The technology described here represents a breakthrough development in that direction. Aimming to nos/plamid gene of four GMCs （RRS,Bt11, GA21, NK603）, by combining the multiple PCR with pyrosequencing, we developed a rapid assay for genotyping nos/plamid that relies on the identification of a single, type-specific ＇sentinel＇ base. The prototype assay was developed to recognize the four GMCs and was capable of recognizing simultaneously multiple GMCs infections. The studies established a rapid, reliable and cost-effective assay.
