“…Earlier, in mentha, reports have indicated the presence of various classes of viruses, including a hordeivirus [1], Strawberry latent ringspot virus [33], Mint virus X [34] and a vitivirus [35], all reports emanating from the USA. Recently, a partial DNA sequence of a geminivirus related to Tomato leaf curl Pakistan virus was reported from mentha from Uttar Pradesh [27]. This investigation has provided evidence for the presence of a second tomato-infecting begomovirus (ToLCKV-Ban) in mentha.…”

A widespread leaf deformity disease of mentha (mint), accompanied by whiteflies, the vectors of begomoviruses, was observed in Punjab in the last few years. The presence of begomovirus was indicated by DNA dot-blot analysis using the conserved coat protein and replicationassociated protein genes of another begomovirus, Sri Lankan cassava mosaic virus (SLCMV). A DNA fragment (2.0 kb), representing a partial genomic DNA of a begomovirus, amplified from the symptomatic mentha leaves was used to design end-primers and further amplify an additional 0.9 kb fragment, representing the remaining portion of the resident viral DNA. The two sequences, assembled together (2.7 kb), showed that they represented the complete sequence of an isolate of Tomato leaf curl Karnataka virus (ToLCKV) DNA. Using universal betasatellite primers, a 1.4 kb fragment was amplified from the same sample. This cloned DNA fragment showed complete sequence identity with the previously reported Cotton leaf curl Multan betasatellite (CLCuMB). Majority of the symptomatic mentha leaf samples, collected from four districts of Punjab, showed cross-hybridization in DNA dot-blot using cloned SLCMV and CLCuMB DNA, indicating the presence of one or more begomoviruses related to SLCMV and the betasatellite, CLCuMB. The begomovirus and betasatellite could be mechanically transmitted to Nicotiana benthamiana. Whitefly transmission of the resident begomovirus could also be demonstrated on mentha. The evidence indicates the association of ToLCKV and CLCuMB, a hitherto new combination of a begomovirus and a betasatellite associated with a leaf deformity disease in mentha in Punjab.

“…Recently, the natural occurrence of begomovirus-caused disease in many crops like Amaranthus, Beans, Cucurbits, Okra, Tomato, and Corchorus has been reported in Saudi Arabia (Idris et al 2012;Al-Saleh et al 2014a, b;Sohrab 2016Sohrab , 2017Sohrab et al 2016aSohrab et al , b, c, d, e, 2017a. Globally, many viruses have been reported from mint species (Tzanetakis et al 2010) and the natural occurrence of begomoviruses on mint species has been reported as Tomato leaf curl Pakistan virus (Samad et al 2008), Tomato leaf curl Karnataka virus, Cotton leaf curl Multan virus (Borah and Dasgupta 2012), Chilli leaf curl India virus, Ageratum yellow vein virus betasatellite (Saeed et al 2014. Based on the published information on natural occurrence of begomoviruses on various crops in the Kingdom, this work was conducted to identify the association of virus with yellow vein mosaic disease of M. longifolia.…”

Mentha is a very important crop grown and used extensively for many purposes in the Kingdom of Saudi Arabia. Begomoviruses are whitefly-transmitted viruses causing serious disease in many important plants exhibiting variable symptoms with significant economic loss globally. During farmers' field survey, yellow vein mosaic disease was observed in plants growing near tomato fields in Saudi Arabia. The causative agent was identified in 11 out of 19 samples using begomovirus-specific primers and the association of begomovirus with yellow vein mosaic disease in was confirmed. The full-length viral genome and betasatellite were amplified, cloned, and sequenced bidirectionally. The full DNA-A genome was found to have 2785 nucleotides with 1365 bp-associated betasatellite molecule. An attempt was made to amplify DNA-B, but none of the samples produced any positive amplicon of expected size which indicated the presence of monopartite begomovirus. The sequence identity matrix and phylogenetic analysis, based on full genome showed the highest identity (99.6%) with Tomato yellow leaf curl virus (TYLCV) and in phylogenetic analysis it formed a closed cluster with Tomato leaf curl virus infecting tomato and Corchorus crop in Saudi Arabia. The sequence analysis results of betasatellites showed the highest identity (98.9%) with Tomato yellow leaf curl betasatellites infecting tomato and phylogenetic analysis using betasatellites formed a close cluster with Tomato yellow leaf curl betasatellites infecting tomato and Corchorus crops, which has already been reported to cause yellow vein mosaic and leaf curl disease in many cultivated and weed crops growing in Saudi Arabia. The identified begomovirus associated with yellow vein mosaic disease in mentha could be a mutated strain of TYLCV and tentatively designated as TYLCV-Mentha isolate. Based on published data and latest information, this is the first report of identification of Tomato yellow leaf curl virus associated with yellow vein mosaic disease of from Saudi Arabia.
