“…Regarding the resistant rootstocks, ÔGF677Õ was described as susceptible to Dideron-type PPV isolates by Breniaux et al (1990), although the findings here agree with results obtained by Audergon et al (1995). In addition, Rubio et al (2003) reported the resistance of different almond cultivars to PPV-D, and Martı´nez-Go´mez et al (2004) the successful transmission of this resistance to almond · peach hybrids. On the other hand, Dosba et al (1994b) indicated resistance to PPV Dideron and Marcus isolates of P. cerasifera clones, however Pascal et al (2002) described great susceptibility of clones of this species to PPV-M isolates.…”

Sharka (Plum pox virus, PPV) severely affects the production of most Prunus species in the areas affected by the disease. In this study, the resistance of 15 Prunus rootstocks to a Dideron type isolate of PPV was evaluated under controlled conditions in an insect-proof greenhouse. After four cycles of study, ÔGF677Õ almond · peach hybrid, ÔMyrobolan 29CÕ plum and ÔL2Õ cherry did not show any symptoms and were ELISA-DASI and RT-PCR negative. These were considered resistant to PPV. The rest of the rootstocks assayed showed symptoms of sharka (confirmed by ELISA-DASI or RT-PCR), although the level of susceptibility was different for each rootstock. ÔGF305Õ peach, ÔPuebla de SotoÕ plum and ÔReal FinoÕ apricot, were highly susceptible to PPV, showing strong sharka symptoms and being ELISA and RT-PCR positive. ÔMarianna 2624Õ plum, ÔAC 9921-07Õ hybrid and ÔCP-2Õ plum showed susceptibility to PPV confirmed by ELISA-DASI and RT-PCR positives. ÔNemaguardÕ and ÔNemaredÕ hybrids, ÔTorinelÕ plum and ÔSTN2Õ hybrid showed an intermediate susceptibility to PPV with slight sharka symptoms and were ELISA-DASI and RT-PCR positive. Whereas, ÔMontclarÕ peach and ÔEvricaÕ hybrid showed moderate resistance to PPV with slight sharka symptoms and were ELISA positive but RT-PCR negative. The results open new possibilities in the search for different sources of resistance to PPV within Prunus.

“…Consequently, the phenotyping method used was a key point for obtaining reliable results useful for QTL mapping, and a strong attention was put on this point in order to determine which parameters would be most appropriate. Phenotypic evaluations were carried out following the model of rootstock inoculation called "heavy test," used for PPV evaluation in Martínez-Gómez and Dicenta (2000b), Moustapha et al (2001), and Rubio et al (2003). Direct inoculation of cultivar or "standard test" has been more widely used (Dosba et al 1991;Audergon et al 1995;Pascal et al 2002;Decroocq et al 2005;Marandel et al 2009) as the latter is thought to be very similar to natural transmission by aphids (Labonne et al 1994) and allows the study of the virus movement towards the rootstock Ferri et al 2002;Decroocq et al 2005).…”

No valuable source of resistance to Plum pox virus (PPV), the causative agent of sharka disease, has been found in peach (Prunus persica), but polygenic resistance to PPV was described in Prunus davidiana clone P1908. Two previous studies using F 1 and F 2 populations derived from the nectarine cv. Summergrand and P. davidiana P1908 identified a total of six P. davidiana quantitative trait loci (QTLs) involved in PPV resistance (Marcus strain). In an effort to verify the QTL stability in a large progeny and to search for possible interactions of the genetic backgrounds, the current study evaluated the incidence of PPV infection in an F 1 population derived from the susceptible peach cv. Rubira and P. davidiana P1908 over three growth periods using an improved method of PPV phenotyping referred to as "heavy test." The phenotypic dataset was analyzed using similar methods as the previous studies and a newly developed simple-sequence-repeatbased P. davidiana map. Nine regions involved in differential symptom expression were identified among which six were common between studies. However, the level of resistance observed in the population was very low compared to the other studies, and the main QTL previously identified in linkage group 6 was not conserved, suggesting strong interaction of the genetic background of the susceptible parent with that of P. davidiana 1908. Consequently, this could be a limiting factor for developing resistant cultivars derived from P. davidiana P1908.

Members the Potyviridae family belong to a group of plant viruses that are causing devastating plant diseases with a significant impact on agronomy and economics. Plum pox virus (PPV), as a causative agent of sharka disease, is widely discussed. The understanding of the molecular biology of potyviruses including PPV and the function of individual proteins as products of genome expression are quite necessary for the proposal the new antiviral strategies. This review brings to view the members of Potyviridae family with respect to plum pox virus. The genome of potyviruses is discussed with respect to protein products of its expression and their function. Plum pox virus distribution, genome organization, transmission and biochemical changes in infected plants are introduced. In addition, techniques used in PPV detection are accentuated and discussed, especially with respect to new modern techniques of nucleic acids isolation, based on the nanotechnological approach. Finally, perspectives on the future of possibilities for nanotechnology application in PPV determination/identification are outlined.
