Abstract

Two double stranded (ds) RNA molecule patterns, probably of viral origin, were sequenced from Gremmeniella abietina var. abietina type A. The genome of Gremmeniella abietina RNA virus L1 (GaRV-L1) from isolate HR2 was 5133 bp and contained two open reading frames (ORFs). The 5′-proximal ORF coded for a putative coat protein (CP) and the 3′-proximal ORF encoded putative RNA-dependent RNA polymerase (RdRp). GaRV-L1 had sequence similarities with a previously described totivirus ( Helminthosporium victoriae 190S virus ) and two unclassified members of family Totiviridae ( Sphaeropsis sapinea RNA virus 1 and Sphaeropsis sapinea RNA virus 2). The genome of Gremmeniella abietina RNA virus MS1 (GaRV-MS1) from isolate C5 was composed of three dsRNA molecules coding for a putative RdRp (dsRNA1), a putative CP (dsRNA2) and protein of unknown function (dsRNA3). The lengths of these dsRNA molecules were 1782, 1586 and 1181 bp, respectively. Sequence comparisons indicated that the GaRV-MS1 dsRNA pattern comprises a putative virus that is highly similar to Discula destructiva virus 1, Discula destructiva virus 2 and Fusarium solani virus 1 of the family Partitiviridae .
