peppermint has considerable commercial value and widely cultivated for essential oil production, especially menthol. the aim of this study was to determine the quantitative expression of pulegone reductase (pr), menthofuran synthase (mfs) and limonene synthase (ls) genes in menthol biosynthesis pathway in mentha x piperita , using semiquantitative rt-pcr analysis and evaluating menthol producti...

RT-PCR has a detection limit 10–100 fold lower than protection-assay or northern hybridisation, respectively. The RT-ribonuclease PCR quantification technique of choice depends on the target sequence, the expected range of the mRNA amount present in the tissue, the degree of accuracy required, and whether quantification needs to be relative or absolute. Externally standardised RT-PCR with quant...

Lolium temulentum L. (Darnel ryegrass) is a valuable model grass species for the study of stress in forage and turf grasses. Gene expression analysis by quantitative real-time RT-PCR relies on the use of proper internal standards. The aim of this studywas to identify and evaluate reference genes for use in real-time quantitative RT-PCR for abiotic stress studies in L. temulentum. Partial sequen...

The analysis of differences in gene expression is dependent on normalization using reference genes. However, the expression of many of these reference genes, as evaluated by quantitative RT-PCR, is upregulated in acute pancreatitis, so they cannot be used as the standard for gene expression in this condition. For this reason, we sought to identify a stable reference gene, or a suitable combinat...
