Three of the twelve double-stranded (ds) RNAs, dsRNAs 1a, 1b and 3b, which are located in the mitochondria of a diseased isolate, Ld, of the Dutch elm disease fungus, Ophiostoma novo-ulmi have been cDNA cloned and sequenced. Examination of the sequences of the RdRp genes predicted from the nucleotide sequences of the three dsRNAs suggest that they constitute the genome of three new mitoviruses.
