• Viene dimostrato che la dimetiltiourea (DMTU) previene, attraverso l’eliminazione di acqua ossigenata, l’inibizione della crescita e l’accumulo di putrescina in seguito al trattamento con spermidina di radici di semenzali di mais. (literal)

Abstract

• Inhibition of root growth and accumulation of putrescine caused by exogenous spermidine in roots of maize seedlings (Zea mays L., cv Samodek) were partially prevented by a concomitant treatment with dimethylthiourea (DMTU), that traps H2O2 produced from spermidine by the activity of polyamine oxidase (PAO) in the apoplast. Treatment with spermidine caused a strong increase of ascorbate peroxidase (APX) gene expression, that was induced to a lesser extent by removing spermidine-generated H2O2 by DMTU. Over-expression of APX was associated with increased APX activity in spermidine-treated seedlings whereas the addition of DMTU to spermidine completely prevented spermidine-induced increase of APX activity. Thus, DMTU permitted the demonstration that exogenous spermidine supplied to maize seedlings causes an oxidative stress and induces APX, a key enzyme of the antioxidant defence mechanism, through H2O2, a spermidine catabolic product.
