| Summary: | Glucosinolates are secondary metabolites of the Brassicales, playing a role in plant protection and as health-promoting compounds. Here, Na<sub>2</sub>SO<sub>4</sub> was used to modulate the aliphatic glucosinolate content in different organs of <i>Eruca sativa</i> Mill. In flowers, which accumulate the highest amount of glucosinolates, Na<sub>2</sub>SO<sub>4</sub> increased the concentration of glucoraphanin, in roots of glucoerucin and in apical leaves it doubled the amount of dimeric 4-mercaptobutyl glucosinolate. The biosynthetic gene <i>Branched-Chain Aminotransferase 4</i> was also induced in roots at the highest salt concentration, while in leaves all tested genes biosynthetic genes were downregulated or unaffected. <i>Cytochromes P450 83A1 monooxygenase</i> was downregulated at the highest salt concentration in all organs. Overall, <i>E. sativa</i> is a reliable source of glucosinolates, which can be modulated with Na<sub>2</sub>SO<sub>4</sub>. |
