摘要： Light is a vital environmental factor that promotes the growth and development of edible fungi mycelium. Under white light, the mycelium color of Sanghuangporus vaninii shifts during its growth stages. To investigate the impact of visible light on mycelial morphogenesis, a comparative transcriptomic analysis was conducted. This analysis revealed the molecular processes that underpin mycelial growth and development in S. vaninii when cultured in both darkness and light conditions. From the analysis, 13,643 genes were aligned using Illumina raw reads. Of these, 596 genes exhibited significant expression changes under white light exposure. Specifically, 226 genes were upregulated and 370 downregulated, spanning 55 different metabolic pathways. We further classified differentially expressed genes (DEGs), these genes play roles in photomorphogenesis, signal transduction, carbohydrate metabolism, and melanin production, among other processes. Some are also implicated in cell cycle regulation and the differential expression of respiratory functions. The validation of the differentially expressed transcripts using qRT-PCR showed complete agreement with RNA-Seq data for 9 transcripts. Meanwhile, the light had an inhibitory effect on the bioactive components in S. vaninii. These findings offer valuable insights into the transcriptional shifts and molecular mechanisms driving the color change in S. vaninii under light exposure, providing a basis for further research into mechanisms of light-response regulation.
