Expression pattern of representative AtVLN::GUS transgenic plants. A, C, E, G, I, K, L, and N are from AtVLN 1::GUS plants; B, D, F, H, J, and M are from AtLVN 2::GUS plants. A and B, Entire seedling. C and D, Cotyledon. E and F, Roots. G and H, Root, high magnification; C, cortex; P, pericycle; V, vasculature. I and J, Root tip, high magnification. K, Flower. L and M, Stipule. N, Silique. GUS staining was performed for 1 h in I, K, and N; for 2 h in E, I, F, J, and H; and for 24 h in B, D, and M. Scale bars represent 1 mm in A and E; 100 μm in B through D, F, H through K, and N; and 10 μm in G, L, and M.
