| Abstract | Previous results have shown that both nitric oxide (NO) and hydrogen peroxide (H(2)O(2)) play crucial roles in the promotion of adventitious root development in explants of marigold (Tagetes erecta L.). In this study, the involvement of NO and H(2)O(2) in indole-3-butyric acid (IBA)-induced adventitious root development in marigold explants, and the order of action of these molecules in the signal transduction pathway were investigated. The results indicated that, like NO and H(2)O(2), IBA-induced adventitious rooting occurred in a dose-dependent manner. Two parameters of root growth in explants treated simultaneously with IBA and H(2)O(2) were significantly higher than those in explants treated with IBA or H(2)O(2) alone, suggesting that IBA and H(2)O(2) may act synergistically to mediate adventitious rooting. NO and H(2)O(2) were pre-requisites for the adventitious rooting induced by IBA. Moreover, treatment with IBA enhanced the endogenous levels of NO and H(2)O(2) in explants, indicating that the induction of adventitious roots by IBA occurred through enhancing the levels of NO and H(2)O(2). NO and H(2)O(2) may be downstream signal molecules in the auxin signalling cascade, and NO may be involved as an upstream signalling molecule for H(2)O(2) production. |
