Maize (Zea mays L. cv. Thermo) root segments were treated for 24 h with 100 μg mL−1 of zearalenone and its derivatives α- and β-zearalenol. The mycotoxin treatment resulted in cell death which was evident by Evans blue staining and was accompanied by DNA release/fragmentation. Mycotoxin-induced programmed cell death (MPCD) was abolished by sub-micromolar concentrations of caspase-specific peptide...
This study is aimed at the responses of grapevine adventitious root explants to zinc (Zn2+) excess. Within 24 h Zn2+ induced oxidative burst in concentration-dependent manner. The time course analysis revealed biphasic response in superoxide (O2-.) production. Hydrogen peroxide (H2O2) accumulation rose gradually within 24 h. Enhanced Zn2+ concentrations did not induce progression of cell death. Immediately...
Root growth of the seedlings of maize cultivars Premia and Blitz exposed to 2 μM cadmium (Cd), nickel (Ni) or both metals acting simultaneously (Cd + Ni) for 72 h was significantly reduced but not ceased. The effect was more pronounced in the seedlings of the cv. Blitz. The heavy metals (HMs) contents increased significantly in the roots. Simultaneous application of metals had an antagonistic effect...
Plant hormones operate in a very complex network where they regulate and control different vital mechanisms. They coordinate growth, development and defense via signaling involving different interactions of molecules. Activation of molecules responsible for regulation of plant immunity is mainly provided by salicylic and jasmonic acid signaling pathways. Similar to the signaling of these defense-associated...
Grapevine (Vitis vinifera L., cv. Limberger) leaf tissues and suspension-cultured cells were induced to undergo programmed cell death (PCD) by exogenously added methyl jasmonate (MeJA). The elicitor signaling pathway involved in MeJA-induced PCD was further investigated using pharmacological, biochemical and histological approaches. Pharmacological dissection of the early events preceding the execution...
