Monitoring alternative splicing changes in arabidopsis circadian clock genes

Abstract

Posttranscriptional control makes an important contribution to circadian regulation of gene expression. In higher plants, alternative splicing is particularly prevalent upon abiotic and biotic stress and in the circadian system. Here we describe in detail a high-resolution reverse transcription-PCR based panel (HR RT-PCR) to monitor alternative splicing events. The use of the panel allows the quantification of changes in the proportion of splice isoforms between different samples, e.g., different time points, different tissues, genotypes, ecotypes, or treatments.
