The evaluation of germplasm resource of Cordyceps kyushuensis was carried out with the metabolomics technology, from a standpoint of alternation of generations, to summary the changing rules of metabolite. The proposed integrated technology of were established based on sample extraction and pretreatment methods, research methods of GC-MS and LC-MS/MS, to separate and analysis the wide polar metabolites of the mycelium and fruiting body. The potential key metabolites were identificated to establish the appropriate biomarkers library. RNA-Sequence technology and iTRAQ technology were employed to make a comparative transcriptome and proteomic research of cordyceps in the life history evolution. The possible biosynthesis pathway, regulation mechanism and crucial enzymes of cordycepin was speculated and proved by protein micro-array chip and Western blot, laying a solid foundation for the followed study of synthetic biology.This topic research had a profound theoretical and practical significance on construction of core collection, genetic diversity and stability, gene mapping and function discription.
