Abstract: To study the expression of grape stress tolerance gene (CAN70200.1),a 1 354 bp promoter fragment (named as PCAN) upstream of the gene CAN70200.1 was isolated by using PCR technology.Promoter sequence was analyzed by the database of PlantCARE and PLACE.The result showed that the PCAN sequence contained basic elements CAAT-box,TATA-box and some cis-acting elements that response to abiotic stresses,light and plant hormones.To verify the expression pattern of the promoter,the PCAN fragment was fused with GUS reporter gene located on pCAMBIA1391Z to construct a plant expression vector p1391Z-CAN,followed by transformation into tobacco by Agrobacterium-meditated method.The expression activity of PCAN promoter reached highest at 120 min after drought stress treatment or at 30-60 min under 4℃ cold treatment condition,indicated that the PCAN promoter could express under the condition of treatments with cold and drought.

Key words: Grape, PCAN promoter, Stress induction expression, GUS assay
