Pepper yellow mosaic virus on Petunia hybrida, bean Viola odorata and Narcissus stripe cyclamineus were identified in Brazil using RT-PCR. Serology, mechanical transmission, host range, electron microscopy used to study the viruses further.

An isolate of chilli veinal mottle virus (ChiVMV; genus Potyvirus) Solanum nigrum L. from southwest China (ChiVMV-YunN/Yuxi) was identified and sequenced (GenBank: OP404087). Comparison with other ChiVMV isolates recombination analyses suggested a recombinant origin. The most significant event among all 21 complete an ending breakpoint at 1408–1488 for ChiVMV-YunN/Yuxi ChiVMV-TaiW ChiVMV-YunN/C...
