Glucosinolate-Derived Isothiocyanates Inhibit Arabidopsis Growth and the Potency Depends on Their Side Chain Structure.

ABSTRACT: Isothiocyanates (ITCs), the biologically important glucosinolate breakdown products, can present health-promoting effects, play an important role in plant defense and affect plant cellular mechanisms. Here, we evaluated the biological effects of ITCs on Arabidopsis thaliana by assessing growth parameters after long-term exposure to low concentrations of aliphatic and aromatic ITCs, ranging from 1 to 1000 µM. Treatment with the aliphatic allylisothiocyanate (allyl-ITC) led to a significant reduction of root length and fresh weight in a dose-dependent manner and affected the formation of lateral roots. To assess the importance of a hormonal crosstalk in the allyl-ITC-mediated growth reduction, the response of auxin and ethylene mutants was investigated, but our results did not allow us to co
