Modern metagenomic approaches enable the effective discovery of novel viruses in previously unexplored organisms. Termites are significant ecosystem converters and influencers. As with the majority of tropical forest insects, termites are studied insufficiently, and termite virome remains especially understudied. Here, we studied the virome of lichenophagous and mycophagous termites (, and ) collected in the Cat Tien National Park (Vietnam). We assembled four full genomes of novel viruses related to , , and . We also found several contigs with relation to and that did not correspond to complete virus genomes. All the novel viruses clustered phylogenetically with previously identified viruses of the termites. Deltaflexi-like contigs were identified in the fungi-cultivating and showed homology with viruses recently discovered in the edible basidiomycete mushrooms.
现代宏基因组学方法可有效发现先前未被探索的生物体中的新型病毒。白蚁是重要的生态转化者和影响者。与大多数热带森林昆虫一样,白蚁的研究还很不充分,白蚁病毒组的研究尤其不足。在这里,我们研究了在越南的卡蒂恩国家公园(Cat Tien National Park)采集的食菌和食木白蚁(、和)的病毒组。我们组装了四个与、、和相关的新型病毒的完整基因组。我们还发现了一些与和不对应完整病毒基因组的与 contigs。所有新型病毒都与先前鉴定的白蚁病毒在系统发育上聚类。在真菌栽培的中鉴定出了类德尔塔 flexi 病毒 contigs,与最近在可食用的担子菌蘑菇中发现的病毒具有同源性。
