ABSTRACT
Nano-PCR is a potential tool for the early detection of plant viruses. In the current study, different concentrations of silver nanoparticles (20 nm) and magnesium oxide nanoparticles (50 nm) were included in the PCR mixture to improve the sensitivity of PCR for the detection of tomato leaf curl virus. The inclusion of nanoparticles in single or combination in PCR mixture has resulted in improvement of PCR sensitivity. Four-fold improvement was exhibited by the inclusion of 3 ng/µL silver nanoparticles, whereas the combination of silver and magnesium oxide nanoparticles (3 ng/µL and 200 ng/µL, respectively), resulted in a 4.5-fold improvement. The inclusion of 200 ng/µL of magnesium oxide nanoparticles in the PCR mixture exhibited a 7.6-fold increase in PCR sensitivity. Replacement of magnesium chloride with a combination of silver and magnesium oxide nanoparticles (3 ng/µL and 275 ng/µL, respectively) resulted in a 12-fold increase. A 13-fold improvement in PCR sensitivity was observed by the replacement of magnesium chloride in PCR buffer with 275 ng/µL of magnesium oxide nanoparticles. This could also produce detectable amplicon in PCR with a minimum of 25 cycles, resulting in a 26.5% reduction in the duration of PCR. This is the first report on the use of magnesium oxide nanoparticles in PCR for the early detection and better management of tomato leaf curl virus.
