Biological properties of the S. sclerotiorum strain artificially infected by SsOLV4. Strains M6, N39, and N69 are the protoplasm-regenerants of strain PX14A4; strains N39P, N69P, and Ep-1PNA367P are the strains transfected by synthesized RNA. A synthesized virus was also transmitted to Ep-1PNA367 through hyphal anastomosis to obtain strains M6TA, N39PTA, N69PTA, and Ep-1PNA367PTA. (A) Colony morphology of strains (PDA, 14 days, 21°C). (B) Radial mycelial growth rate (PDA, 21°C). (C) Lesion diameter on rapeseed leaves (21°C). In each histogram, bars labeled with the same letters are not significantly different (p > 0.05) according to the least significant difference test.
