Cortical-specific auxin response in CO2::ΔARF5 plants. Visualization of the auxin response in the roots of DR5::VENUS (top) and CO2::ΔARF5/DR5::VENUS plants (bottom) grown in 1/2 MS solid medium for 7 days (left, longitudinal sections; middle, high-magnification images of the longitudinal sections; right, cross-sections). White arrows indicate VENUS fluorescent signals in the cortical cells of CO2::ΔARF5 plants. Green and red fluorescence correspond to VENUS and PI signals, respectively. Ep, epidermis; Co, cortex; E, endodermis; P, pericycle; V, vasculature. Scale bars = 20 μm.
