dc.description.abstractGrapevine leafroll-associated virus-1 (GLRaV-1), one of the causal agents of Grapevine leafroll disease (GLRD), is one of the most important viral diseases of grapevine worldwide. In this study, the prevalence of GLRaV-1, genetic variation and recombination events among GLRaV-1 isolates in Turkey were investigated. Initially, 197 grapevine samples from different provinces of the country were serologically tested. Of the total samples, 109 (55.32%) were identified as GLRaV-1 infected. Subsequently, 9 samples representing different geographic distribution were selected for further sequence analysis of the heat-shock protein 70 homolog (HSP70h), open reading frame 9 (p24), coat protein (CP) and coat protein duplicate 2 (CPd2). Among the four gene regions, CPd2 was found the most divergent region while HSP70h gene exhibited the lowest genetic diversity. The phylogenetic analysis of four genomic regions including GenBank records clustered all variants in two major groups and grouped Turkish isolates mostly together. However, the isolate clusters were not correlated to their geographic origin. Furthermore, several putative recombination events were detected with trace to moderate evidence support of algorithms implemented in Recombination Detection Program (RDP). Taken together, the results provide a better understanding on genetic variation of Turkish GLRaV-1 isolates in the country and worldwide and can help to improve sanitation of propagated material programs for the grape growers.
