摘要
实时定量PCR技术广泛应用于植物功能基因转录水平变化的研究,选择合适的内参基因进行相对定量分析是实验结果准确的关键因素。通过分析5个常用的内参基因(eEF-1α、18SrRNA、25SrRNA、Actin和UBQ5)在水稻(Oryza sativa)经过各种处理后表达的稳定性,结果表明,水稻经过机械损伤处理后eEF-1α基因的表达最稳定;二化螟处理后25SrRNA基因的表达最为稳定;稻纵卷叶螟处理后Actin基因的表达最稳定;两种刺吸式口器昆虫褐飞虱和白背飞虱危害后,UBQ5基因的表达最稳定。同时,利用OsHI-LOX基因在不同处理后的表达来评价这些内参基因。研究结果为水稻虫害诱导实时定量PCR分析中内参基因的选择提供了理论依据。
