Fig. 4From: Thymol ameliorates ammonium toxicity via repressing polyamine oxidase-derived hydrogen peroxide and modulating ammonium transporters in rice rootThymol repressed ammonium-induced upregulation of PAOs in rice seedlings. a and b Relative expression level of PAOs in NH4Cl-treated seedlings with respect to control. c and d Relative expression level of PAOs in seedlings treated with NH4Cl + thymol with respect to NH4Cl treatment alone. Red and green indicate up-regulation and down-regulation, respectivelyBack to article page
