Pepper plant co-infected by two Tobacco etch virus variants expressing fluorescent markers.
Pepper plants were inoculated with two Tobacco etch virus (TEV) variants expressing a green (GFP) or a red (mCherry) fluorescent marker. These markers allow for the visual tracking of the infection, from foci of primary infection in the inoculated leaf until systemic infection. This plant, photographed 7 days post inoculation, has developed a systemic infection with both virus variants. The mosaic patterns reflect both the potyvirus tendency to exclude infection of other genotypes, and the intense competition for space during viral expansion (see Zwart et al., doi:10.1371/journal.ppat.1002122).
