“…The lack of grafting success in this study could be due to the negative effect of infection on graft compatibility. This fact was previously described in other Prunus rootstocks infected with PPV or ACLSV, showing a grafting success rate lower than 50% (Rubio et al 2009;Garc ıa-Ibarra et al 2012). Other factors affecting the accuracy of this method in controlled conditions include the behaviour of the viroid in the plant and its interaction with environmental conditions.…”

The apricot species is susceptible to infection by different viruses and viroids including the Hop stunt viroid (HSVd), widely distributed around the world and described as the causal agent associated with fruit degeneration disease in apricot. However, to date, there are no 'ad hoc' studies about the resistance or susceptibility of apricot cultivars to this viroid. In this study, we tested the resistance/susceptibility to HSVd of 26 Mediterranean and North American apricot cultivars in controlled greenhouse conditions. All apricot cultivars assayed were infected by HSVd, showing a different range of susceptibility. As no sources of resistance among the apricot cultivars evaluated have been detected yet, it is necessary to continue the search for such sources to be included in apricot breeding programmes. In addition, the high level of susceptibility found highlights the importance of identifying this viroid in routine tests performed by nurseries and plant protection services.

“…The use of genetic resistance sources potentially offers a durable solution for the control of viruses and viroids in Prunus species. Some natural sources of resistance to PPV and ACLSV have been described in different Prunus species (Rubio et al ., , ; García‐Ibarra et al ., ). However, for breeders and producers, the lack of widely reported sources of resistance to different viruses in the affected Prunus species is the most significant factor limiting the release of new resistant varieties (Rubio et al ., ).…”

The stone fruit genus Prunus, within the family Rosaceae, comprises more than 230 species, some of which have great importance or value as ornamental or fruit crops. Prunus are affected by numerous viruses and viroids linked to the vegetative propagation practices in many of the cultivated species. To date, 44 viruses and three viroids have been described in the 9 main cultivated Prunus species. Seven of these viruses and one viroid have been identified in Prunus hosts within the last 5 years. This work addresses recent advances and prospects in the study of viruses and viroids affecting Prunus species, mostly concerning the detection and characterisation of the agents involved, pathogenesis analysis and the search for new control tools. New sequencing technologies are quickly reshaping the way we can identify and characterise new plant viruses and isolates. Specific efforts aimed at virus identification or data mining of high-throughput sequencing data generated for plant genomics-oriented purposes can efficiently reveal the presence of known or novel viruses. These technologies have also been used to gain a deeper knowledge of the pathogenesis mechanisms at the gene and miRNA expression level that underlie the interactions between Prunus spp. and their main viruses and viroids. New biotechnological control tools include the transfer of resistance by grafting, the use of new sources of resistance and the development of gene silencing strategies using genetic transformation. In addition, the application of next generation sequencing and genome editing techniques will contribute to improving our knowledge of virus-host interactions and the mechanisms of resistance. This should be of great interest in the search to obtain new Prunus cultivars capable of dealing both with known viruses and viroids and with those that are yet to be discovered in the uncertain scenario of climate change. © 2017 Association of Applied Biologists Prunus virology M.

“…In the case of PPV, several sources of resistance have been identified and new resistant cultivars have been released. In the case of ACLSV, on the other hand, only two sources of resistance have been identified in the CEBAS-CSIC research center of Murcia: the traditional cultivar from Murcia 'Mauricio' and the French 'Bergeron' (García-Ibarra et al 2012).…”

Identification of quantitative trait loci (QTLs) linked to Apple chlorotic leaf spot virus (ACLSV) resistance in apricot

Apple chlorotic leaf spot virus (ACLSV), also known as apricot pseudo pox, "viruela" (in Spain) and "butteratura" (in Italy), has had a significant impact on the production of Prunus species, including apricot (P. armeniaca L.). Two apricot cultivars have recently been described as resistant to this virus: the traditional Spanish cultivar 'Mauricio' and the French cultivar 'Bergeron'. However, as far as we know, no work on the genetic control of the resistance to ACLSV has been published in any Prunus species. In this study, the transmission of resistance to ACLSV and the related Quantitative Trait Loci (QTLs) were analysed for three years in an F1 apricot progeny of 130 descendants derived from the cross 'Bergeron' (resistant to ACLSV) × 'Currot' (susceptible). The apricot descendants evaluated were classified as susceptible or resistant depending on the presence or absence of ACLSV evaluated through ELISA and RT-PCR. A non-parametric mapping method based on the Kruskal-Wallis (KW) test was used to score and identify linked QTLs. The 'Bergeron' cultivar showed a high capacity to transmit resistance to ACLSV, generating around 57% of the resistant descendants. Additionally, the results indicated an oligogenic control of ACLSV resistance in apricot, with significant QTLs in alternative years in linkage groups (LGs) 5 and 7 and in all years in LG2 andLG4.
