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 …

The genomes in the two energy-converting organelles of plant cells, chloroplasts and
mitochondria, contain numerous 'errors' that are corrected at the level of RNA transcript …

The pentatricopeptide repeat (PPR) proteins form one of the largest protein families in land
plants. They are characterised by tandem 30–40 amino acid motifs that form an extended …

Members of the pentatricopeptide repeat (PPR) protein family are sequence-specific RNA-
binding proteins that play crucial roles in organelle RNA metabolism. Each PPR protein …

As a fascinating and complicated nanomotor, chloroplast ATP synthase comprises nine
subunits encoded by both the nuclear and plastid genomes. Because of its uneven subunit …

Most plant genes are interrupted by introns and the corresponding transcripts need to
undergo pre-mRNA splicing to remove these intervening sequences. Alternative splicing …

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 …

RNA editing processes are strikingly different in animals and plants. Up to thousands of
specific cytidines are converted into uridines in plant chloroplasts and mitochondria whereas …

In higher plants, the splicing of organelle-encoded mRNA involves a complex collaboration
with nuclear-encoded proteins. Pentatricopeptide repeat (PPR) proteins have been …

Cytoplasmic male sterility (CMS) is a widespread phenotype in plants, which present a
defect in the production of functional pollen. The male sterilizing factors usually consist of …
