Abstract Two singleplex TaqMan methods were developed for the detection of potato targets: one for the detection of the tpinII terminator, which is an emerging terminator used in GM constructs, and one for the detection of the endogenous StLS gene of potato. Performance criteria such as specificity and sensitivity were successfully tested for the two methods, taking into account the recommendations of international guidelines. The presence of the StLS target was checked in 16 potato cultivars. The StLS target is present at low copy number and can be used for quantitation purposes, as demonstrated on transgenic potatoes in this paper. The StLS target is an excellent candidate to replace the presently recommended endogenous target based on the UGP gene, which shows several disadvantages due to its high copy number and lack of specificity. The research also indicates that DNA can easily be extracted from different parts of potato tubers with a classical CTAB method.
