“…Field experiments confirmed the economic feasibility of applying Caryophyllales extract in virus disease control. Zuchini plants treated with B. spectabilis and M. jalapa leaf extracts at cotyledon emergence and sprayed at 72 h intervals until flowering, achieved significantly higher fruit yield than that of control plants, even after ZYMV infection (Duarte et al, 2021).…”

“…Caryophyllales is one of the largest orders of eudicots (APG IV, 2016), with approximately 12,500 species distributed in 39 families (Hernández-Ledesman et al, 2015), including Nyctaginaceae and Phytolaccaceae, which contain species with widely-studied inhibitory activity against viral infection due to antiviral proteins (Grasso & Shepherd, 1978;Duarte et al, 2021). In addition to Bougainvillea spectabilis and Phytolacca thyrsiflora, which exhibited excellent results (Noronha et al, 1989;Duarte et al, 1990), viral inhibitors have been extensively studied only in Celosia argentea (Amaranthaceae), Dianthus caryophyllus (Caryophyllaceae), Boerhaavia difusa, Mirabilis jalapa and B. spectabilis (Nyctaginaceae) and Phytolacca americana (Phytolaccaceae) (Awasthi et al, 2015).…”

In Brazil, zucchini (Cucurbita pepo) is a socioeconomically important vegetable affected by damage caused primarily by zucchini yellow mosaic virus (ZYMV). Although the occurrence of cucumber mosaic virus (CMV) is less frequent, in C. pepo ‘Caserta’ plants it can cause symptoms such as mottle, mosaic, leaf and fruit distortion, as well as reduced plant development. To minimize the damage, the most widely used management technique is the preventive, albeit inefficient, application of insecticides, aimed at controlling aphids, the vectors of this virus. Thus, the search for more effective and less environmentally harmful control methods has been the target of investigations. The purpose of the present study was to assess the action of the extracts of four native Caryophyllales species, as inhibitors of infection by CMV and ZYMV in C. pepo, in addition to evaluating the possible induced resistance in this species. Fresh leaf extracts (LEs) of Guapira opposita, Pisonia ambigua (Nyctaginaceae), Gallesia integrifolia and Seguieria langsdorffii (Phytolaccaceae), previously assessed in the tobacco mosaic virus / Nicotiana glutinosa pathosystem, were submitted to progressive dilutions sprayed on cotyledonary C. pepo leaves 30 min before inoculation with CMV and ZYMV. Leaf extracts of G. integrifolia did not induce inhibition in any of the pathosystems assessed. Guapira opposita LEs inhibited the infection of plants inoculated with ZYMV below 50% but inhibited CMV infection by 70% at a concentration of 1:40. Given that leaf extracts of P. ambigua and S. langsdorffii induced high percentage inhibition, evident in the number of asymptomatic plants and confirmed by serological tests, these species were selected to assess induced resistance in pre-treatment experiments. The LEs were efficient in inhibiting ZYMV and CMV infection in C. pepo when applied up to 48 h before inoculation. The LEs of S. langsdorffii and G. opposita, also tested for this system, were efficient when applied up to 72 h before CMV inoculation. The LEs can be prepared from dry leaves and maintained at -20°C for at least three years, conserving their inhibitory activity. These results expand the possibilities for producers and consumers alike in the sustainable management of the main zucchini viruses, without damaging the environment.

Abstract. Listihani L, Yuniti IGAD, Sapanca PLY, Pandawani NP, Selangga DGW. 2023. The antiviral potential of macroalgae in suppressing Sweet potato leaf curl virus (SPLCV) infection in sweet potatoes. Biodiversitas 24: 4079-4086. Sweet potato leaf curl virus (SPLCV) was first found in sweet potatoes in Indonesia in 2022. Prevention of spread of virus is essential, especially by using macroalgae extract which is environmentally friendly and has antiviral activity. The aim of present research was to test the potential of sea macroalgae to suppress SPLCV infection and to analyze phytochemicals of potential macroalgae containing an antiviral substance. Macroalgae extract was sprayed on the test plants that were infected by SPLCV. The observed parameters were changes in symptoms, disease incidence and severity, virus confirmation by PCR, and phytochemical analysis. The test results up to day 21 showed that Eucheuma spinosum was found to be effective in suppressing SPLCV infection in sweet potatoes, up to symptomless infection in young leaves. E. spinosum and E. cottonii suppressed disease incidence by 80% and 40% and lower disease severity as much as 71% and 48%, while E. serra showed less ability to suppress SPLCV infection. The two macroalgae had flavonoid, saponin, and steroid content which may be the reason to suppress the viral infection. The results of PCR analysis showed that microalgal extract had the highest nucleotide and amino acid homology with Gianyar (LC586170) isolate with values of 99.7 and 100%. The macroalgae with the highest ability to suppress the virus were E. spinosum and E. cottonii. This showed that the application of macroalgae extract did not change the amino acid sequence of SPLCV isolate.

“…By inducing the defence mechanism in vulnerable hosts, the glycoprotein promotes the plant system to produce new proteins 12 , and it prevents viral infection by impeding virus replication 13 . Strong antiviral activity was found in the sap that was extracted from the leaves of host plants sprayed with Boerhaavia diffusa glycoprotein 14 . On the other hand, Waziri 10 found that no similar activity was seen in the sap of the untreated control plants.…”

Evaluate the impact of extracts from the Lens culinaris plant on a number of physiological and biochemical parameters in squash leaves infected with ZYMV in this work. Compared to the untreated leaves, ZYMV infected leaves showed a range of symptoms, such as severe mosaic, size reduction, stunting, and deformation. Analysis of physiological data revealed that L. culinaris extract lectin therapies and viral infections had an impact on metabolism. Protein, carbohydrate, and pigment levels were all lowered by viral infection. However, phenolic compounds, total protein, total carbohydrates, total amino acids, proline, total chlorophyll and peroxidases levels are considerably elevated with all extract therapies. The other biochemical parameters also displayed a variety of changes. Moreover shoot length, number of leaves and number of flowers was significantly increased compared to viral control in all treatments. The L. culinaris extract treatment increases the plant’s ZYMV resistance. This is detectable through reduction of the plants treated with lentil lectin pre and post virus inoculation, reduction in disease severity and viral concentration, and percentage of the infected plants has a virus. All findings demonstrate significant metabolic alterations brought by viral infections or L. culinaris extract treatments, and they also suggest that exogenous extract treatments is essential for activating the body’s defences against ZYMV infection.
