| Description | Low molecular lipid substances represent specific elicitors of plant defence reaction. We studied the elicitation mechanism by means of several inhibitors of calcium channels (La3+, verapamil, nifedipin, TMB-8 and ruthenium red) and fluorescence confocal microscopy with calcium green and compared the effect on the signal pathways induced by cryptogein, a typical fungal proteinaceous elicitor the receptor of which is localized on the plasma membrane, with ergosterol. The results suggest that the binding of ergosterol to an unknown receptor results in a mobilization of internal calcium stores (probably IP3 dependent) rather than in the effect on the plasma membrane channels. |
