additional information | downregulation of ALN and UO (uricase) genes impairing allantoin accumulation in Cd-treated Col-0 roots. In enzyme-deficient aln-3 roots, allantoin content increases nearly 2fold at 1 mM CdCl2 but is similar to untreated roots at 1.5 mM CdCl2. T-DNA insertions in allantoinase cause the constitutive accumulation of allantoin resulting in plant resistance to different abiotic stresses such as drought, salinity (NaCl), and heavy metal cadmium toxicity | Arabidopsis thaliana |

malfunction | T-DNA insertions in allantoinase cause the constitutive accumulation of allantoin resulting in plant resistance to different abiotic stresses such as drought, salinity (NaCl), and heavy metal cadmium toxicity. High concentration of allantoin in allantoinase-negative mutant (aln-3) leaves alleviates cadmium toxicity via inducing antioxidant mechanisms in these plants. In contrast with wild-type leaves, high levels of Cd in Col-0 roots reduces transcript abundance of uricase, leading to a significant decline in allantoin level of treated roots at 1000 and 1500 mM CdCl2, molecular mechanism underlying allantoin content of root in response to Cd stress, overview. Root elongation is reduced in Cd-treated wild-type but not enzyme-deficient plants. Despite higher Cd content, aln-3 roots contain lower reactive oxygen species concentrations. Antioxidant enzymes are more active in aln-3 roots following Cd treatment | Arabidopsis thaliana |
