“…In a survey study conducted in Trakya region (Turkey), a total of 260 wheat samples were tested against BYDV in 2003. The incidence of infection levels were 25% for BYDV-MAV, 22.3% for BYDV-PAV and 8.5% were CYDV-RPV (Köklü, 2004). Likewise, in another study conducted in Edirne, Kırklareli, and Tekirdağ province reported that 63 out of 90 leaf samples (corresponding 70%) were infected with BYDV-PAV by ELISA in 2001(Ilbagi et al, 2008.…”

“…However, variation in susceptibility has been found among cultivars [ 10 – 13 ], and recently two Hungarian winter wheat cultivars were found to display partial resistance to WDV [ 14 ]. WDV disease outbreaks may occur periodically and cause yield losses in most of Europe and in parts of Africa and Asia [ 14 , 15 ]. Recently, WDV has also been detected in Syria [ 16 ] and in Iran [ 17 ].…”

“…Most Aegilops spread to the west except the species carrying the D-genome which spread into Eastern Asia [ 36 , 51 ]. The distribution of wild relatives in the Fertile Crescent partly overlaps with regions where WDV has been detected in Turkey, Syria and Iran [ 15 – 17 ].…”

Variation in Susceptibility to Wheat dwarf virus among Wild and Domesticated Wheat

et al. 2015

We investigated the variation in plant response in host-pathogen interactions between wild (Aegilops spp., Triticum spp.) and domesticated wheat (Triticum spp.) and Wheat dwarf virus (WDV). The distribution of WDV and its wild host species overlaps in Western Asia in the Fertile Crescent, suggesting a coevolutionary relationship. Bread wheat originates from a natural hybridization between wild emmer wheat (carrying the A and B genomes) and the wild D genome donor Aegilops tauschii, followed by polyploidization and domestication. We studied whether the strong selection during these evolutionary processes, leading to genetic bottlenecks, may have resulted in a loss of resistance in domesticated wheat. In addition, we investigated whether putative fluctuations in intensity of selection imposed on the host-pathogen interactions have resulted in a variation in susceptibility to WDV. To test our hypotheses we evaluated eighteen wild and domesticated wheat taxa, directly or indirectly involved in wheat evolution, for traits associated with WDV disease such as leaf chlorosis, different growth traits and WDV content. The plants were exposed to viruliferous leafhoppers (Psammotettix alienus) in a greenhouse trial and evaluated at two time points. We found three different plant response patterns: i) continuous reduction in growth over time, ii) weak response at an early stage of plant development but a much stronger response at a later stage, and iii) remission of symptoms over time. Variation in susceptibility may be explained by differences in the intensity of natural selection, shaping the coevolutionary interaction between WDV and the wild relatives. However, genetic bottlenecks during wheat evolution have not had a strong impact on WDV resistance. Further, this study indicates that the variation in susceptibility may be associated with the genome type and that the ancestor Ae. tauschii may be useful as genetic resource for the improvement of WDV resistance in wheat.

“…According to molecular tests, BYDV-MAV infection was not found in Mardin province, in correlation with those surveyed in the Eastern Anatolia Region (10 provinces) with 900 wheat samples by Usta et al (2020) and in Samsun province with 184 samples Toksöz ve Yılmaz (2016). However, the occurrence of BYDV-MAV has been confirmed at varying proportions (25%, 2.14%, and 2%) in surveys conducted by Köklü (2004), İlbağı (2017), Erkan and Yılmaz (2009) in Turkey.…”

Wheat (Triticum aestivum L.) is a natural host of many viruses. Yellow dwarf viruses belonging to the Luteoviridae family are important virus species that cause economic loss by restricting wheat production worldwide. Surveys were conducted in 2017 to determine Yellow dwarf viruses (BYDV-PAV, BYDV-MAV, BYDV-SGV, BYDV-RMV, and CYDV-RPV) and their infection rates in wheat production areas in Mardin province. 400 fresh leaf samples collected were tested by Multiplex reverse transcription-polymerase chain reaction (m-RT-PCR). The overall infection rate was found to be 3%. BYDV-PAV has been identified as the most widespread virus with a 2.5% presence rate. It was found out that BYDV-SGV, CYDV-RPV, and BYDV-RMV infections were lower, with rates of 1.75%, 0.5% and 0.25% respectively. In the current study, double infections were detected in 8 samples. The overall infection rate of the detected viruses (BYDV-PAV, BYDV-SGV, CYDV-RPV, BYDV-RMV) was found to be lower than the records reported in previous similar studies. No BYDV-MAV infection was found in any of the wheat samples tested. The cDNA of the coat protein (CP) gene of a BYDV-PAV isolate randomly selected from virus-positive samples was cloned, bidirectionally sequenced, and the phylogenetic relationship revealed. According to the phylogenetic analysis with 19 different isolates in the NCBI database of BYDV-PAV Mardin isolate, it showed the highest genetic similarity by 95.52% with the Germany isolate (KY634926) while the lowest similarity rate was 89.22% with the Germany and Pakistan isolates (KY634886 and JQ811489). The presence of BYDV-PAV, BYDV-SGV, CYDV-RPV, and BYDV-RMV were reported for the first time with this survey study conducted in Mardin.
