Phenotypical alteration of VIGS-mediated silencing of PhNF-YC2 and PhNF-YC4 in petunia. (a) Phenotypes of VIGS-mediated PhNF-YC2-silenced plants and PhNF-YC4-silenced plants at 50 days and 95 days after infection; (b) relative expression levels of PhNF-YC2 in control plants and PhNF-YC2-silenced plants; (c) relative expression levels of PhNF-YC4 in control plants and PhNF-YC4-silenced plants; (d) average total chlorophyll content of control plants and PhNF-YC2-silenced plants. Three independent experiments were performed, and error bars indicate standard deviation. * and **** indicate significant differences from the relative expression or chlorophyll content of control plants (TRV-CHS) at p-values < 0.05 and 0.0001, respectively.
