Figure 3

Comparison of GFP accumulation in four transgenic tobacco groups. Each column represents the mean value of 24 independent transgenic plants regenerated for each transformed construct and error bars indicate the standard error of the mean. Dotted lines indicate pairwise significant differences at *P < 0.1; **P < 0.05 using the Wilcoxon-Mann–Whitney test between the two groups they delineate (e.g. the top dotted line represents a comparison of I64 GFP and 81V9 GFP-HFBI).
