Accumulation of green fluorescent protein in various subcellular compartments, in the presence or absence of an elastin-like polypeptide tag. The concentration of green fluorescent protein (GFP) was measured by quantitative fluorometric analysis from leaf sectors harvested from Nicotiana benthamiana plants 4 days post-agro-infiltration. Each column represents the mean value (n = 8), and the standard error of the mean is represented with error bars. Columns not connected with the same letter are significantly different (P < 0.05) from each other using Tamhane's T2 test. TSP, total soluble protein.
