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 3

Changes in the levels of thiamine and its phosphate esters in Arabidopsis seedlings in response to abiotic stress conditions. Nine day old seedlings were maintained for 48 h on growth medium supplemented with 0.2 μM PQ, 200 mM NaCl or 200 mM SOR. Thiamine compounds were assayed in seedling leaves by RP-HPLC via post-column oxidation to thiochrome derivatives and fluorometric detection. The asterisk indicates a statistically significant difference when compared with the control samples (t-test, P < 0.05).
