Reverse transcription quantitative-PCR of three genes with high homology encoding 3-hydroxy-methylglutaryl-CoA reductase in rice
Reverse transcription followed by RT Q-PCR is useful for the systematic measurement of changes in gene expression. RT Q-PCR with two pairs of primers for each gene was used for relative expression of three genes with high homology encoding 3-hydroxy-methylglutaryl-CoA reductase (HMGR) in rice. At various growth stages of etiolated seedling and various times after UV-irradiation treatment, RT Q-PCR of each HMGR gene showed a consistent pattern of relative expression with the RT Q-PCR data, using two pairs of primers, giving a high degree of accuracy. Furthermore, the different expression levels of three HMGR genes in a sample were determined by diluting the cDNA concentration. These results indicate that RT Q-PCR with only one pair of primers for a gene can quantify the relative expression and that the high expression level of HMGR2 could be quantified in comparison to the low level of HMGR1 expression.
