“…This group is classified as 16SrX (Apple proliferation group) based on restriction fragment length polymorphism analysis of 16S rDNA sequences (Lee et al, 1995). This group X was further subdivided into subgroups A, B, C, D, E which correspond to the strain designations AP, ESFY, PD, SPAR and BWB respectively (Lee et al, 1995;Davis & Sinclair, 1998;Laimer Da Câmara Machado et al, 2001). Subsequent reports suggest that BWB should be represented as a single phytoplasma group separate from the AP group (Seemüller et al, 1998;Mäurer & Seemüller, 1996).…”

“…They reported that the phytoplasmas are eliminated in the above ground parts in winter and survive in the roots. Laimer Da Câmara Machado et al (2001) also reported that the appearance of symptoms in a tree may not be a reliable indicator of its phytoplasma status because they also found symptomless trees gave a positive ESFY phytoplasma signal. These reports suggest that it is not altogether surprising that we detected AlloY in a symptomless plant as it may have been in remission but with levels of phytoplasma detectable by PCR.…”

Allocasuarina muelleriana shrubs growing in natural sclerophyll roadside vegetation near Willalooka in the upper south-east of South Australia have a high incidence of a yellowing disorder in either all or part of the foliage, combined in some cases with a shortening and curling of the leaf-bearing stems. Samples from symptomatic and adjacent asymptomatic plants were tested for phytoplasmas by the polymerase chain reaction (PCR) assay. All but one asymptomatic plant were negative for phytoplasmas, whereas about half of the symptomatic plants were positive. Restriction fragment polymorphism analysis of PCR products indicated that the phytoplasma was related to the buckthorn witches'-broom (BWB) and apple proliferation (AP) groups of phytoplasmas, members of which have not been previously reported in Australia. Further evidence from the sequence of the 16S rRNA gene and the use of PCR primers specific to the AP and pear decline (PD) phytoplasmas confirmed the close relationship to the BWB and AP group phytoplasmas.

During the last 15 years, European stone fruit yellows (ESFY) has become a major concern in Austrian fruit production. Therefore, presence and temporal dynamics of its vector Cacopsylla pruni were investigated using a beating tray method and yellow sticky traps on Prunus armeniaca, Prunus domestica, Prunus spinosa and P. cerasifera nigra. Infection rates of C. pruni and Prunus spp. trees were assessed by direct, nested and real-time PCR. Movement of remigrants in a model apricot orchard was tracked by aid of a mark, release and recapture study. Insects were marked by fluorescent dyes. Movement of the marked insects and presence of naturally occurring insects were monitored by yellow sticky traps. In 2011, remigration of C. pruni to Prunus spp. started in calendar week 10 (8th of March) and in 2012, in calendar week 12 (18th of March). Remigrants were observed until calendar week 20 (middle of May), significant numbers of the springtime generation adults were present until week 26 (end of June). The phytoplasma was ascertained in 0-11.5% of the remigrants and in 0-3.44% of the springtime generation insects. About 9.8-63.3% of the apricot samples, 20-40% of the plum samples and single blackthorn samples were infected. The mark, release and recapture study proved a fast and frequent tree-to-tree movement of remigrated C. pruni adults. Insects easily covered distances from row to row or even farther (ca. 13 m) within 24 h after release and were present in a large part of the model orchard after 8 days (up to 24 m from release point).

“…(1994) determined the common aetiology of these diseases and proposed the single name ‘European stone fruit yellows’ (ESFY). Occurrences of ESFY have been reported in Spain (Sanchez Capucino & Forner, 1973), France (Desvignes & Cornaggia, 1982), Italy (Giunchedi et al ., 1978), Slovenia (Brzin et al ., 2001), Greece (Rumbos & Bosalidis, 1985), Romania (Ionica, 1985), Germany (Lederer & Seemüller, 1992), Czech Republic (Navratil et al ., 2001), England (Davies & Adams, 2000) and Austria (Laimer da Camara Machado et al ., 2001).…”

Role of wild Prunus species in the epidemiology of European stone fruit yellows

et al. 2002

View full text Add to dashboard Cite

Several uncultivated trees of the species Prunus spinosa , P. cerasifera and P. domestica , sampled both adjacent to European stone fruit yellows (ESFY)-infected orchards and in isolation from cultivated stone fruit plants, were found to be infected by ESFY phytoplasma. These species were also colonized by Cacopsylla pruni , vector of the ESFY agent. In contrast, uncultivated species of Prunus avium , P. cerasus and P. mahaleb hosted neither the pathogen nor the vector. Insect-and graft-transmission trials of ESFY phytoplasma conducted under controlled conditions confirmed the data obtained in the field. The role played by the wild Prunus species is discussed and appears to be fundamental in the epidemic cycle of the disease.
