Genome assembly of the edible jelly fungus Dacryopinax spathularia (Dacrymycetaceae)

The edible jelly fungus Dacryopinax spathularia (Dacrymycetaceae) is wood-decaying and can be commonly found worldwide. It has found application in food additives, given its ability to synthesize long-chain glycolipids, among other uses. In this study, we present the genome assembly of D. spathularia using a combination of PacBio HiFi reads and Omni-C data. The genome size is 29.2 Mb. It has high sequence contiguity and completeness, with a scaffold N50 of 1.925 Mb and a 92.0% BUSCO score. A total of 11,510 protein-coding genes and 474.7 kb repeats (accounting for 1.62% of the genome) were predicted. The D. spathularia genome assembly generated in this study provides a valuable resource for understanding their ecology, such as their wood-decaying capability, their evolutionary relationships with other fungi, and their unique biology and applications in the food industry.

可食用胶质真菌匙盖假花耳（Dacryopinax spathularia）隶属于花耳科（Dacrymycetaceae），是一种木材腐朽真菌，在全球范围内广泛分布。因其可合成长链糖脂的特性，该物种已被应用于食品添加剂领域，并有其他多种用途。本研究结合PacBio HiFi测序读段与Omni-C技术数据，完成了匙盖假花耳的基因组组装。该基因组大小为29.2 Mb，序列连续性与完整性俱佳，scaffold N50达到1.925 Mb，BUSCO（Benchmarking Universal Single-Copy Orthologs）评估完整性为92.0%。本研究共预测得到11510个蛋白质编码基因，以及474.7 kb的重复序列（占基因组总长的1.62%）。本研究获得的匙盖假花耳基因组组装结果，为解析该物种的生态学特性（如木材腐朽能力）、与其他真菌的进化关系，以及其独特的生物学特性与食品工业应用价值提供了宝贵的研究资源。
