I have discovered 2 viruses in Galanthus nivalis. The plants didn't showed any symptoms. Cucumber Mosaic Virus (have more than 1000 hosts) and Lily Mottle Virus (probably, or maybe a newone), we tested the samples for CMV and potyviruses, but we didn't have had time for example Tobamoviruses, Potexviruses or Tospoviruses (TSWV has also around 1000 hosts). I have also read that some variegations may occure from viral infection, but most variegation is a kind of chimera. Jan
