Project description:True morels (Morchella spp., Morchellaceae, Ascomycota), a delicious edible mushroom, has rapidly expanded in recent years, especially in China. However, a severe disease of morels, red fruitbody disease, led to very low production of fruiting bodies. The cause reason and the mechanisms under red fruitbody are unclear. Herein, we integrated the transcriptomics and metabolomics data of M. sextelata from red fruitbody group (R) and normal group (N), which was artificial cultivation in Fujian province, China. Transcriptome data revealed the differentially expressed genes (DEGs) between R group and N group were significantly enriched in the pathways of tyrosine metabolism, riboflavin metabolism, and glycerophospholipid metabolism. Similarly, the differential accumulated metabolites (DAMs) were mainly assigned to metabolism categories, including tyrosine metabolism, biosynthesis of plant secondary metabolites, biosynthesis of amino acids, and others. Then, combined analysis of the transcriptome data and metabolome traits revealed that the most enriched pathway was tyrosine metabolism, followed by ABC transporters, alanine, aspartate and glutamate metabolism, and others. In summary, this integration of transcriptomics and metabolomics data of M. sextelata during fruitbody redness implicated several key genes, metabolites, and pathways involved in this disease. We believe that these findings will help us understand the mechanisms under fruitbody redness of M. sextelata and provide new clues for optimizing the methods for its cultivation application.
