Ecological factors we analyzed mainly include temperature, altitude, and soil. Our analysis shows that Hubei, Anhui, Yunnan, Guizhou and Sichuan provinces are regions that have highest similarity with original producing areas of Wolfiporia extensa (Peck) Ginns. This is basically consistent with actual conditions. In addition, we predicted some regions (for example, Gansu) that have not been recorded in literature, which provides scientific and reliable data support for seed introduction and expansion of Wolfiporia extensa (Peck) Ginns. Using the GIS-based program for the distribution prediction of traditional Chinese medicine (TCMGIS-II) to analyze suitability of Wolfiporia extensa (Peck) Ginns producing regions is scientific and accurate, and will provide important reference for seed introduction, cultivation and scientific zoning of Wolfiporia extensa (Peck) Ginns.展开更多

Here, we present the genome and transcriptome of the Chinese strain CGMCC5.78 of W. cocos. High-confidence functional prediction was made for 9277 genes among the 10,908 total predicted gene models in the W. cocos genome. Up to 2838 differentially expressed genes(DEGs)were identified to be related to sclerotial development by comparing the transcriptomes of mycelial and sclerotial tissues. These DEGs are involved in mating processes, differentiation of fruiting body tissues, and metabolic pathways. A number of genes encoding enzymes and regulatory factors related to polysaccharide and triterpenoid production were strikingly regulated. A potential triterpenoid gene cluster including the signature lanosterol synthase(LSS) gene and its modified components were annotated. In addition, five nonribosomal peptide synthase(NRPS)-like gene clusters,eight polyketide synthase(PKS) gene clusters, and 15 terpene gene clusters were discovered in the genome. The differential expression of the velevt family proteins, transcription factors,carbohydrate-active enzymes, and signaling components indicated their essential roles in the regulation of fungal development and secondary metabolism in W. cocos. These genomic and transcriptomic resources will be valuable for further investigations of the molecular mechanisms controlling sclerotial formation and for its improved medicinal applications.展开更多
