Size distribution analysis of the fluorescent infection foci produced by RNA transcripts generated from pBYV-GFP and its variants, possessing mutations in the HSP70h ORF at 12 d.p.i. (A) Comparison between the parental BYV variant (BYV-GFP, derived from pBYV-GFP cDNA clone) and six mutant variants (see the text for further explanation). Because all the mutants exhibited identical movement-deficient phenotypes, the corresponding data were combined. (B) Comparison between the three revertant variants in which the original mutations were changed back to the wild-type (“Yes”) variants and parental mutant variants. Because all revertants exhibited identical movement-competent phenotypes, the corresponding data were combined. n, number of analyzed infection foci.
