Abstract

Ergosterol interacts with tobacco suspension (Nicotiana tabacum) cells and triggers pH changes of extracellular medium, oxidative burst and synthesis of phytoalexins. The use of several inhibitors of calcium channels (La3+, TMB-8, verapamil, ruthenium red, nifedipine) and a protein-kinase inhibitor (staurosporin) suggests that the elicitation with ergosterol includes the mobilization of internal calcium stores mediated by inositol 1,4,5-trisphosphate and serine/threonine protein kinases.
