Sensitivity test of UMPS gene using serial dilutions of genomic DNA from fresh tobaccoleave samples. (a) LAMP method through direct visual detection with SYBR Green I; (b) LAMP method on 2% agarose gel electrophoresis analysis. Lane 1: NTC; lanes 2–9: 120, 60, 30, 15, 7.5, 3.75, 1.88, and 0.94 ng per reaction, respectively; lane M: Trans 2K DNA marker. (c) qPCR method. For standard curve, a serial dilution of DNA samples (120, 60, 30, 15, 7.5, 3.75, 1.88, 0.94, 0.47, 0.24, 0.12, and 0.06 ng) was used. The result was developed after considering 3 independent experiments with three replications.
