Embodiment 1
[0026] A molecular marker primer for distinguishing pomfret ovata and pomfret brinneri and its identification method:
[0027] 1) Select 5 individuals of Pomfret Oval and Pompano Brycei species collected from the coastal waters of Sanya, Hainan to form a sample group, and extract the DNA of the two sample groups respectively;
[0028] 2) using the DNA extracted in step 1) as a template, and amplifying through the PCR reaction system with primer CSF and primer CSR respectively;
[0029] The composition of described PCR reaction system is:
[0030] Add in order to the 0.2ml centrifuge tube:
[0031]
[0032] The PCR amplification program was pre-denaturation at 94°C for 2 min, (denaturation at 94°C for 15 sec, annealing at 50°C for 15 sec, extension at 72°C for 15 sec) x 38 cycles, extension at 72°C for 3 min, and storage at 4°C for long-term storage.
[0033] 3) Purify and sequence the PCR products, and compare the sequencing results of the two populations to identify thei...
