title: Fusarium circinatum isolates from northern Spain are commonly infected by three distinct mitoviruses.
abstract: Pitch canker is a serious disease of pines caused by the ascomycete fungus Gibberella circinata (anamorph = Fusarium circinatum). Three distinct mitovirus strains have been described in this fungus: Fusarium circinatum mitovirus 1 (FcMV1), FcMV2-1 and FcMV2-2. Here, we investigated the frequency and population variation of these viruses and closely related sequence variants in northern Spain using RT-PCR and sequencing. Each virus strain and similar sequence variants shared >95 % sequence identity and were collectively designated as virus types. All virus types were relatively common in Spain, with estimated prevalence of 18.5 %, 8.9 % and 16.3 % for FcMV1, FcMV2-1 and FcMV2-2, respectively.
