Figure 2
Distribution of GFP, GFP-ELP and GFP-HFBI accumulation in independent transgenic tobacco lines. Dark green bars, plants with PBs. Gray bars, transgenic lines which did not display PB formation or which were not analyzed by confocal microscopy. Arrows identify transgenic plants analyzed by confocal microscopy. The X-axis represents independent transgenic T0 lines, and the Y-axis represents the amount of GFP produced by each transgenic T0 line as determined by dot-blot analysis of triplicate loading of each sample.
