Abstract

This article describes the analysis of Arabidopsis RNA by reverse transcriptase-polymerase chain reaction (RT-PCR). RNA is first reverse-transcribed into cDNA, which is then amplified by PCR. This method is quick and easy. Although RT-PCR can be performed quantitatively, it is often technically challenging to obtain highly accurate results. We recommend the use of an RT-PCR kit; the procedure given here is adapted from a commercial kit protocol. In the PCR step, it is advisable to use oligonucleotide primers that span at least one intron. In this way, amplification of any contaminating genomic DNA is readily detected, because the product derived from genomic DNA will be larger than the cDNA product. Expression levels are determined by comparing against a gene that is expressed fairly uniformly, such as the ubiquitin gene UBQ10.
