GUS signals showing AtTT10 and AtDP1 promoter activities in transgenic pennycress seeds. Green mature stage of seeds of wildtype (A-C), transgenic line carrying AtTT10p:eGFP-GUS (D-F) and transgenic line carrying AtDP1p:eGFP-GUS (G-I) were cut along the longitudinal direction, and then manually separated into three parts, namely inner integument layers with peripheral endosperm tissue (A, D and G), outer integument layers (B, E and H), and embryos (C, F and I), and then treated with GUS staining. Scale bar = 0.5 mm
