Emerging roles of the C-to-U RNA editing in plant stress responses

RNA editing is an important post-transcriptional event in all living cells. Within chloroplasts and mitochondria of higher plants, RNA editing involves the deamination of specific cytosine (C) residues in precursor RNAs to uracil (U). An increasing number of recent studies detail specificity of C-to-U RNA editing as an essential prerequisite for several plant stress-related responses. In this review, we summarize the current understanding of responses and functions of C-to-U RNA editing in plants under various stress conditions to provide theoretical reference for future research.
