“…Like other solanaceous plants, physalis is also affected by virus diseases. To date, ve viruses have been reported to naturally infect P. peruviana in Brazil: the Sobemovirus physalis rugose mosaic virus (PhyRMV) (Fariña et al 2019), the Potyviruses potato virus Y (PVY), and pepper yellow mosaic virus (Esquivel-Fariña et al 2022) and the Orthotospoviruses tomato chlorotic spot virus and groundnut ringspot virus (GRSV) (Eiras et al 2012;Fariña et al 2018).PhyRMV causes severe leaf mosaic symptoms, malformation, leaf abscission, and reduced plant development (Kraide et al 2023). Additionally, infected plants have yield reduction varying from 66% to 70%, and some postharvest fruit characteristics are negatively affected (Gorayeb et al 2020; Kraide et al 2023).…”

Physalis peruviana (Solanaceae) is an exotic plant in Brazil that has been increasingly known for its fruits’ vitamins, nutrients, and high-added value. Like other solanaceous plants, physalis is also the target of some plant viruses; until now, five viruses have been reported to naturally infect P. peruviana in Brazil. Among them, the physalis rugose mosaic virus (PhyRMV) has attracted attention due to the severity of the symptoms, characterized by leaf mosaic, malformation, leaf abscission, and a significant reduction in plant development and yield. This work evaluated the efficiency of different forms of PhyRMV transmission. The virus was efficiently transmitted to healthy physalis plants through contact between the leaves, pruning, and contaminated soil. PhyRMV remained active and infectious in contaminated soil for up to ninety days.

“…Viruses have gained attention due to their high incidence and difficulty in controlling their infections. In Brazil, five viruses have been found to naturally infect Physalis plants: two belonging to the genus Orthotospovirus , tomato chlorotic spot virus and groundnut ringspot virus (GRSV) (Eiras et al, 2012; Fariña et al, 2018), two belonging to the genus Potyvirus , potato virus Y (PVY) and pepper yellow mosaic virus (Esquivel‐Fariña et al, 2022), and one in the genus Sobemovirus , physalis rugose mosaic virus (PhyRMV), which has been reported in high incidences in the states of Santa Catarina, Paraná and São Paulo (Fariña et al, 2019).…”

Effects of physalis rugose mosaic and groundnut ringspot viruses, in single and double infections, on the development, yield and postharvest fruit characteristics of Physalis peruviana plants

Physalis peruviana (Solanaceae), originating from the Andean region of South America, is an exotic plant cultivated in Brazil that produces edible fruit. Five viruses have been reported to naturally infect the Physalis plants in Brazil, of which, two have been drawing attention for the severity of their infections: sobemovirus, physalis rugose mosaic virus (PhyRMV) and orthotospovirus, groundnut ringspot virus (GRSV). This study aimed to evaluate the effects of single and double infections of PhyRMV and GRSV on the development, yield and postharvest fruit characteristics of P. peruviana plants. We found that both viruses caused severe systemic symptoms in infected plants, and double infection even led to plant death. Plant height and aerial dry weight were significantly affected by PhyRMV and GRSV infections. Double‐infected plants were the most affected, exhibiting average height and aerial dry weight reductions of 70.9% and 89.7%, respectively. Moreover, PhyRMV‐ and GRSV‐infected plants showed average fruit yield reductions of 66.4% and 85.2%, respectively, compared to healthy plants. Notably, double‐infected plants did not produce any fruit. The fruits produced by infected plants were smaller than those produced by healthy plants. Viral infections also affected postharvest characteristics, such as titratable acidity, total soluble solids (°Brix), phenolic compound concentration and antioxidant activity. Both viruses affected the pulp firmness and palatability, but not the colour of the fruits. Therefore, effective disease management strategies against these viruses are necessary to prevent economic losses.
