Figure 6. Effect of 50 µM Al on the transcript levels of gene expression encoding selected proteins of three barley genotypes exposed to 50 µM Al for 24 h.

(A) S-adenosylmethionine synthase 3 (SAMS3, spot U1); (B) methionine synthase (MeSe, spot U2); (C) glutamine synthetase (GS, spot U4); (D) γ-glutamylcysteine synthetase (γ-GCS, spot U5) and (E) ATP synthase beta subunit proteins in roots (spot U9) of three barley genotypes exposed to 50 µM Al for 24 h. Error bars represent SD values (n = 3).
