From: Zn/Cd status-dependent accumulation of Zn and Cd in root parts in tobacco is accompanied by specific expression of ZIP genes

Fig. 5

Expression of ZIP genes in the apical, middle and basal parts of roots from plants after short-term exposure to Cd. 5.5-week old plants grown in the quarter-strength Knop’s medium were exposed to the control medium containing 1 μM Zn with (1 μM Cd) or without Cd for 3 h, 1 day, or 3 days. Expression of NtZIP2A (a), NtZIP5A (b), NtZIP5B (c), NtIRT1 (d), NtIRT1-like (e), NtZIP1-like (f), NtZIP8 (g), NtZIP4A (h), NtZIP4B (i), NtZIP5-like (j), NtZIP11 (k). Gene expression was normalized to the PP2A level. Values correspond to arithmetic means ±SD (n = 3); those with the ratio greater than 2 are considered significantly different
