摘要:
病程相关蛋白1(pathogenesis-related proteins1,PR1)是一类以基因家族形式存在的重要病程相关蛋白,在前期研究中,在小麦抗叶锈病近等基因系材料TaLr35中成功获得了1个小麦病程相关蛋白1基因TaLr35PR1,具有植物防御体系中的SCP保守结构域。利用生物信息学方法进一步明确,该基因含有信号肽,定位于细胞间隙,可能含有跨膜结构域,相对分子量为17.3 ku,与多个植物病程相关蛋白1序列具有较高同源性;利用半定量RT-PCR方法结合genetools、SPSS软件分析TaLr35PR1基因表达模式,结果表明,信号分子水杨酸(salicylic acid,SA)、脱落酸(abscisic acid,ABA)明显诱导该基因表达,且用信号分子预处理后接种叶锈菌,基因表达量明显增加;构建了TaLr35PR1基因的原核表达载体pEASY-PR1,在大肠杆菌中高效表达分子量约为17 ku的融合蛋白,明确其最佳诱导条件为在 0.8 mmol/L IPTG下于25 ℃诱导8 h。
