dc.description.abstractGrapevine Roditis leaf discoloration-associated virus (GRLDaV) is a type of virus that infects grapevines. This research aimed to determine the prevalence of GRLDaV in Turkey vineyards and investigate the genetic diversity and population structure of the selected viral isolates from Turkey compared to isolates from other countries. In this study, 800 shoot samples from Turkey vineyards were collected in late spring and autumn from different regions. The samples were analysed by RT-PCR targeting the partial RNaseH-like gene region of the virus genome. The overall prevalence of GRLDaV was 8.1% among the samples. Phylogenetic analysis of the GRLDaV genome showed that the GRLDaV isolates were clustered into two major lineages. The nucleotide diversity (pi) value of Group I, including only Mediterranean isolates, was lower than Group II, suggesting little variation among isolates. Even though pi values were low among the geographical regions in Turkey, the region with the highest nucleotide diversity was the Aegean population, followed by the Eastern and Mediterranean populations. Comparison between nonsynonymous and synonymous substitutions showed that negative selection acts on synonymous amino acids. Along with neutrality tests and gene flow analyses, it was emphasized that genetic drift played an important role in shaping the GRLDaV populations. This study provides important information on the prevalence and genetic diversity of GRLDaV in Turkey vineyards. The findings will help to develop better strategies to manage and control this virus, which can cause significant economic losses in grape industries.
