“…The main transmission route of the virus is Bemisia tabaci infection [4]. TYLCV can infect Solanaceae, Cucurbitaceae, and Piperaceae plants, such as tomato [5], cucumber [6], and pepper [7], and with the greatest harm to tomato. Because the virus is parasitic in plants, which lack an animal-like intact immune system, plants’ lives are endangered upon viral infection.…”

Background: In higher plants, salicylic acid (SA) plays important roles in inducing resistance to biotic and abiotic stresses. Tomato yellow leaf curl virus (TYLCV) causes a highly devastating viral disease in plants, particularly in tomato. However, the roles of SA in inducing tomato plant resistance to TYLCV remain unclear. Results: In this study, we investigated whether the exogenous application of SA can improve the resistance of tomato plants to TYLCV in two tomato cultivars, resistant 'Zhefen-702' and susceptible 'Jinpeng-1'. The impacts of SA on the accumulation of ascorbic acid (AsA) and biosynthetic gene expression, the activity of some important reactive oxygen species (ROS)-scavenging enzymes, and the expression patterns of stress-related genes were also determined. Results indicated that SA can effectively regulate the accumulation of AsA, especially in 'Jinpeng-1'. Similarly, the expression patterns of most of the AsA biosynthetic genes showed a negative relationship with AsA accumulation in the resistant and susceptible tomato cultivars. In the two tomato cultivars, the activities of ascorbate peroxidase (APX) and peroxidase (POD) in the SA + TYLCV treated plants were increased during the experiment period except at 14 days (APX in 'Jinpeng-1' was also at 4 days) post infected (dpi) with TYLCV. Simultaneously, the activity of SOD was reduced in 'Jinpeng-1' and increased in 'Zhefen-702' after treatment with SA + TYLCV. SA can substantially induce the expression of ROS-scavenging genes at different extents. From 2 to 10 dpi, the virus content in the SA + TYLCV treated plants was remarkably lower than those in the TYLCV treated plants in 'Jinpeng-1'and Zhefen-702'. Conclusions:The above results suggest that SA can enhance tomato plant resistance by modulating the expression of genes encoding for ROS-scavenging players, altering the activity of resistance-related enzymes, and inducing the expression of pathogenesis-related genes to produce systemic acquired resistance. Simultaneously, these results confirm that SA is a resistance-inducing factor against TYLCV infection that can be effectively applied in tomato plants.

“…The sequence 1TQT_N shared its highest nt sequence identity of 96.7% with a TYLCV isolate (GU076454) of the “Boushehr” strain infecting tomatoes in Iran [ 24 ]. Other sequences shared their highest nt sequence identities of 95.3–97.2% with the TYLCV isolate (KR108214) of the “Iran” strain infecting cucumbers in Kuwait [ 25 ]. In the phylogenetic dendrogram, all these isolates shared the same well-supported clades with other TYLCV isolates of the “Boushehr” and “Iran” strains ( Figure 2 A).…”

The studies on the prevalence and genetic diversity of begomoviruses in Saudi Arabia are minimal. In this study, field-grown symptomatic tomato and muskmelon plants were collected, and initially, begomovirus infection was confirmed by the core coat protein sequences. Four tomato and two muskmelon plants with viral infections were further evaluated for Illumina MiSeq sequencing, and twelve sequences (2.7–2.8 kb) equivalent to the full-length DNA-A or DNA-B components of begomoviruses were obtained along with eight sequences (~1.3–1.4 kb) equivalent to the begomovirus-associated DNA-satellite components. Four begomovirus sequences obtained from tomato plants were variants of tomato yellow leaf curl virus (TYLCV) with nt sequence identities of 95.3–100%. Additionally, two tomato plants showed a mixed infection of TYLCV and cotton leaf curl Gezira virus (CLCuGeV), okra yellow crinkle Cameroon alphasatellite (OYCrCMA), and okra leaf curl Oman betasatellite (OLCuOMB). Meanwhile, from muskmelon plants, two sequences were closely related (99–99.6%) to the tomato leaf curl Palampur virus (ToLCPalV) DNA-A, whereas two other sequences showed 97.9-100% sequence identities to DNA-B of ToLCPalV, respectively. Complete genome sequences of CLCuGeV and associated DNA-satellites were also obtained from these muskmelon plants. The nt sequence identities of the CLCuGeV, OYCrCMA, and OLCuOMB isolates obtained were 98.3–100%, 99.5–100%, and 95.6–99.7% with their respective available variants. The recombination was only detected in TYLCV and OLCuOMB isolates. To our knowledge, this is the first identification of a mixed infection of bipartite and monopartite begomoviruses associated with DNA-satellites from tomato and muskmelon in Saudi Arabia. The begomovirus variants reported in this study were clustered with Iranian isolates of respective begomovirus components in the phylogenetic dendrogram. Thus, the Iranian agroecological route can be a possible introduction of these begomoviruses and/or their associated DNA-satellites into Saudi Arabia.

“…However, none of the potato tuber samples tested were found to be infected with Potato Leaf Curl Virus (PLRV). Al- Ali et al (2016) reported that 45 out of 50 plants were infected with TYLCV after testing with DAS-ELISA method for symptoms such as upward curling, chlorosis, mosaic, dwarfing in plants and deformation in fruits and leaves, one of the most important vegetables grown in Kuwait. The existence of TYLCV in our country was determined by Yilmaz (1978).…”

Surveys were conducted at tomato production sites in Adana province in 2019. 53 tomato plants have been collected showing the virus symptom due to determining its prevalence. The collected samples were tested for 13 different viral agents harmful to tomatoes using ELISA and RT-PCR methods. 24.52% TYLCV and 9.43% PLRV were detected from the tested samples. When DNA sequencing comparisons are made from RT-PCR products, 98,74% of PLRV isolates in tomato samples collected from Adana province are homogical similarity with Belgium potato isolate (KX364206.1). Also it clustered at 99.37% similar to same branch with New Zealand (GU002341.1) (BLAST at NCBI).
