RNA editing in plastids is known to be required for embryogenesis, but no single editing
event had been shown to be essential. We show that the emb2261-2 mutation is lethal …

In chloroplasts and plant mitochondria, specific cytidines in mRNAs are posttranscriptionally
converted to uridines by RNA editing. Editing sites are recognized by nucleus-encoded RNA …

Plastid‐encoded genes are coordinately transcribed by the nucleus‐encoded RNA
polymerase (NEP) and the plastid‐encoded RNA polymerase (PEP). Resulting primary …

Chloroplast gene expression involves the participation of hundreds of pentatricopeptide
repeat (PPR) RNA binding proteins, and proteins in the PLS subfamily typically specify sites …

After transcription, most chloroplast precursor RNAs undergo further post-transcriptional
processing including cleavage, editing, and splicing. Previous investigation has shown that …

Abstract Background C-to-U RNA editing in mitochondria and chloroplasts and the nuclear-
encoded, RNA-binding PPR proteins acting as editing factors present a wide field of co …

C-to-U editing of transcripts in plant organelles is carried out by small (< 400 kD) protein
complexes called editosomes. Recognition of the proper C target for editing is mediated by …

Photosynthesis occurs mainly in chloroplasts, whose development is regulated by proteins
encoded by nuclear genes. Among them, pentapeptide repeat (PPR) proteins participate in …

RNA editing is converting hundreds of cytosines into uridines during organelle gene
expression of land plants. The pentatricopeptide repeat (PPR) proteins are at the core of this …

RNA editing is essential for compensating for defects or mutations in haploid organelle
genomes and is regulated by numerous trans-factors. Pentatricopeptide repeat (PPR) …
