Abstract

In the eyes of a tomato grower, resistance to TYLCV, as opposed to susceptibility, is defined by the absence of, or mild, disease symptoms, and acceptable yield. In resistant cultivars and breeding lines, the amount of virus that can be detected with molecular tools is usually smaller than that in the susceptible plants, especially during the first 4 weeks after inoculation. Genetic studies have indicated that several genes, expressed as quantative trait loci (QTL), are involved in providing the resistance phenotype described above. Several QTLs have been localized to tomato chromosomes using polymorphic DNA markers (see Part V, Chapter 2). However, the molecular basis of resistance to TYLCV remains totally unknown. Moreover, the physiological state of susceptible vs. resistant plants, before and after inoculation, has never been compared.
