Abstract: Physalis angulata L. is an annual herb of Solanaceae. Among several biological activities described for this species, its cytotoxic action is due to the presence of flavonoids. Natural infection of P. angulata by Potato virus Y, strain O (PVY O ), has already been described. The main goal of this study is to verify whether PVY O infection influences the secondary metabolism of P. angulata, evaluating total amount of phenolic compounds and the content and profiles of flavonoids. Twenty-day-old plants were distr… Show more

“…The obtained results indicated a reduction in both phenolic and flavonoid contents (42.8 ± 1.5 and 11.5 ± 0.8 mg/g d. wt, respectively) in CMV treatment compared to Mock plants (76.7 ± 9.1 and 13 ± 1.2 mg/g d. wt, respectively) which is in line with the free radical scavenging activity ( Figure 7 B,C). The reduction of phenolic and flavonoid contents was reported among the main traits for several viral plant infections [ 73 , 74 ] and could be attributed to viral suppressor activity and severe mosaic symptoms [ 75 ]. The treatment with Ag-NPs revealed parallel impacts on phenolic and flavonoid contents, where the pre-CMV treatment significantly enhanced both contents to 72.1 ± 9.7 and 13.9 ± 2.1 mg/g d. wt.…”
