The mycoparasitic oomycete Pythium nunn isolate UZ415 contains two double-stranded RNAs (dsRNAs) of different sizes. The 1707-nt dsRNA1 and the 1475-nt dsRNA2 potentially encode an RNA-dependent RNA polymerase (RdRp) and a coat protein (CP), respectively, with sequence similarity to the RdRp and CP of gammapartitiviruses (< 57% and < 36%). Phylogenetic analysis of the deduced RdRp amino acid sequences indicated that the virus identified from P. nunn is classifiable as a distinct member of the genus Ganmmapartitivirus in the family Partitiviridae. This virus isolate is hereby named Pythium nunn virus 1 (PnV1).
真菌寄生卵菌纽氏腐霉分离株UZ415含有两条大小不同的双链RNA（dsRNA）。1707个核苷酸的dsRNA1和1475个核苷酸的dsRNA2可能分别编码一种RNA依赖的RNA聚合酶（RdRp）和一种外壳蛋白（CP），其序列与γ-分病毒的RdRp和CP具有相似性（分别小于57%和小于36%）。对推导的RdRp氨基酸序列进行系统发育分析表明，从纽氏腐霉中鉴定出的病毒可归类为分病毒科γ-分病毒属的一个独特成员。该病毒分离株在此命名为纽氏腐霉病毒1（PnV1）。
