Quantification of GUS expression in Nicotiana tabacum using ImageJ 1.50.
The four bar graphs show: pGreen0029 (−ve control), GUS expression from the empty vector; 35S-GUS (+ve control), GUS expression under 35S promoter; CP-GUS, expression of GUS under BBTV-Coat protein promoter; and NSP-GUS, GUS expression under BBTV-Nuclear shuttle protein promoter. Each bar represents the mean +/− standard error of three measurements; dpi = days post infection.
