Histochemical analysis of the GUS activities directed by individual BnGPAT4 promoters in transgenic Arabidopsis. Similar GUS activities were observed in at least three independent transgenic lines for each construct. Only one transgenic line is shown in each panel. A to C, Five-day-old seedlings. GUS activities were driven by the three promoters of BnGPAT4-C1, BnGPAT4-C2, and BnGPAT4-A1, respectively. Bars = 0.5 mm. D to F, Ten-day-old seedlings. GUS activities were driven by the three promoters of BnGPAT4-C1, BnGPAT4-C2, and BnGPAT4-A1, respectively. Bars = 5 mm. G to L, Images represent similar GUS activities observed with all three BnGPAT4 promoters. G, GUS activity driven by the BnGPAT4-C2 promoter. H to L, GUS activities driven by the BnGPAT4-A1 promoter. G, A 20-d-old whole plant. H, Inflorescence stem. The inset shows an enlarged image of the inflorescence primordia. I, Cross-section of the main root. EN, Endodermis; EX, exodermis. Bar = 0.3 mm. J, Middle- to late-stage seeds in a silique. Bar = 0.5 mm. K, Dissected embryos and seed coats. WT, Wild type. Bar = 1 mm. L, Cross-section of a whole seed. Bar = 0.1 mm.
