摘要: 为了研究葡萄抗逆基因(CAN70200.1)的表达特性,采用PCR技术从葡萄中克隆了CAN70200.1基因上游一段长度为1354 bp的启动子片段,命名为PCAN。采用PlantCARE和PLACE启动子在线预测工具分析表明,PCAN启动子序列具有CAAT-box、TATA-box基本的顺式作用元件和一些参与非生物胁迫、光和植物激素应答相关的顺式作用元件。为验证启动子的表达特性,将PCAN启动子连接到pCAMBIA1391Z载体GUS基因的上游,构建成植物表达载体p1391Z-CAN,并通过农杆菌介导法转化烟草,经PCR鉴定,获得转基因植株。对转基因烟草植株进行逆境胁迫处理发现,在干旱处理120 min后,PCAN启动子活性达到最强;而4℃低温处理30~60 min时,PCAN启动子活性达到最强,表明PCAN启动子具有低温和干旱胁迫诱导表达特性。

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
