The application belongs to the technical field of
gene detection, and particularly relates to
specific primers, a
Taqman probe and application of a
bacillus velezensis HMB26553 strain. The
specific primers and the probe sequence of the
bacillus velezensis HMB26553 strain are respectively SEQ ID NO. 1, SEQ ID NO. 2 and SEQ ID NO. 3. The primers can amplify a single unique target fragment from the
bacillus velezensis HMB26553 strain, and realize
specific detection of the bacillus velezensis HMB26553 strain. The primers have the characteristics of high specificity, high detection efficiency, low
false positive rate, long preservation time and the like. By using the primers and through real-time quantitative PCR technology, the
population quantity of the bacillus velezensis HMB26553 strain in the
rhizosphere of cotton can be quickly quantified, and the primers have the advantages of high
throughput, rapidness and accuracy.
