Abstract

In this study, a set of real-time PCR primers for the detection of aflatoxin in peanut was successfully designed according to the AFLR gene of Aspergillus niger. Upstream primer was 5'-AACCTGATGACGACTGATAT-3'; Downstream primer was 5'-AGCACCTTGAGAACGATAA-3'; The real-time PCR detection system established in this study had good specificity, and the sensitivity of DNA detection can reach 3×10-13 ng/ul. The correlation coefficient between the contents of aflatoxin in peanut samples and PCR Ct of Real-time was-0.718, and the correlation coefficient was significantly negative.
