“…20mM H 2 O 2 application followed by infection caused a 67% increase in proteins than control because of the double source of induction: treatment and infection. Proteins are among the main types of anti-plant viral substances [51]. Plants form certain proteins upon infection (pathogenesis-related proteins) to restrict pathogen growth and multiplication [52].…”

The aim of this work was to study the effects of hydrogen peroxide (H 2 O 2) application against cucumber green mottle mosaic virus (CGMMV) infection in watermelon (Citrullus lanatus) plants. From the obtained results, the induced resistance using H 2 O 2 treatments caused a delay in the appearance of CGMMV symptoms in watermelon plants. The viral infection showed abnormal morphological symptoms such as mosaics, yellow blisters and reduction in size. Pretreatment with H 2 O 2 before infection was beneficial in increasing the contents of pigments, total proteins, total free amino acids and proline. Consequently, plants appeared morphologically similar to healthy controls. Signaling the effect of the H 2 O 2 treatment could induce partial resistance or delay the appearance of symptoms and decreased virus concentration. The induced mechanism of resistance was suggested to be through alterations of plant antioxidant status-both enzymatic and non-enzymatic. All analyzed antioxidant enzymes were induced in response to H 2 O 2 ±CGMMV. due to the H 2 O 2 application prior to infection, malondialdehyde (MdA) content was reduced, indicating a lowering in lipid peroxidation caused by virus infection. On the other hand, internal H 2 O 2 and phenolics contents were induced in H 2 O 2 + CGMMV-treated leaves. To confirm: total antioxidant activity was increased to be double the value (80.67%) of that recorded in healthy plants (47.18%), indicating changes in antioxidant status as a response to H 2 O 2 and/or CGMMV infection. This work provided evidence of the signaling role of exogenous H 2 O 2 , which led to systemic acquired resistance (SAR) induction acting against CGMMV infection in watermelon plants. From the present findings, a suggestion of spraying of H 2 O 2 might be helpful in avoiding the appearance of CGMMV severe symptoms throughout the plants' life.

“…Unlike diseases induced by fungi and bacteria, viral diseases are difficult to control once the plants are infected (Hadidi & Barba, ). Over recent decades, various strategies have been developed to control viral diseases, including the breeding of virus‐resistant/tolerant cultivars by classic breeding techniques (Wang et al , ) and genetic transformation (Prins et al , ), the use of virus‐free plant materials (Laimer & Barba, ), the control of virus‐transmitting vectors (Zhao et al , ), and chemical priming to induce the resistance/tolerance of existing cultivars to viruses (Zhao et al , ; Iriti & Faoro, ; Lu et al , ).…”

In this study, melatonin (MEL)‐mediated plant resistance to tobacco mosaic virus (TMV) was examined to study local infection in Nicotiana glutinosa and systemic infection in Solanum lycopersicum. Exogenous application of 100 µm MEL increased anti‐virus infection activity to 37.4% in virus‐infected N. glutinosa plants. The same treatment significantly reduced relative levels of virus RNA analysed by qRT‐PCR and virus titres measured by dot‐ELISA, and increased the relative expression levels of the PR1 and PR5 genes analysed by qRT‐PCR, in virus‐infected S. lycopersicum. MEL treatment induced considerable accumulations of salicylic acid (SA) and nitric oxide (NO) but did not significantly affect production of hydrogen peroxide (H2O2) in the virus‐infected S. lycopersicum plants. Transgenic nahG N. tabacum was used to determine whether MEL‐induced TMV resistance was dependent on the SA pathway. The results showed that the relative RNA level of the TMV analysed by qRT‐PCR and virus titres analysed by dot‐ELISA were not reduced by the MEL treatment in the nahG transgenic N. tabacum seedlings treated twice with 100 µm MEL. The increased relative expression levels of PR1 and PR5 were greatly reduced when cPTIO, an NO scavenger, was included in the MEL treatment. A working model of MEL‐mediated plant resistance to TMV is proposed. MEL‐mediated plant resistance to viruses provides a new avenue to control plant viral diseases.

“…Plant viral diseases cause great damage to the agricultural industry. Studies show that proteins, polysaccharides and small molecules (alkaloids, flavonoids, phenols, essential oils), produced by plants, can potentially control plant viral diseases (reviewed by Zhao et al ., ). For example, sulphated lentinan of Lentinus edodes (Wang et al , ) and essential oil extracted from Satureja montana (Dunkić et al ., ) have inhibitory effects on tobacco mosaic virus (TMV) infection.…”

Crude garlic extract significantly inhibits replication of grapevine viruses

Efforts to control viral diseases of grapevine include the production of certified material and development of virus‐resistant transgenic grapevines. However, effective antiviral agents, once the viruses have infected the plants, are still lacking. This study shows that a crude garlic extract has significant antiviral activity against grapevine viruses. Replication of grapevine leafroll‐associated virus 2 (GLRaV‐2) was obviously inhibited in grapevine cv. Cabernet Sauvignon calli treated with diluted (1:100) garlic extract. The relative RNA levels of GLRaV‐2 and grapevine fleck virus (GFkV) in cv. Summer Black grapevine in in vitro‐grown plantlets 10 days after treatment with diluted (1:100) garlic extract were about 22% and 20%, respectively, of that in controls. The viral RNA accumulation of GLRaV‐2, GFkV, grapevine virus A (GVA), grapevine fanleaf virus (GFLV) and grapevine rupestris stem pitting‐associated virus (GRSPaV) in field‐grown grapevine cv. Centennial Seedless plants sprayed with diluted (1:100) garlic extract were about 31–40%, 26–38%, 18–31%, 17–42% and 15–18%, respectively, of that in controls. Moreover, the garlic extract treatment led to a significant decrease in viral RNA accumulation of GLRaV‐3, GLRaV‐2, GVA, GFkV, GFLV, GRSPaV and grapevine Pinot Gris virus in pot‐grown grapevine cv. Shine Muscat plants, and viral disease symptoms in these plants were obviously attenuated. In addition, this extract significantly induced expression of pathogenesis‐related protein genes and stimulated activity of antioxidant enzymes in grapevines. Taken together, these results indicate that the crude garlic extract acts as a significant inhibitor against a broad range of grapevine viruses.
