【 摘 要 】

Paecilomyces hepialid (PH) is an endoparasitic fungus of Cordyceps sinensis (CS) and has become a substitute for CS due to their similar pharmacological activities. Because the market demand for CS is difficult to satisfy, and cordycepin, the effective compound of CS, is difficult to industrially produce, we produced 5 samples of PH by culturing for different durations and adding different additives to the culture broth, and detected their cordycepin content with UPLC ESI MS/MS. Then we grouped these cultures into five transcriptome comparisons containing 3 time variable groups and 2 additive variable groups. We used next-generation (NG) sequencing methods to acquire transcriptomic information and investigated the response of gene expression to the additives and the influence of different growth stages. This work will contribute to a better understanding of purine metabolism in PH, and possibly in other Cordyceps species. It will provide a useful resource to further advance transcriptomics studies in Cordyceps species.
