Reference Gene Selection in Plant Real-time Quantitative Reverse Transcription PCR (qRT-PCR)

Real-time quantitative RT-PCR (qRT-PCR) technology, with quantitative accuracy, high sensitivity and high-throughput characteristics, has been widely used in gene expression analysis. Based on the relative quantitative analysis, qRT-PCR data must be normalized with one or more proper and stable internal reference genes. House-keeping genes are customarily used as endogenous references for relative quantification. But not a single gene can act as a universal reference reported so far. Most of the traditional housekeeping genes are unable to ensure accurate normalization in qRT-PCR. Based on the tremendous gene-chip expression data and public deposited EST data, new reference genes with superior stability were selected and verified with qRT-PCR. The research progress of reference genes in plant qRT-PCR was reviewed and aspects to be considered in future reference gene selection were also discussed.
