Luminometer assays on plantlets regenerated from transgenic calli. Across 15 transgenic lines, the pUbi-luc plantlets had an average luminometer relative light units (RLU) reading of 20043 per mg of soluble protein. Across 15 transgenic lines, the pUbi-luc* transgenic plantlets had an average RLU of over 2205284 per unit soluble protein, representing an on average 110-fold increase over pUbi-luc lines. The 11 pUKR negative control transgenic lines yielded no detectable luciferase activity. The error bars represent the standard error of the mean.
