Plum pox virus (PPV) is the causal agent of Sharka disease. Since its discovery, Sharka has been considered as a calamity in plum orchards. PPV is present worldwide in many Prunus species, causing great economic losses. In highly susceptible plum varieties, such as Požegača, PPV causes a premature fruit drop and reduces fruit quality, which leads to total yield loss. Eight PPV strains (PPV-M, P...

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 qu...

Plum pox or sharka, a viral disease caused by Plum pox virus (PPV), severely affects the production of Prunus species in Europe. The first evidence of sharka was reported in Iran in 2000 . Due to the economic impact of this disease on crop production, recent advances in the term of  biology, epidemiology, and disease management are provided in this paper to assure awareness among growers and pr...

Research to date indicates that post-transcriptional gene silencing (PTGS) is an effective strategy for the development of stable high-level resistance to Plum pox virus in plum. Field tests in Poland, Romania, and Spain show that after 5–6 years of natural aphid vectored inoculation, trees of the PTGS clone C5 remain virus-free. The effectiveness of transgene-based PTGS for imparting potyvirus...

Genetic resistance to Plum pox virus (PPV) is the most viable alternative for long-term control of sharka disease. In addition to the classical approaches to producing resistant germplasm and cultivars, genetic transformation offers a promising genetic approach to resistance. We show, using the example of C5 plum, that genetically engineered resistance can provide durable, stable and high level...

Plum pox, an invasive disease recently identified in Pennsylvania stone fruit orchards, is caused by the aphid-transmitted Plum pox virus (genus Potyvirus, family Potyviridae, PPV). To identify potential vectors, we described the aphid species communities and the seasonal dynamics of the dominant aphid species within Pennsylvania peach orchards. Aphids were trapped weekly in 2002 and 2003 from ...

Polák J., Komínek P. (2016): Investigation on the incidence of Plum pox virus in fruit nurseries of the Czech Republic. Plant Protect. Sci., 52: 158–163. Nine different visual evaluations of Plum pox virus (PPV) presence were carried out in four nurseries during 2012–2015. Results of visual evaluation were verified by ELISA. The presence of PPV was confirmed by ELISA in all the trees showing PP...

The susceptibility of peach GF 305 seedlings and herbaceous plants to five plum pox virus (PPV) isolates from orchards of western Slovakia was investigated. PPV was isolated from diseased plum, apricot and peach trees, and transmitted by chip-budding to peach GF 305. The herbaceous plants were infected by mechanical inoculation. The transmission was analysed by symptomatology and double sandwic...

ABSTRACT The dynamics of virus interference between two isolates of Plum pox virus (PPV) belonging to the main PPV types, D and M, were analyzed in Japanese plum (Prunus salicina) by challenge inoculations. To assess the consequences of a PPV-M infection on plum already infected with PPV-D, and vice versa (predominance of one of the strains, recombination, synergism, symptoms aggravation, and s...
