“…The PPV-D resistance in 'Henderson confirms the results of Audergon et al (1994). However, this cultivar has been described as susceptible to PPV-M isolates (Balan and Stoian, 1995) which are more aggressive in apricot than PPV-D isolates (Candresse et al, 1994).…”

The resistance to a Dideron isolate of Plum pox virus, which causes sharka disease, of four apricot (Prunus armeniaca L.) cultivars from North America (`Harlayne', `Henderson', `Sunglo', and `Veecot') and a Greek cultivar Lito (a cross of American cultivar Stark Early Orange × Greek cultivar Precoce Tirynthos) was evaluated. `Stark Early Orange' and `Canino', previously rated as resistant and susceptible respectively, were included as controls. Resistance, herein, was defined as inability to infect plants by graft-inoculation and negative assays by enzyme-linked immunosorbent assay. Cultivars found to be resistant were: `Harlayne', `Henderson', `Sunglo', `Lito', and `Stark Early Orange'. Cultivars Veecot and Canino were susceptible.

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

“…Goldrich, Stella and Stark Early Orange (SEO). In such resistant cultivars, symptoms on leaves or fruits have not been observed, virus particles are not detected except in two contradictory reports which could be due to differences in inoculation or evaluation methods, the isolates used or the authenticity and sanitary state of the plant material (AUDERGON et al 1994;BALAN & STOIAN 1995;POLÁK et al 1995;MARTINEZ-GOMEZ et al 2000;FUCHS et al 2001). F1 and F2 progenies were developed from crosses with several apricot genitors that carry different types of resistance.…”

Plum pox virus (PPV), the causing agent of the sharka disease, belongs to the genus Potyvirus that contains the largest number of virus species infecting plants. The virus genome has been extensively characterised and sequenced. However, few data are available on its interactions with the host plant, Prunus. In this study, we are focusing on the cloning and characterisation of any candidate genes involved in the expression of the resistance/susceptibility trait and any polymorphic genes putatively involved in the trait variation. In order to clone candidate genes, two main approaches are currently developed: the homology cloning of genes presumed to affect the resistance/susceptibility trait and the differential screening of cDNA pools corresponding to infected and non-infected plant material. The second approach is based on the transcript imaging of the host plant response to PPV infection. Previously, it has been shown that infection by a potyvirus is associated with specific changes in host gene expression, mainly down-regulation, while the expression of some genes remained unchanged. Thereby, in the differential display approach combined to further characterisation of candidate gene expression, we aim to monitor host gene expression in response to the virus and to describe a highly regulated interaction between the Prunus host plant and the infecting Plum pox virus.
