“…This diversity is partially structured by geography in Turkey, which probably represents the PPV‐T centre of origin. Except for Albania, where a single PPV‐T isolate was detected among the highly prevalent PPV‐M and less represented PPV‐D and PPV‐Rec isolates (Palmisano et al ., ), PPV‐T has not been identified in any of the other neighbouring countries such as Greece (Varveri, ), Bulgaria (Kamenova et al ., ), Romania (Zagrai et al ., ), Croatia (Kajic et al ., ) and Serbia (Jevremović & Paunović, ). In contrast, in the Balkan/Thrace region of Turkey, and central Anatolia territories such as Ankara, Kayseri, Konya and Kırıkkale, PPV‐T isolates account for most cases of infection (Ulubaş Serçe et al ., ; Gürcan & Ceylan, ).…”

Genetic diversity and molecular epidemiology of the T strain of Plum pox virus

Very limited information is available on the origin, diversity and evolution of Plum pox virus (PPV) 'Turkey' (T) strain. Phylogenetic analyses based on partial sequences of 421 isolates and complete genome sequences of 57 isolates, representing the geographical distribution of PPV-T in Turkey, revealed the existence of several monophyletic and, in some cases, geographically limited groups within the PPV-T strain (Ankara-Konya1-Kayseri, Ankara-Balkan, Istanbul, Konya2 and Balkan). PPV-T diversity (0.018%) was found to be greater than that of PPV strains D and Rec but lower than that of the M strain when including the newly described and divergent M-Istanbul isolates, suggesting a long evolutionary history for PPV-T. The European part of Turkey in the Balkans, close to Bulgaria where PPV was identified for the first time, appears as a likely centre of origin for PPV-T isolates. The colonization of various parts of Turkey by diverse isolates from that region, followed by secondary local spread, is the most likely scenario for the diffusion of PPV-T in Turkey.

“…More recently a minor recombination hosted by PPV-Rec isolates, spanning a genomic segment from nucleotide 940-1838 was also reported (Chirkov, Ivanov, et al, 2018b). In the last two decades, the isolates of PPV-Rec strain were reported in European countries: in Slovakia, Albania, Bulgaria, Hungary, Czech Republic, Germany (Gadiou et al, 2008;Glasa et al, 2002Glasa et al, , 2004Kamenova & Borisova, 2019;Salamon & Palkovics, 2002); former Yugoslavia (Cervera et al, 1993;Glasa et al, 2005;Jevremovic & Paunovic, 2014;Kajic et al, 2008;Matic et al, 2006), Italy (Myrta et al, 2005), France (Svanella-Dumas et al, 2015), and in other countries: Turkey (Candresse et al, 2007), Pakistan (Kollerova et al, 2006), Canada (Thompson et al, 2009) and in Russia (Chirkov, Ivanov, et al, 2018b).…”

Genetic diversity and a long evolutionary history of plum pox virus strain rec in Turkey

et al. 2021

Plum pox virus strain Recombinant (PPV-Rec) is hypothetically considered as homologous recombinant between strains PPV-M and PPV-D. The nucleotide position 8450 up to end of genome is considered to come from PPV-M, and the remaining major genomic part is PPV-D-derived. It is regarded as third major PPV strain due to its wide distribution and prevalence in Europe. However, among over a thousand PPV isolates genetically identified in Turkey, only 10 of them (<1%) were characterized as PPV-Rec. The nearly complete genome of eight of the PPV-Rec isolates from European part of Turkey were obtained and analyzed together with PPV-Rec isolates of other countries. All major genomic features were conserved among Turkish PPV-Rec isolates. The genetic diversity of PPV-Rec isolates in Turkey (n = 8, 0.015 ± 0.001%) was found to be comparable to that observed for the isolates from eight countries (n = 10, 0.014 ± 0.001%). Particularly, genetic diversity of the minor recombinant fragment for Turkish PPV-Rec isolates was apparently higher (0.016 ± 0.001%) than the value for the 10 isolates from eight countries (0.011 ± 0.001%). The high genetic diversity was also demonstrated by high phylogenetic variation in Turkish isolates, indicating a long evolutionary history of PPV-Rec isolates in Turkey. After including Turkish isolates in the recombination analysis, the major putative recombination event of PPV-Rec isolates with a breakpoint around position 8450 was identified again, however the other recently reported putative recombination events were not supported in this study by the algorithms implemented in the RDP software.

“…PPV was detected for the first time in Bulgaria in 1917 (Atanasoff, 1932), and it is currently considered a typical plant pathogen for the Balkan peninsula, but it is also an important common or quarantine pathogen worldwide (Melika & Krizbai, 2021). According to Jevremović and Paunović (2014), PPV infection has reached 80% in some southern localities in Serbia. As some of the autochthonous and widely-grown plum cultivars (such as Požegača) are very susceptible to PPV, plum production in Serbia has sustained a considerable decline.…”

Plum pox virus infection level in Prunus species growing along roadsides or in backyards in Vojvodina province

et al. 2021

The present study was conducted on 106 leaf samples of Prunus species (44 plum, 47 myrobalan plum, 10 apricot, 3 peach, 1 blackthorn, and 1 sour cherry) collected from the Vojvodina province of Serbia and assessed for the presence of Plum pox virus (PPV) with the aim of establishing whether trees growing along roadsides and in backyards could be sources of PPV infection in commercial orchards. Analyses confirmed PPV infection in 68.2%, 38.6%, and 20% of plum, myrobalan plum and apricot samples, respectively. The infection level varied considerably across locations, with 80% noted in Uljma, followed by 69% in Sremska Kamenica, 60% in Becej, 50% in Temerin, 50% in Senta, 40% in Petrovaradin, 31% in Novi Sad, 30% in Susek, and 20% in Subotica. As no difference in infection rates was noted between young and older plum trees, the infections seemed to have occurred in their early life stage. Trees growing along roadsides were infected to a higher extent (89.6%) than those in backyards (66.6%). In some cases, symptomless trees were also proven to be PPV positive, indicating that they are a potentially important source of further virus infections. Due to the widespread presence of the virus, tolerant or hypersensitive cultivars are recommended for planting new orchards.
