Expression of MT1a and MT2a in Arabidopsis roots and leaves. The hybridization signal ranged from purple to dark blue. A, B, G, H, and I, Sections probed with MT1a antisense; C and M, sections probed with MT1a sense; D, E, J, K, and L, sections probed with MT2a antisense; F and N, sections probed with antisense probe with MT2a sense; O, section probed with antisense probe for the chloroplast-specific transcript psbO. All roots sections are from 6-d-old seedlings grown without excess copper. A and D, Longitudinal sections. A and D, Root-tip sections. B, C, E, and F correspond to sections through the maturation region. All leaf sections are from the youngest leaves of 2-week-old untreated plants (G, J, M, and O) or plants treated with excess copper (H, I, K, and L). Inset in I corresponds to a higher magnification of one of the vascular bundles. e, Epidermis; c, cortex; s, stele; t, trichome; v, vascular bundle. Arrows, Locations of hybridization signal.
