Abstract:
Pepper mild mottle virus (PMMoV) was detected by RT-PCR in all 42 pepper sauce samples from the 10 main manufacturing provinces in China at concentrations ranging from 3.8 to 8.8 (Log10 copies/mL). Their coat protein nucleotide sequences had 97.4 to 100 % identity to each other and 92.4 to 100 % to other published isolates. The samples remained infectious to N. benthamiana, indicating that commercial trade in sauce could contribute to the natural spread of PMMoV.
