In this study,realtime PCR or Northern blotting was employed to analyze the expression patterns of the CBP60g gene in wildtype Arabidopsis thaliana after Pseudomonas syringae and abiotic stress treatment.In addition,the expression of pathogeninduced genes in wildtype,cbp60g1 mutant and CBP60g overexpression plants after P.syringae inoculation were compared.The results showed:(1)Transcript of CBP60g was induced by P.syringae,high salt,cold and wounding treatment in wildtype plants.(2)The expression of pathogeninduced genes PR5 and AIG1 in the CBP60g overexpression plants was enhanced after P.syringae inoculation and was reduced in the mutant.(3)AtMYB2,an abioticstress induced gene reported previously,was also induced by Pst DC3000,and reached to a higher level in overexpression plants than in wildtype.Taken together,these results indicate that CBP60g involved in A.thaliana multiple stresses response.
