Transgene transcripts normalized relative expression levels measured by delta-delta Cq method and Pffafl correction equation. The cry1A.105 and cry2Ab2 transgenes were quantified in single versus stacked transgenic maize events grown under controlled conditions at V3 stage. Samples are means of three pools, each derived from ten different plants. ‘Bt’ samples are from MON-89Ø34-3 event, and ‘RR×Bt’ samples are transgenic maize seedlings from MON-89Ø34-3 × MON-ØØ6Ø3-6 event. Bars indicate standard deviation and statistically significant values (p < 0.05) are represented by ‘*’
