Abstract:
The present invention relates to a method for detecting and distinguishing a beet curly top virus, a beet severe curly top virus, and a beet mild curly top virus which are viruses of the genus curtovirus using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). More specifically, the present invention relates to a method for detecting and distinguishing each of the viruses by confirming pieces after treating Dra I, which is a restriction enzyme, on a byproduct that is amplified using a primer set for PCR that can amplify all of the three viruses. By means of the method according to the present invention, three species of the curtovirus can be effectively diagnosed and distinguished within a short period of time without high-priced technical equipment such as sequence analysis equipment. The species are not reported to have occurred in Korea but the viruses often occur in major agricultural importers including North America. Accordingly, the curtovirus that can severely damage farms is rapidly and accurately detected in a preemptive plant quarantine step so that a huge economical loss can be remarkably reduced.
Abstract:
PURPOSE: A primer composition for loop-mediated isothermal amplification reaction for detecting tomato yellow leaf curl virus is provided to quickly diagnose the virus using high concentration SYBR Green I under natural light with naked eye. CONSTITUTION: A primer set for loop-mediated isothermal amplification reaction for detecting tomato yellow leaf curl virus has sequence numbers 1-4. The primer set has sequence numbers 11-14. The virus is selected from the group consisting of TYLCV Jordan1 mutant strains, Jordan3 mutant strains, Israel mutant strains, Spain mutant strains, USA mutant strains, and Korea mutant strains. A primer composition for loop-mediated isothermal amplification reaction for detecting the virus contains the primer set, DNA polymerase, dNTPs, and a reaction buffer.

Abstract:
The present invention relates to a method for detecting and distinguishing a host-specific strain of a Tomato yellow leaf curl virus (TYLCV) using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). More specifically, the present invention relates to a method for detecting and distinguishing Korea, Israel, Spain, USA, Jordan 1, Jordan 2, and Jordan 3 which are seven strains of the Tomato yellow leaf curl virus (TYLCV) from an amplified product, which is amplified using a primer set for PCR for detecting a host-specific strain of a TYLCV, using Dde I, Fau I, or Bss SI which is a restriction enzyme. By means of the method according to the present invention, the infection of the TYLCV and the strain can be effectively confirmed within a short period of time without high-priced technical equipment such as sequence analysis equipment. Accordingly, the spread of the TYLCV is domestically prevented, and the inflow of domestically non-occurred strains can be prevented in a plant quarantine step, so that a huge economical loss can be remarkably reduced.
