Abstract

is one of the traditional Chinese medicinal mushrooms and is used to reduce inflammation, treat diuretic and upset stomach, and prevent cancer. Here, we present a genomic resource of (ACCC 51706) for further understanding its biology and exploration of the synthesis pathway of bioactive compounds. Genomic DNA was extracted and then subjected to Illumina HiSeq X Ten and PacBio Sequel I sequencing. The final genome is 40.66 Mb in size, with an N scaffold size of 36.6 Mb, and encodes 10 181 putative predicted genes. Among them, 6931 genes were functionally annotated. Phylogenomic analysis suggested that and were not clustered together into a group and the latter was grouped with the Polyporaceae. Further, we also identified 377 carbohydrate-active enzymes (CAZymes) and 15 secondary metabolite biosynthetic gene clusters. This is the first genome-scale assembly and annotation for an species. The identification of novel secondary metabolite biosynthetic gene clusters would promote pharmacological research and development of novel bioactive compounds in the future.

摘要

是一种传统的中药材,具有抗炎、利尿和止吐、预防癌症等功效。在这里,我们提供了 (ACCC 51706)的基因组资源,以进一步了解其生物学特性,并探索生物活性化合物的合成途径。提取基因组 DNA,然后进行 Illumina HiSeq X Ten 和 PacBio Sequel I 测序。最终基因组大小为 40.66 Mb,N 支架大小为 36.6 Mb,编码 10181 个推定的预测基因。其中,6931 个基因具有功能注释。系统发育分析表明, 和 没有聚类在一起,后者与多孔菌科聚在一起。此外,我们还鉴定了 377 个碳水化合物活性酶 (CAZymes) 和 15 个次生代谢物生物合成基因簇。这是首个 种的全基因组组装和注释。鉴定新的次生代谢物生物合成基因簇将有助于未来的药理学研究和新型生物活性化合物的开发。
