摘要：
Cytosolic free calcium ion concentration ([Ca2+](cyt)) after a salicylic acid (SA)-stimulus was monitored in cells of the yeast Saccharomyces cerevisiae expressing apoaequorin, which constitutes a Ca2+-sensitive luminescent protein, aequorin, when combined with coelenterazine. SA induced a transient [Ca2+](cyt) elevation that was dependent on the concentration of SA and pH of the SA solution. The SA-induced [Ca2+](cyt) elevation was not reduced in Ca2+-deficient medium, suggesting that Ca2+ was mobilized from an intracellular Ca2+ store(s). Benzoic acid, butyric acid and sorbic acid did not induced a [Ca2+](cyt) elevation.
