Abstract
Exogenous fragment sequence and flanking sequence between exogenous fragment and recombinant chromosome of transgenic wheat B72-8-11b were successfully acquired through PCR amplification with cross-matched primers from exogenous genes. Newly acquired exogenous fragment covered the full-length sequence of transformed genes such as transformed plasmid and corresponding functional genes including marker uidA, promoter ubiquitin, lacZ, 1Dx5, and part of sequence of the wheat genome. A specific PCR detection method for transgenic wheat B72-8-11b strain was established on the basis of primers designed according to flanking sequence. The designed primers revealed specific amplification of 132 bp product of transgenic wheat B72-8-11b strain. This method is characteristics of high specificity, high reproducibility, rapid identification, and excellent accuracy for the identification of transgenic wheat B72-8-11b strain.
