is an edible fungus which was approved as a novel food by the Chinese Ministry of Public Health in 2013. It also has a broad prospect of application in pharmaceutical industries, with many medicinal activities. In this study, the whole genome of GD15, a single spore isolate from a wild strain, was sequenced and assembled with Illumina and PacBio sequencing technology. The generated genome is 29.05 Mb in size, comprising nine scaffolds with an average GC content of 57.01%. It is predicted to contain a total of 9150 protein-coding genes. Sequence identification and comparative analysis indicated that the assembled scaffolds contained two complete chromosomes and four single-end chromosomes, showing a high level assembly. Gene annotation revealed a diversity of transposons that could contribute to the genome size and evolution. Besides, approximately 15.57% and 12.01% genes involved in metabolic processes were annotated by KEGG and COG respectively. Genes belonging to CAZymes accounted for 3.15% of the total genes. In addition, 435 transcription factors, involved in various biological processes, were identified. Among the identified transcription factors, the fungal transcription regulatory proteins (18.39%) and fungal-specific transcription factors (19.77%) represented the two largest classes of transcription factors. This genomic resource provided a new insight into better understanding the relevance of phenotypic characters and genetic mechanisms in .
是一种可食用真菌，于2013年被中国卫生部批准为新食品。它在制药行业也有广阔的应用前景，具有多种药用活性。在本研究中，对一株野生菌株的单孢分离株GD15的全基因组进行了测序，并采用Illumina和PacBio测序技术进行组装。生成的基因组大小为29.05 Mb，由9个支架组成，平均GC含量为57.01%。预计总共包含9150个蛋白质编码基因。序列鉴定和比较分析表明，组装的支架包含两条完整染色体和四条单端染色体，显示出高水平的组装。基因注释揭示了多种转座子，它们可能对基因组大小和进化有贡献。此外，分别有大约15.57%和12.01%参与代谢过程的基因被KEGG和COG注释。属于碳水化合物活性酶的基因占总基因的3.15%。此外，鉴定出435个参与各种生物过程的转录因子。在鉴定出的转录因子中，真菌转录调节蛋白（18.39%）和真菌特异性转录因子（19.77%）是两类最大的转录因子。这一基因组资源为更好地理解[具体物种]的表型特征与遗传机制之间的相关性提供了新的见解。
