From: The upregulation of thiamine (vitamin B1) biosynthesis in Arabidopsis thaliana seedlings under salt and osmotic stress conditions is mediated by abscisic acid at the early stages of this stress response

Figure 5

Changes in the levels of total thiamine (A) and of individual thiamine compounds (B) in the leaves of Arabidopsis seedlings treated for 48 h with various plant hormones. Seedlings were treated with 100 μM abscisic acid (ABA), 100 μM jasmonic acid (JA) or 200 μM salicylic acid (SA) and assayed for thiamine compounds as described in Figure 3. Seedlings maintained on growth medium without any added hormone served as the control (C). The asterisk indicates a statistically significant difference when compared with the control samples (t-test, P < 0.05).
