In order to illuminate the effect of calcium on the IAA signal transduction, we studied the expression of eight SlIAA genes which were up-regulated by calcium during the abscission after short-term (1 h) and long-term (16 h) treatments with calcium, IAA and calcium inhibitors. The results indicated that calcium induced SIIAAs expression in 1 h at low concentration, EGTA affected little SIIAAs expression; it also increased IAA-induced transcript level of SIIAAs, TFP (named trifluoperazine) decreased most SIIAAs expression below the level of calcium combined with IAA-induced expression, except for SlIAA17. Long-term treatment of calcium or calcium inhibitors suppressed some SIIAAs expression, whereas TFP enhanced all SIIAAs expression. Interestingly, SlIAA29 was induced by most treatments excluding 16 h EGTA.
