Abstract
Rose yellow vein virus (RYVV) is a viral agent that has been identified in roses in recent years and is known to exist in a very limited area in the world. However, in studies conducted in our country, the presence of the agent has been detected in different regions and provinces. Since direct chemical control of viral diseases is not possible as in other biotic diseases, molecular characterization of the agent forms the basis for possible resistance or gene silencing studies to be conducted in the coming years. Thus, 44 RYVV isolates previously identified in our country were used for full genome studies. In full genome studies, overlapping PCR method was used with 7 different species-specific primer pairs. The full genomes of 3 of these isolates were obtained. The full genomes of the other isolates could not be obtained. It was determined that the genome size of the 3 RYVV isolates whose full genomes were obtained was 9314 nucleotides. It was determined that the only RYVV isolate found in the GenBank and the Türkiye isolates also showed a high level of nucleotide sequence similarity. However, the fact that the entire genome of the other isolates could not be obtained and the ones obtained were amplified with primer pairs designed according to the single isolate in the GenBank database may be due to the presence of different strains of RYVV isolates. For this reason, it is thought that next-generation sequencing studies should be prioritized to obtain complete genome information in future studies.
