Regulation of RNA Editing in Chloroplast
RNA editing is an important process involved in the modification of nucleotides in the transcripts of a large number of functional genes. RNA editing results in the restoration of conserved amino acid residues for protein function in plants. In this review, I only describe and discuss the identified RNA editing and the RNA editing associated regulation in chloroplast, including cytidine-to-urid...
متن کاملChloroplast RNA editing by pentatricopeptide repeat proteins.
Pentatricopeptide repeat (PPR) proteins function in multiple processes in mRNA maturation in plastids and mitochondria (reviewed in Schmitz-Linneweber and Small, 2008). RNA maturation in chloroplasts is complex, and PPR proteins act in cisand trans-splicing, translation, RNA cleavage, RNA stabilization, and RNA editing. This large protein family, with 450 members in Arabidopsis, is characterize...
متن کاملThe Chloroplast Genome of Pellia endiviifolia: Gene Content, RNA-Editing Pattern, and the Origin of Chloroplast Editing
RNA editing is a post-transcriptional process that can act upon transcripts from mitochondrial, nuclear, and chloroplast genomes. In chloroplasts, single-nucleotide conversions in mRNAs via RNA editing occur at different frequencies across the plant kingdom. These range from several hundred edited sites in some mosses and ferns to lower frequencies in seed plants and the complete lack of RNA ed...

متن کاملEvolution of RNA editing in trypanosome mitochondria.
Two different RNA editing systems have been described in the kinetoplast-mitochondrion of trypanosomatid protists. The first involves the precise insertion and deletion of U residues mostly within the coding regions of maxicircle-encoded mRNAs to produce open reading frames. This editing is mediated by short overlapping complementary guide RNAs encoded in both the maxicircle and the minicircle ...
