摘要： Lentinula edodes, a commercially important mushroom, is cultivated worldwide. Artificially cultivated L. edodes often present with abnormal symptoms in the fruiting body, which affect their commercial value and reduce production efficiency. In this study, we carried out a comparative transcriptome analysis of normal fruiting body pileus (LeNP), normal margin in abnormal fruiting body pileus (LeAPNM), and abnormal margin in abnormal fruiting body pileus (LeAPAM). Metabolic pathways such as those involved in transmembrane transport, ribosome production, tryptophan metabolism, arginine and proline metabolism, and the metabolism of other amino acids were significantly enriched in LeAPAM. F-box, short-chain dehydrogenases/reductases, the major facilitator superfamily, and the FMN_red superfamily are related to malformation in L. edodes. Genes encoding heat shock proteins, G protein, and beta-1,3-glucanase in the GH5 family showed different expression patterns, suggesting that these genes are involved in the development of L. edodes fruiting bodies. In particular, CAZymes, which are involved in the development of cell walls in L. edodes, were highly expressed in LeAPAM. According to TEM observation, the cell wall of LeAPAM samples showed significant thickening compared to the other samples. These results suggested that cell wall anabolism in LeAPAM samples was more active than that in normal fruiting bodies, enhancing the environmental adaptability of the fungus. This study provides preliminary data for future research aimed at solving the phenomenon of abnormal fruiting bodies of L. edodes.
