| Abstract: | The purpose of the study is to develop an loop-mediated isothermal amplification（LAMP）technique for the detection of genetically modified papaya line 55-1. Five sets of LAMP primers were designed according to the specific sequences of genetically modified papaya line 55-1， and primers with high amplification efficiency were screened. The LAMP reaction temperature and reaction system of the set of primers were optimized， and the specificity， sensitivity and stability of the LAMP method were determined. The results indicated that the set of LAMP primers could detect genetically modified papaya line 55 -1 specifically and stably， with a sensitivity of 0.05% and a detection result within 30 min. Therefore，the LAMP method can effectively detect the genetically modified papaya line 55-1， which not only simplifies the detection steps， but also shortens the detection time， and provides technical support for the rapid detection of transgenic papaya. |
