摘      要：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 *** results indicated that calcium induced SlIAAs expression in 1 h at low concentration,EGTA affected little SlIAAs expression;it also increased IAA-induced transcript level of SlIAAs,TFP（named trifluoperazine） decreased most SlIAAs expression below the level of calcium combined with IAA-induced expression,except for ***-term treatment of calcium or calcium inhibitors suppressed some SlIAAs expression,whereas TFP enhanced all SlIAAs ***,SlIAA29 was induced by most treatments excluding 16 h EGTA.
