Examples of local auxin distribution in Arabidopsis thaliana marked by activity of auxin responsive promotor DR5. (A, B) DR5rev::GFP signal in preglobular and triangular stage embryos. (C) DR5rev::GFP signal at the position of incipient and developing flower primordia in the shoot apical meristem. (D) DR5rev::GFP signal in the developing flower bud. (E, F) DR5rev::GFP signal in a younger (E) and older (F) ovule primordium. (G) DR5rev::GFP in the columella initials region of a primary root. (H, I) Asymmetric expression of DR5::GUS in a hypocotyl of light stimulated seedling (H) and in the apical hook of an etiolated seedling (I). (J, K) DR5::GUS signal at the tip of a developing lateral root (J) and in the central meristem of a mature lateral root (K).
