“…A similar type of resistance was described for CMV whereby virus remained localized to the lower portions of the plant (54,156). Dufour et al (54) showed that CMV accumulated in external but not internal phloem in the petiole of the inoculated leaf and the lower stem of the resistant genotype. Derrick & Barker (44) evaluated potato lines resistant to Potato leafroll virus (PLRV) and showed that the resistance was associated with an exclusion of virus from external phloem bundles, whereas virus occurred in both internal and external phloem in the susceptible line.…”

“…Infection by a second virus, CMV, alleviated this restriction, which suggests that CMV was able to compensate for the defect in the host, either by providing a factor that facilitates movement of both viruses or alleviating the restriction by an unknown mechanism (151,228). A similar type of resistance was described for CMV whereby virus remained localized to the lower portions of the plant (54,156). Dufour et al (54) showed that CMV accumulated in external but not internal phloem in the petiole of the inoculated leaf and the lower stem of the resistant genotype.…”

Genetic resistance to plant viruses has been used for at least 80 years to control agricultural losses to viral diseases. To date, hundreds of naturally occurring genes for resistance to plant viruses have been reported from studies of both monocot and dicot crops, their wild relatives, and the plant model, Arabidopsis. The isolation and characterization of a few of these genes in the past decade have resulted in detailed knowledge of some of the molecules that are critical in determining the outcome of plant viral infection. In this chapter, we have catalogued genes for resistance to plant viruses and have summarized current knowledge regarding their identity and inheritance. Insofar as information is available, the genetic context, genomic organization, mechanisms of resistance and agricultural deployment of plant virus resistance genes are also discussed.

Nuclear RFLP between pepper cultivars (Capsicum annuum L.)

Forty one nuclear probes, distributed across the different linkage groups of the previously published map, were used to examine restriction fragment length polymorphism between cultivated peppers . Total DNA from thirteen accessions of Capsicum annuum var . annuum and one accession of C. baccatum var. pendulum was separately cut with ten restriction enzymes . The analyses were restricted to only one enzyme per probe to reduce the polymorphism redundancy. Nei & Li's genetic distances between accessions were calculated from the 141 resultant nuclear DNA restriction fragments . The genetic variation was larger between C . annuum and C. baccatum than between C. annuum cultivars . Large fruited related accessions closely clustered together .Distances between the small fruited cultivars were larger than within the bell pepper group . A correspondence analysis performed on differences between the global RFLP patterns of each accessions of C. annuum revealed the particular genomic structure of four small fruited cultivars : Criollo de Morelos 334, H3, Perennial and Doux Long des Landes . The percentage of probes revealing at least one RFLP with at least one enzyme ranged from zero to fifty percent for all the pairwise comparisons of C . annuum accessions . 82 presumptive loci were detected with a mean number of 1 .46 alleles per locus within C . annuum and 1 .83 within all the accessions . This result indicates that molecular markers will be more usable in intraspecific study of C.annuum than isozyme markers .

“…Overall, CMV had a strong synergistic effect on symptom development and yield when combined with the other two viruses. These results suggest that CMV-resistant cultivars (Dufour et al 1989;Caranta et al 2004) are beneficial even though they do not possess PepMoV or PMMoV resistance, through the prevention of a synergistic effect of CMV.…”

The patterns and progress of disease caused by multiple infections of Cucumber mosaic virus (CMV), Pepper mild mottle virus (PMMoV) and Pepper mottle virus (PepMoV) and their effects on growth of pepper plants (Capsicum annuum L.) were investigated in this study. Each virus induced distinct symptoms, but more severe symptoms, including reduced growth rates, were observed when pepper plants were simultaneously infected by more than one virus. When CMV was included in multiple viral inoculations, co-inoculations and sequential inoculations, PepMoV and PMMoV symptoms were observed but the symptoms characteristic of CMV were not masked, even though CMV titre did not increase greatly.In multiple viral infections, PepMoV titre and CMV did not increase significantly, but PMMoV titre gradually increased in most cases. Growth rates of pepper plants were greatly reduced during the 30 to 40-day postinoculation period under both single-infection and multiple-infection conditions, but multiple viral infections of CMV pre-inoculated peppers were affected to a greater extent. A significant reduction in fruit size and fruit number was observed in single and multiple viral inoculations, and fruit malformation rates were high in CMV single-infection and multiple viral infections with CMV.
