th in roots under salt stress. Thymol-attenuated oxidative stress may be resulted from the activationof anti-oxidative capacity, including both enzymatic and non-enzymatic system. Thymol treatment significantlydecreased Na+ content in root cells upon salt stress, which might be ascribed to the upregulation of OsSOS1 (saltoverly sensitive 1) facilitating Na+ exclusion. In addition, thymol stimulated the expression of genes encodingtonoplast OsNHX (Na+/H+ antiporter), which may help root cells to compartmentalize Na+ in vacuole. Theresults of these works evidenced that t
