Objective To establish a loop–mediated isothermal amplification(LAMP) detection method for genetically modified (GM) Roundup Ready alfalfa events J101, which has not been authorized by the Min-istry of Agriculture of China. Methods The specific primer pairs based on the 3’junction sequence spanning the alfalfa DNA and inserted fragment of J101 were designed and then the LAMP detection system was established. The specificity and sensitivity were analyzed. Results The LAMP method was specific for GM alfalfa J101 detection, the limit of detection (LOD) were 16 pg J101 genomic DNA or 10 copies of alfalfa J101 haploid genomic DNA. Conclusion The established event-specific LAMP method for GM alfalfa J101 detection has high specificity and good sensitivity, and is suitable for quantification of J101 samples quickly and accurately.
