摘要: 旨在获得香樟(Cinnamomum camphora L.)在不同非生物胁迫下表达稳定的内参基因,以香樟实生苗为材料,利用实时定量PCR(quantitative real-time polymerase chain reaction,qRT-PCR)技术研究分析了两个香樟候选内参基因CcACTc和CcEF1α在不同非生物胁迫下的表达量,并通过BestKeeper软件对CcACTc和CcEF1α的稳定性进行了分析。结果表明,在低温处理中,CcACTc的稳定性较好,在干旱、高盐和ABA处理中则CcEF1α的稳定性较好,并且其在低温处理中也相对稳定。由此可知,CcEF1α更适合作为内参基因应用于香樟非生物胁迫相关基因的定量分析。

Abstract: This study is to obtain the optimal reference genes of Cinnamomum camphora under different abiotic stresses. The expression level and expression stability of two candidate reference genes CcACTc and CcEF1α in C. camphora under various abiotic stresses were analyzed using quantitative real-time polymerase chain reaction(qRT-PCR)technique and BestKeeper software,respectively. The results indicated that,CcEF1α was relatively stable under low temperature treatment,and performed higher stability under other abiotic stress,such as drought,high salinity and ABA treatment compared to CcEF1α. Accordingly,CcEF1α is a considerable reference gene for quantitative analysis of stress-related genes in C. camphora.
