Correlation between cry1Ac gene copies and cry1Ac protein content in transgenic sugarcane. a Scatter diagram of the cry1Ac protein vs. cry1Ac gene copies for 11 cry1Ac transgenic lines from the receptor variety FN15: A1, A2, A3, A4, A5, A6, B1, B2, B4, I2, and I4; the P-value and R value from the Pearson’s correlation analysis were 0.002, 0.818, respectively. b Scatter diagram of the cry1Ac protein vs. cry1Ac gene copies for six cry1Ac transgenic lines from the receptor variety ROC22: D1, D2, D4, K2, K3 and K5. The P-value and R value from the Pearson’s correlation analysis were 0.589 and − 0.282, respectively
