S-Fig. 1Profile of 1kb DNA Marker#SM0331 (Fermentas,USA) (lane 1) and the dsRNA extracted from the mycelia (lane2) in 1% agarose gel electrophoresis.

S-Fig. 2The electrophoretic profile of total dsRNAs from virions in 1.5% agarose gel (lane 1)and the corresponding Northern hybridization results (lane 2,3 and 4). The [32P]dCTP-labeling probes were prepared from the cDNAs of the corresponding dsRNA segments, and the total dsRNAs were transferred onto Hybond-N+ membrane in parallel and was used as the targets.

Supplementary-Table 1 Comparison of the 5′ and 3′ terminal sequences of AoR1 and AoR2 with those contained in Partitiviruses, such as P. stoloniferumvirusS (PsV-S), G.abietinaRNA virus MS1 (GaRV-MS1), G. abietinaRNA virus MS2 (GaRV-MS2), Discula destructivavirus 1 (DdV1) and D.destructivavirus 2 (DdV2). Identical nucleotides with those of AoR1 and AoR2 were marked in bold and with grayish background color.
