Biological properties of four individual strains: SZ-150/A6, SZ-150/R59, SZ-150/R6, and SZ-150. (A) Detection of mycoviruses Sclerotinia sclerotiorum hypovirus 1 (SsHV1/SZ-150) and its related satellite RNA (SatH), Sclerotinia sclerotiorum mycotymovirus 1 (SsMTV1/SZ-150), and Sclerotinia sclerotiorum botybirnavirus 3 (SsBV3/SZ-150) in four strains by RT-PCR. The actin gene served as an internal control. (B) Colony morphology and (D) growth rate of four individual strains. Four strains were grown on PDA for 15 days at 20C prior to photography. (C,E) Virulence assays of the four strains on the detached leaves of rapeseed plants. Statistical analysis of the growth rate and lesion diameter of the four individual strains was conducted at the P < 0.01 level. The error bars indicate the SD from three sample means.
