“…Cacopsylla melanoneura and Cacopsylla picta spread the phytoplasma responsible for apple proliferation disease (Candidatus Phytoplasma mali) (Laviña et al, 2011). And finally, Cacopsylla pruni transmits the phytoplasma that causes European stone fruit yellows (Candidatus Phytoplasma prunorum) (Laviña et al, 2004).…”

Aim of study: In recent years an increase in pests and diseases associated with truffle plantations has been detected in Spain. The appearance of tumor malformations in trunks and branches of Quercus ilex L. must be highlighted. These bumps have expanded dramatically since the increase in the number and density of truffle plantations. This pathology is not only found in plantations, but also in forests, and in trees of all ages.Area of study: the eastern mountains and the truffle plantations of the Iberian Peninsula. Material and methods:Positive results were obtained by using two types of PCR: Real-Time PCR and nested-PCR. They were carried out with primers that amplified 16S ribosomal gene sequences that are common to all known phytoplasmas.Main result: The disease manifests itself as an irregular thickening in branches of any age and in the trunk that results in the woody tissue cracking open, forming wounds. The affected branches usually undergo necrosis and in case of affecting the trunk, the tree will eventually die. After an extensive literature review and several failed attempts to isolate fungal and bacterial species from these tumors and wounds, the disease-causing organism has been identified as a Candidatus Phytoplasma.Research highlights: The appearance of this disease may endanger the profitability of an a priori profitable crop. Due to the intrinsic characteristics of the organism, and knowing that no phytosanitary treatment is able to control phytoplasmas, future works should be directed towards identifying the transmitter in order to control the disease.

“…In fruit trees these diseases are transmitted by vectors and grafting. Vectors are sucking insects, mainly leafhoppers and psyllids, but until now only Cacopsylla pruni has been described as a vector of ESFY (Carraro et al, 2001;Jarausch et al, 2001b), having been identified in several regions of Spain (Laviña et al, 2004;Sabate et al, 2007).…”

The molecular characterization of the causal agent of diseases associated with several symptoms such as decline, yellowing, leaf roll and off-season growth in stone fruits made it possible to determine a common etiology, and the namé European stone fruit yellows´phytoplasma was proposed. Recently, the new taxonomical species description within the genus is 'Candidatus Phytoplasma prunorum'. A 2-yr survey was carried out in two different Prunus collections of the Centro de Investigación y Tecnología Agroalimentaria de Aragón (CITA) including European and Japanese plum genotypes of various species and several interspecific hybrids used as rootstocks. Both off-season growth in winter and decline were observed. In order to identify the phytoplasma suspected as a causal agent, two different PCR methods were applied to all inspected trees. The first method was a nested PCR with 16Sr X group-specific primers followed by RFLP analysis. The second method was a direct PCR with specific primers for 'Ca P. prunorum' (Eca1/Eca2). In the most symptomatic trees the presence of this phytoplasma was confirmed by at least one of the methods; negative results were obtained in asymptomatic trees. The nested PCR-RFLPs analysis was confirmed as a reliable method for routinary diagnosis rather than direct PCR.

Abstract:The European stone fruit yellows (ESFY) caused by 'Candidatus Phytoplasma prunorum' ('Ca. P. prunorum'), is a devastating, quarantine phytoplasma disease. This agent leads to serious damage in apricot and Japanese plum orchards, including decline of infected trees. The consequences are considerable economic losses in production. European plum and cherry are less susceptible to ESFY, although the 'Ca. P. prunorum' was also detected in these trees in several countries. ESFY seems to be limited to Europe and the neighboring regions (Asia Minor) as its incidence was reported from most of the southern and central European countries, Turkey, and Azerbaijan. 'Ca. P. prunorum' is transmitted by Cacopsylla pruni (Scopoli). The impact of 'Ca. P. prunorum' on stone fruit trees, as well as the methods of detection and identification and control management are reviewed.
