Number of infected cells per cross section of tomato petioles infected by PepYVMLV DNA-A in single or mixed infection with DNA-B.

DNA-A and -B components were detected respectively using red- and green-FISH probes.
Values in brackets show the percentage of infected cells per detected component (DNA-A or -B) or components (DNA-A and -B).
dpi days post inoculation, NCSPA number of cross sections of petioles analysed.
p values were obtained from multiple comparisons of means of cell numbers between single and mixed infection cases using post-ANOVA Tukey HSD-test.
