摘要: 为通过转基因植物等方法分析玉米ZmCBL2-2基因在耐逆性中的功能,运用RT-PCR(Reverse transcriptionPCR)方法克隆了该基因的编码区cDNA片段,并将其构建到植物表达载体p3301(pCAMBIA3301)上。同时,运用荧光实时定量PCR(Real-time quantitative PCR,RT-qPCR)技术对玉米幼苗期该基因在高盐、低温和养分缺乏等6种非生物胁迫下的表达动态进行了分析,发现其对于缺N、低K、低温、外源ABA(Abscisic acid)和水分胁迫均有显著的应答反应,而对于盐胁迫无明显的响应。

Abstract: To analyze the role of ZmCBL2-2 gene in the tolerance of maize to abiotic stresses by methods such?as transgenic plants,the complete coding region cDNA fragment of the gene was cloned by reverse transcription polymerase chain reaction (RT-PCR) and constructed into the plant expression vector p3301 (pCAMBIA3301). Moreover,the expression profiles of ZmCBL2-2 under six abiotic stresses such as high salinity,low temperature and nutritional deficiency were analyzed by real time quantitative PCR (RT-qPCR) method,and it was found that the gene?responded significantly to nitrogen deprivation,low potassium,low temperature,exogenous abscisic acid (ABA) and?water stress,but did not respond obviously to salt stress.
