Most notably, MP(TVCV), but not MP(TMV), targets the nucleus and induces the formation of F actin-containing filaments that associate with chromatin. I recently showed that, despite belonging to the same genus, the behavior of the 2 viruses MPs differ significantly during infection.
However, since TMV does not infect the model plant Arabidopsis thaliana I have used a related Tobamovirus, Turnip vein-clearing virus (TVCV). The Tobamovirus, Tobacco mosaic virus (TMV) has served as the model virus to study the activities of single MPs. Plant viruses' cell-to-cell movement requires the function of virally encoded movement proteins (MPs).
Turnip vein clearing virus movement protein nuclear activity: Do Tobamovirus movement proteins play a role in immune response suppression? Based on published data and latest information, this is the first report of identification of Tomato yellow leaf 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. 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 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. 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 full DNA-A genome was found to have 2785 nucleotides with 1365Â bp-associated betasatellite molecule.
The full-length viral genome and betasatellite were amplified, cloned, and sequenced bidirectionally. 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 M. During farmers' field survey, yellow vein mosaic disease was observed in Mentha longifolia plants growing near tomato fields in Saudi Arabia. Begomoviruses are whitefly-transmitted viruses causing serious disease in many important plants exhibiting variable symptoms with significant economic loss globally. Mentha is a very important crop grown and used extensively for many purposes in the Kingdom of Saudi Arabia. Identification of a monopartite begomovirus associated with yellow vein mosaic of Mentha longifolia in Saudi Arabia.
