Development of a Real-Time RT-PCR for the Universal Detection of LChV1 and Study of the Seasonal Fluctuation of the Viral Titer in Sweet Cherry Cultivars

Little cherry virus 1 (LChV1) is a sweet cherry pathogen which has lately been reported in other Prunus spp. LChV1 variability makes reliable detection a challenging undertaking. The objective of this work was to develop a rapid, sensitive, and reliable one-tube, real-time reverse-transcription poly...

520 |a Little cherry virus 1 (LChV1) is a sweet cherry pathogen which has lately been reported in other Prunus spp. LChV1 variability makes reliable detection a challenging undertaking. The objective of this work was to develop a rapid, sensitive, and reliable one-tube, real-time reverse-transcription polymerase chain reaction (RT-PCR) for the detection and quantification of LChV1. Primers and a TaqMan probe were designed, using conserved regions of the capsid protein gene. Detection range was evaluated using several divergent viral isolates. The amplification efficiency of the method was estimated at 96.7%, whereas the detection limit was about 100 RNA copies. The protocol was applied in the study of virus fluctuation within leaves and phloem tissue throughout the year and the best periods to test and plant tissues to sample were determined. Comparative analysis of this method with a previously published nested RT-PCR revealed the higher analytical and diagnostic sensitivity of the new test, making it a reliable tool that can be used in routine testing and certification programs
