“…Their findings revealed overall similar metabolic changes in the leaves under viral stress, which is consistent with our results. Various metabolite markers have been identified in different studies that investigated the alteration of plant metabolome under geminivirus infection Donati et al, 2022) . Additionally, a similar set of 1H NMR peaks for legume plant metabolome has been previously reported in several studies (Chen et al, 2019;Bueno and Lopes, 2020;Villa-ruano et al, 2021).…”

Plant viruses exert control over the host metabolism to enhance their survival, but the specific sites where altered metabolites take effect remain enigmatic. This study focuses on the apoplastic region of symptomatic mungbean leaves infected with mungbean yellow mosaic India virus (MYMIV) to gain new insights into metabolite changes during infection. Leveraging NMR-based metabolome fingerprinting, we identified several stress-associated metabolites. Notably, proline and 2-Hydroxybutyrate were found to be up-regulated in the apoplast region, while down-regulated in the cytosol. Additionally, aspartate was found to be upregulated in the cytosolic region but absent in the apoplast. Importantly, our molecular analysis of the apoplast suggests the presence of MYMIV genomic components. Moreover, we characterized two distinct populations of extracellular vesicles (EVs) using ultracentrifugation, transmission electron microscopy, dynamic light scattering, and fluorometric assays. The data revealed alterations in the size and count of EVs, suggesting their potential role in facilitating the transport of viral components for long-distance cell-to-cell movement during infection. These findings provide valuable insights into the apoplast's role and the significance of EVs in MYMIV infection, contributing to a better understanding of virus-host interactions and potentially informing new virus defense strategies.

“…Natural plant bio-stimulants can be used as environmentally friendly alternatives to agricultural chemicals. A recent study reported that such bio-stimulants (e.g., Fullcrhum Alert and BioVeg 500) affected the fitness of zucchini plants against ToCLNDV (Donati et al 2022 ). Essential oils (EOs) and hydrosols (HS) derived from natural plant products have also gained attention.…”

Tomato leaf curl New Delhi virus (ToLCNDV), a bipartite begomovirus, was first reported to infect tomato and has recently spread rapidly as an emerging disease to Cucurbitaceae crops. To date, the virus has been reported to infect more than 11 cucurbit crops, in 16 countries and regions, causing severe yield losses. In autumn 2022, ToLCNDV was first isolated from cucurbit plants in Southeastern coastal areas of China. Phylogenetic analysis established that these isolates belong to the Asian ToLCNDV clade, and shared high nucleotide identity and closest genetic relationship with the DNA-A sequence from the Chinese tomato-infecting ToLCNDV isolate (Accession no. OP356207) and the tomato New Delhi ToLCNDV-Severe isolate (Accession no. HM159454). In this review, we summarize the occurrence and distribution, host range, detection and diagnosis, control strategies, and genetic resistance of ToLCNDV in the Cucurbitaceae. We then summarize pathways that could be undertaken to improve our understanding of this emerging disease, with the objective to develop ToLCNDV-resistant cucurbit cultivars.

“…Zeolite foliar treatments showed interesting results on grapevines for containing fungal diseases [ 17 ], on apple trees [ 18 ], and olive trees in conditions of water stress [ 19 ]. A combination of organic biostimulants with an inorganic corroborant (zeolite) was also tested for the plant response to the quarantine pest tomato leaf curl New Delhi virus [ 20 ].…”

The olive fruit fly (Bactrocera oleae Rossi) is the most dangerous pest of olive fruits and negatively influences the chemical and sensory quality of the oil produced. Organic farms have few tools against this pest and are constantly looking for effective and sustainable products such as geomaterials, i.e., zeolite. Since a particle film covers the canopy, a study was carried out on the olive tree’s responses to zeolite foliar coating. The tested treatments were natural zeolite (NZ), zeolite enriched with ammonium (EZ), and Spintor-Fly® (SF). EZ was associated with higher photosynthetic activity with respect to the other treatments, while no differences were found between SF and NZ. Foliar treatments affect the amount of BVOC produced in both leaves and olives, where 26 and 23 different BVOCs (biogenic volatile organic compounds) were identified but not the type of compounds emitted. Foliar treatment with EZ significantly affected fruit size, and the olive fruit fly more frequently attacked the olives, while treatment with NZ had olives with similar size and attack as those treated with Spintor-Fly®; no difference in oil quantity was detected. Oil produced from olives treated with NZ presented higher values of phenolic content and intensities of bitterness and spiciness than oils from those treated with EZ and SF. According to the results of this study, using zeolite films on an olive tree canopy does not negatively influence plant physiology; it has an impact on BVOC emission and the chemical and sensory characteristics of the oil.
