Simultaneous Detection of Grapevine Viruses via Multiplex Reverse Transcription Polymerase Chain Reaction: An Academic Approach

Abstract

AbstractGrapevine viruses pose a significant threat to the viticulture industry, resulting in reduced grape yield, poor fruit quality, and economic loss. Accurate and timely detection of multiple viruses are essential for effective disease management and the implementation of appropriate control measures. The aim of this study was to assess the presence of grapevine fanleaf virus (GFLV), grapevine fleck virus (GFkV), grapevine leafroll-associated virus‑1 (GLRaV-1), arabis mosaic virus (ArMV), and grapevine virus A (GVA) in 320 plant samples collected from the Aegean region of Turkey using the powerful technique of multiplex reverse transcription-polymerase chain reaction (RT-PCR). Through comprehensive analysis, 119 of the 320 infected samples were identified using PCR. The distribution of the detected viruses revealed the presence of 28 GFLV, 31 GLRaV‑1, 12 GFkV, 21 GVA, and 27 ArMV. By comprehensively analyzing the samples, the researchers were able to simultaneously detect and identify the target viruses using a single, cost-effective assay. These results reveal the prevalence and distribution of these viruses in the Aegean region, providing valuable insights into the viral landscape of grapevines in this important viticultural area. The high detection rates of these viruses highlight the urgent need for improved disease management strategies to safeguard vine health and productivity.
