the transcriptional profiles were more similar with each other during fungal fruiting-body developmental stages than during growth in a liquid culture. Examination of differential gene expressions by Cordyceps militaris during fruiting-body developments on silkmoth pupae and growth in a liquid medium.
