Quantitative Analysis of RNA Editing at Specific Sites in Plant Mitochondria or Chloroplasts Using DNA Sequencing.

Abstract

Cytidine-to-uridine (C-to-U) RNA editing is one of the most important post-transcriptional RNA processing in plant mitochondria and chloroplasts. Several techniques have been developed to detect the RNA editing efficiency in plant mitochondria and chloroplasts, such as poisoned primer extension (PPE) assays, high-resolution melting (HRM) analysis, and DNA sequencing. Here, we describe a method for the quantitative detection of RNA editing at specific sites by sequencing cDNA from plant leaves to further evaluate the effect of different treatments or plant mutants on the C to U RNA editing in mitochondria and chloroplasts.
