Abstract：To investigate the metabolic properties and gene expression regulation of the parental and hybrid versions of Flammulina velutipes,the variety FY5 and the hybrid generation F1 of its cross with the wild type as materials were used for transcriptomics and metabolomics analyses.The results showed that a total of 128 differential metabolites were identified,and those with large differences included organic acids,amino acids,ketones,unsaturated fatty acids and polysaccharides.Eighty-seven of them were significantly up-regulated and 41 were significantly down-regulated in the hybrids.A total of 3 329 significantly differentially expressed genes,2 389 up-regulated differentially expressed genes and 940 down-regulated differentially expressed genes were detected.The joint analysis showed that the significantly differentially expressed genes and differential metabolites mainly existed in eight metabolic pathways,including glutathione metabolism and arginine synthesis.
