实时荧光定量PCR(qPCR)技术被广泛应用于基因表达分析,选用合适的内参基因是运用该技术准确分析目标基因表达变化的前提。本研究以珙桐不同器官为材料,采用qPCR技术分析了珙桐中6个管家基因(ACT7、eIF、 EF1a、GAPDH、 β-TUB、18S rRNA)及2个新内参基因(CAC、TIP41),共8个候选内参基因的表达情况,并利用geNorm、NormFinder和Best- Keeper3种软件对候选内参基因的表达稳定性进行了评价。结果表明, CAC和ACT7在珙桐营养器官与生殖器官中均表达稳定,且新内参基因CAC的表达稳定性优于ACT7; GAPDH、EF1a、18S rRNA和TIP41在珙桐营养器官与生殖器官中均表达不稳定,尤其是GAPDH和18S rRNA的表达稳定性...

Real-time quantitative PCR (qPCR) has been widely used in gene expression analysis. Selection of suitable reference genes is the first step in analyzing the expression variation of target genes accurately by qPCR. In the present study, we analyzed the expression patterns of eight candidate reference genes including six housekeeping genes (ACT7, eIF, EF1a, GAPDH, β-TUB and 18S rRNA) and two novel reference genes (BADH and TIP41) in different organs of dove tree (Davidia involucrata) by qPCR. Three softwares, geNorm, NormFinder and BestKeeper, w...
