The nucleotide sequences of genome segments 1 and 3 of Rosellinia anti-rot virus (RArV) from a hypovirulent isolate, W370, of the plant pathogen Rosellinia necatrix were determined. The complete nucleotide sequence of the genome segment 1 encoded a putative RNA-dependent RNA polymerase (RDRP). The deduced amino acid sequence of RDRP of RArV showed 29% identity with RDRPs of Colorado tick fever virus (CTFV) and European Eyach virus (EYAV) in the genus Coltivirus, and identities of 23-21% with members of the genera Fijivirus and Cypovirus. Both RArV and the Coltivirus member might have originated from a common virus ancestor.
测定了植物病原菌恶疫霉低毒力分离株W370的玫瑰腐病菌抗病毒（RArV）基因组片段1和3的核苷酸序列。基因组片段1的完整核苷酸序列编码一种假定的RNA依赖性RNA聚合酶（RDRP）。RArV的RDRP推导氨基酸序列与科罗拉多蜱传热病毒（CTFV）和科蒂病毒属的欧洲埃亚奇病毒（EYAV）的RDRP有29%的同一性，与斐济病毒属和呼肠孤病毒属成员的同一性为23%-21%。RArV和科蒂病毒属成员可能起源于共同的病毒祖先。
