International audienceInformation concerning the evaluation of apricot resistance to sharka (plum pox potyvirus) has in many cases been published in journals of limited circulation. In an attempt to assess the actual status of this resistance, a global review has been made, including 222 cultivars, 175 of which can be considered as susceptible, 27 as resistant and 20 as cultivars of uncertain classification. Such a doubtful classification could be due to differences in evaluation methods, the isolates used, or to the authenticity of the plant material. The results seem to indicate that the main origin of resistance to sharka could be North American cultivars, although other resistant sources have been found in Central Europe.Comportement des cultivars d'abricotier (Prunus armenica L.) à la sharka (plum pox potyvirus) : une revue. Les informations concernant l'évaluation du comportement de l'abricotier à la sharka sont fréquemment publiées dans des journaux à faible audience. La présente revue se propose de synthétiser ces informations dispersées : 222 cultivars sont pris en compte, 175 d'entre eux pouvant être considérés comme sensibles, 27 comme résistants et 20 pour lesquels la classification est incertaine. Cette classification douteuse peut être due à des différences dans les méthodes d'évaluation, aux isolats utilisés ou à l'authenticité du matériel végétal. Les résultats semblent indiquer que la principale source de résistance à la sharka aurait pour origine les cultivars nord-américains bien que d'autres sources de résistance ont été trouvées en Europe centrale

Sharka disease, caused by Plum pox virus (PPV), is the most important viral disease affecting Prunus species. A major PPV resistance locus (PPVres) has been mapped to the upper part of apricot (Prunus armeniaca) linkage group 1. In this study, a physical map of the PPVres locus in the PPV-resistant cultivar 'Goldrich' was constructed. Bacterial artificial chromosome (BAC) clones belonging to the resistant haplotype contig were sequenced using 454/GS-FLX Titanium technology. Concurrently, the whole genome of seven apricot varieties (three PPV-resistant and four PPV-susceptible) and two PPV-susceptible apricot relatives (P. sibirica var. davidiana and P. mume) were obtained using the Illumina-HiSeq2000 platform. Single nucleotide polymorphisms (SNPs) within the mapped interval, recorded from alignments against the peach genome, allowed us to narrow down the PPVres locus to a region of ∼196 kb. Searches for polymorphisms linked in coupling with the resistance led to the identification of 68 variants within 23 predicted transcripts according to peach genome annotation. Candidate resistance genes were ranked combining data from variant calling and predicted functions inferred from sequence homology. Together, the results suggest that members of a cluster of meprin and TRAF-C homology domain (MATHd)-containing proteins are the most likely candidate genes for PPV resistance in apricot. Interestingly, MATHd proteins are hypothesized to control long-distance movement (LDM) of potyviruses in Arabidopsis, and restriction for LDM is also a major component of PPV resistance in apricot. Although the PPV resistance gene(s) remains to be unambiguously identified, these results pave the way to the determination of the underlying mechanism and to the development of more accurate breeding strategies.
