Fig. 9From: Effect of herbivore stress on transgene behaviour in maize crosses with different genetic backgrounds: cry1Ab transgene transcription, insecticidal protein expression and bioactivity against insect pestsSpearman’s rank correlation coefficient (Rs) between transgene transcription activity (relative units) and Cry1Ab concentration (µg/g dwt) in damaged and undamaged plants across different genetic backgrounds from South Africa. The feeding damage was induced by S. littoralis larvae. Damaged maize plants (Rs = 0.55, P = 0.08); undamaged maize plants (Rs = 0.17, P = 0.190)Back to article page
