Growth of mtp2 Seedlings Is Impaired and Zn Partitioning Altered on Zn-Deficient Medium.

(A) and (B) Images of representative 19-d-old wild-type (A) and mtp2 (B) seedlings on control (left) or Zn-deficient (−Zn) (right) agar-solidified media.

(C) and (D) Shoot fresh biomass (C) and root length (D) of wild-type and mtp2 seedlings as shown in (A) and (B).

(E) Shoot Zn partitioning in wild-type and mtp2 seedlings as shown in (A) and (B).

Bar graphs show arithmetic means ± sd (n = 17 seedlings [C] and [D]; n = 4 independent plates, from each of which tissues were pooled from 16 to 18 seedlings [E]). Distinct letters indicate significant differences (P < 0.05) according to a Bonferroni-corrected Student’s t test. Bars = 20 mm in (A) and (B).
