The viral etiology of tomato yellow leaf curl disease, . Tomato yellow leaf curl virus (TYLCV) is one of the most studied plant viral pathogens because it is the most damaging virus for global tomato production. On the contrary, TYLCV counteracts cell death induced by other factors, such as inactivation of HSP90 functionality. Sci. Sci. plants resistant to ToLCV (Paduchuri et al., the SL2.50 tomato genome assembly with either, species introgression and provides robust molecular marker development and potential, transformation of an inbred tomato line with the ToLCV nucleoprotein gene, cassette produced high levels of resistance to the virus which was maintained in, cultivars derived from wild species by incorporation of tomato breeding (U, (Rep) gene was used to transform genotypes. The tomato leaf curl New Delhi virus (ToLCNDV) (genus Begomovirus, family Geminiviridae) represents an important constraint to tomato production, as it causes the most predominant and economically important disease affecting tomato in the Indian sub-continent. The evaluation of ToLCNDV infection in a variety of hosts differing in their tolerance and identification of differentially expressed genes would be helpful in speculating the threats associated with similar begomoviral invasions. Ioannou, N. (1985) Yellow leaf curl and other virus disease of tomato in Cyprus.

Using bulk segregant analysis (BSA) and one of the F2populations (‘PBC’ �‘EC-520061’) above, two SSR markers (SSR218170-145and SSR304158-186) were identified for ToLCV resistance. . Curling tomato leaves may be a sign of a viral infection. In addition, grafting experiments using infected susceptible scions grafted onto TY172 stocks, showed that even when exposed continuously to very high levels of virus, line TY172 did not develop disease symptoms, nor did it accumulate high levels of the virus. . and utilization of conserved ortholog set markers for comparative genomics in higher. When pathogen enters the plant system, diverse defense responses are initiated which are mediated by plant disease resistance genes (R genes) mediated resistance and hormone based signaling pathways which restrict the viral spread by initiating hypersensitive response. Singh, and D.P. Tomato yellow leaf curl disease (TYLCD) is one of the most significant viral diseases infecting tomato and causes severe economic losses worldwide. The quantification of total phenol and sugar along, ). 85(7):896, Brien J. In order to combat this global threat, it is important that we understand the biology of TYLCV and devise management approaches. Veg. Tahir. Limited resistance genes have been iden-, ) against TYLCV, and its alleles have been, to identify resistant genotype which is possible using wild genetic resources, , but there is limited information available regarding, resistance in tomato. A saturated linkage map of, derived from crosses of closely related species and crosses within, phenotyping of populations is easier, and/or, cheaper than genotyping using DNA, marker assays. HortScience 37(3):603. Each population displayed the additive and dominant gene action according to their heritability for using characters. Proceedings of the whitefly-borne geminivirus of tomato. On the basis of visual observation of fruit colour, deep red and green colours in the crosses of S. pimpinellifolium (EC 521080) and S. habrochaites (EC 520061) exhibited dominant effects.
