Effect on Expression of PBZ 1 in Rice Suspension Cell by Different Stress-resistance Inducers

The effect on expression of PBZ 1 in rice suspension cell (Zhonghua 8)induced by the elicitors of fungal and salt pretreated with isoprothiolane (IPT) and abscisic acid (ABA) for 24 h were studied. The results showed that IPT or ABA or the two elicitors treatment could separately induce the expression of PBZ 1 in the suspension cell and without the expression of PBZ 1 in the control cells was observed treated with only the fungal and salt elicitors.The expression of PBZ 1 enhanced gradually from zero to three hours after treated with fungal elicitor and weakened gradually to zero within the same interval treated by salt elicitor. The expression intensity of PBZ 1 in rice cell treated only with IPT was obviously higher than that of induced by elicitor of fungal or salt pretreated by IPT for 24 h, and a continuance of high expression of PBZ 1 was observed from 0.5 to 3 h after treatment as well as by fungal elicitor after ABA treatment. It is obvious that IPT, ABA and fungal could induce the expression of PBZ 1 . The PBZ1 gene had active effects on the abiotic stresses with the exception of diseases.
