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 کاملA single alteration 20 nt 5' to an editing target inhibits chloroplast RNA editing in vivo.
Transcripts of typical dicot plant plastid genes undergo C-->U RNA editing at approximately 30 locations, but there is no consensus sequence surrounding the C targets of editing. The cis-acting elements required for editing of the C located at tobacco rpoB editing site II were investigated by introducing translatable chimeric minigenes containing sequence -20 to +6 surrounding the C target of e...
متن کاملExpression of complementary RNA from chloroplast transgenes affects editing efficiency of transgene and endogenous chloroplast transcripts
The expression of angiosperm chloroplast genes is modified by C-to-U RNA editing. The mechanism for recognition of the approximately 30 C targets of editing is not understood. There is no single consensus sequence surrounding editing sites, though sites can be grouped into small 'clusters' of two to five sites exhibiting some sequence similarity. While complementary RNA that guides nucleotides ...
