The central dogma in biology defines the flow of genetic information from DNA to RNA to
protein. Accordingly, RNA molecules generally accurately follow the sequences of the genes …

Pentatricopeptide repeat (PPR) proteins constitute one of the largest protein families in land
plants, with more than 400 members in most species. Over the past decade, much has been …

Plant organellar RNA metabolism is run by a multitude of nucleus-encoded RNA-binding
proteins (RBPs) that control RNA stability, processing, and degradation. In chloroplasts and …

Chloroplasts evolved from an ancient cyanobacterial endosymbiont more than 1.5 billion
years ago. During subsequent coevolution with the nuclear genome, the chloroplast …

RNA editing by cytidine (C) to uridine (U) conversions is widespread in plant mitochondria
and chloroplasts. In some plant taxa,“reverse” U-to-C editing also occurs. However, to date …

Abstract RNA C-to-U editing in organelles is essential for plant growth and development;
however, the underlying mechanism is not fully understood. Here, we report that …

Chloroplasts are plant organelles that carry out photosynthesis, produce various
metabolites, and sense changes in the external environment. Given their endosymbiotic …

Flowering plants convert many hundreds of organelle cytidines (Cs) to uridines (Us) during
post-transcriptional RNA editing. Pentatricopeptide repeat (PPR) proteins dictate specificity …

RNA editosomes selectively deaminate cytidines to uridines in plant organellar transcripts—
mostly to restore protein functionality and consequently facilitate mitochondrial and …

During development or under stress, chloroplasts generate signals that regulate the
expression of a large number of nuclear genes, a process called retrograde signaling …
