A novel bisegmented double-stranded RNA virus was identified in the mycoparasitic and opportunistic fungus Hypomyces chrysospermus. The RNA1 genome segment comprises 1866 bp and encodes an RNA-dependent RNA polymerase (RdRp). The RNA2 segment comprises 1822 bp and encodes a capsid protein. Phylogenetic analysis of the RdRp protein indicated that this virus is a new member of genus Alphapartitivirus in the family Partitiviridae. We have designated this mycovirus as "Hypomyces chrysospermus partitivirus 1" (HcPV1). HcPV1 is highly transmissible with aleurioconidia and is present in large amounts within growing mycelium in comparison to the GAPDH reference gene.
一种新型的分段双链 RNA 病毒在寄生性和机会性真菌 Hypomyces chrysospermus 中被鉴定出来。RNA1 基因组片段包含 1866 个碱基对，编码 RNA 依赖性 RNA 聚合酶（RdRp）。RNA2 片段包含 1822 个碱基对，编码衣壳蛋白。RdRp 蛋白的系统发育分析表明，该病毒是呼肠孤病毒科（Partitiviridae）中的一个新的 Alphapartitivirus 属成员。我们将这种真菌病毒命名为“Hypomyces chrysospermus partitivirus 1”（HcPV1）。与 GAPDH 参考基因相比，HcPV1 可以通过粉孢子高度传播，并且在生长的菌丝中大量存在。
