Validation of RT-PCR High Resolution Melting as a detection method of Tombusvirus
F. OCHOA (1)Y. Carrillo Tarazona (1), (1) Oklahoma State University, U.S.A.<br>Plant waterborne viruses, such as some in the genus Tombusvirus, spread as colloids in water and also by mechanical transmission. Broad detection and simultaneous species discrimination of viruses in this genus is needed for testing field samples. RT-PCR coupled to High Resolution Melting (HRM) has been used for different forensic applications and allows species differentiation as well as SNP detection. Tombusvirus. complete genomic sequences retrieved from the NCBI-Genbank were used to design primers for broad detection using this method. Ten different virus species, Carnation italian ringspot virus (CIRV), Cucumber necrosis virus (CNV), Cymbidium ringspot virus (CymRSV), Grapevine Algerian latent virus (GALV), Neckar river virus (NRV), Pelargonium leaf curl virus (PLCV), Pelargonium necrotic spot virus (PNSV), Petunia asteroid mosaic virus (PetAMV), Tomato bushy stunt virus (TBSV) and Pelargonium line pattern virus (PLPV) were sourced by the DSMZ (Germany) and AGDIA (USA) and used for nucleic acid extraction. All viruses tested positive to broad detection endpoint RT-PCR with primers designed to react when coupled to HRM. Melting curve predictions calculated by uMeltSM algorithms were compared with data obtained using three DNA dyes (SYBR® Green, SYTO®9 and LCGreen®). Results with LCGreen® are closer to the predicted data calculated by uMeltSM when the amplicon size is between 50-200bp.
