Figure 4From: Characterization of bacterial-type phosphoenolpyruvate carboxylase expressed in male gametophyte of higher plantsActivities of Atppc1-4 promoters in different organs. Histochemical localization of GUS reporter gene expression in rosette leaf (A, E, I, M), root (B, F, J, N), flower buds (C, G, K, O), and mature pollen (D, H, L, P) driven by the Atppc1 (A-D), Atppc2 (E-H), Atppc3 (I-L), or Atppc4 (M-P) promoter. Bars = 0.5 mm in A, C, E, G, I, K, M, and O; 50 μm in B and N; 100 μm in F and J; and 10 μm in D, H, L, and P.Back to article page
