A robust absolute quantification protocol for potato virus Y based on reverse transcription-quantitative PCR
Year: 2025
Type: article
Abstract: Standardized protocols for absolute quantification of potato virus Y (PVY) from potato tissue is critical for host-virus dynamic studies. Here, we developed a standardized protocol using a cloned viral sequence as standards to detect and quantify PVY. Starting with total RNA, concentrated via column-based kit, this protocol is able to detect approximately 50 viral copies/reaction from multiple PVY strains. Validation of this protocol confirmed linearity across 8 orders of magnitude with high repeatability, reproducibility and statistical robustness across three independent runs. This protocol offers reliable PVY quantification to manage potato crop health and enables comparative studies with other viral systems.
