Abstract
Steady-state mRNA levels are determined by both the rates of transcription and degradation. Regulation of mRNA stability and/or degradation are key factors that can significantly affect mRNA levels and its biological functions. mRNA stability can be measured indirectly after transcription inhibition. This protocol described a rapid and sensitive method of mRNA stability measurement through quantitative reverse transcription PCR (RT-qPCR) after inhibition of RNA transcription by cordycepin in Arabidopsis seedlings.
