GUS staining pattern of transgenic plants expressing NtZIP5Bprom::GUS. GUS expression in 4-week-old transgenic and wild-type seedlings grown at control conditions (a) and in the Zn-deficient (−Zn) medium (b) for 4 days. Whole roots (a1, b1); whole leaves (a2, b2); Basal root part (b1a) and the cross section (b1-b); Root segment from the middle part with the protruding lateral root (b1-c) and the cross section (b1-d); root apex (b1-e) and cross sections at different positions as indicated by arrows (b1-f, b1-g, b1-h); the apical root part (b1-i) and the cross sections from the position indicated by arrow (b1-j); Cross section through the leaf blade (b3) and two chosen areas at higher magnification (b3-a, b3-b). Magnification bars in different colours represent indicated length
