Abstract

Summary RNA editing is a crucial modification in plants' organellar transcripts that converts cytidine to uridine (C‐to‐U; and sometimes uridine to cytidine) in RNA molecules. This post‐transcriptional process is controlled by the PLS‐class protein with a DYW domain, which belongs to the pentatricopeptide repeat (PPR) protein family. RNA editing is widespread in land plants; however, complex thalloid liverworts (Marchantiopsida) are the only group reported to lack both RNA editing and DYW‐PPR protein. The liverwort Cyathodium cavernarum (Marchantiopsida, Cyathodiaceae), typically found in cave habitats, was newly found to have 129 C‐to‐U RNA editing sites in its chloroplast and 172 sites in its mitochondria. The Cyathodium genus, specifically C. cavernarum, has a large number of PPR editing factor genes, including 251 DYW‐type PPR proteins. These DYW‐type PPR proteins may be responsible for C‐to‐U RNA editing in C. cavernarum. Cyathodium cavernarum possesses both PPR DYW proteins and RNA editing. Our analysis suggests that the remarkable RNA editing capability of C. cavernarum may have been acquired alongside the emergence of DYW‐type PPR editing factors. These findings provide insight into the evolutionary pattern of RNA editing in land plants.
