, also known as "Sanghuang" in China, is a well-known genus of traditional Chinese medicinal macrofungi. To make more effective use of resources, we completed the first genome assembly and annotation of a monokaryon strain of in the present study. A 33.96-Mb genome sequence was assembled as 13 contigs, leading to prediction of 9377 protein-coding genes. Phylogenetic and average nucleotide identity analyses indicated that the genome is closely related to those of other species in evolutionary tree, which clustered in one clade. Collinearity analysis revealed a high level of collinearity of with , , and . Biosynthesis pathways potentially involved in medicinal properties, including terpenoid and polysaccharide synthesis, were identified in , while polysaccharides were identified as the main medicinal metabolites in , with flavonoids more important in than other medicinal mushroom groups. Genes encoding 332 carbohydrate-active enzymes were identified in the genome, including major glycoside hydrolases and glycosyltransferases predicted, revealing the robust lignocellulose degradation capacity of . Further, 130 genes, clustered in seven classes were annotated to encode cytochromes P450 in the genome. Overall, our results reveal the remarkably medicinal capacity of and provide new insights that will inform the study of evolution and medicinal application of . The data are a reference resource for the formulation of scientific and rational ecological protection policies for species.
密纹褶孔菌,又称“桑黄”,是中国传统药用大型真菌的一个知名属。为了更有效地利用资源,我们在本研究中完成了单核菌株的第一个基因组组装和注释。组装得到了 33.96-Mb 的基因组序列,由 13 个连续序列组成,预测了 9377 个蛋白编码基因。系统发育和平均核苷酸同一性分析表明,该 基因组与进化树中其他 种的基因组密切相关,它们聚类在一个分支中。共线性分析显示, 与 、 和 之间具有高度的共线性。在 中鉴定出了与药用特性相关的生物合成途径,包括萜类和多糖合成,而在 中鉴定出了多糖是主要的药用代谢物,黄酮类在 中的重要性高于其他药用蘑菇群。在 基因组中鉴定出了 332 个碳水化合物活性酶基因,包括预测的主要糖苷水解酶和糖基转移酶,揭示了 具有强大的木质纤维素降解能力。此外,在 基因组中注释了 130 个基因,聚类在七个类中,编码细胞色素 P450。总的来说,我们的结果揭示了 显著的药用能力,并提供了新的见解,将为 进化和药用应用的研究提供信息。该数据为制定密纹褶孔菌物种的科学合理的生态保护政策提供了参考资源。
