An Arabidopsis pentatricopeptide repeat protein, SUPPRESSOR OF VARIEGATION7, is required for FtsH-mediated chloroplast biogenesis.
The Arabidopsis (Arabidopsis thaliana) yellow variegated2 (var2) mutant has green- and white-sectored leaves due to loss of VAR2, a subunit of the chloroplast FtsH protease/chaperone complex. Suppressor screens are a valuable tool to gain insight into VAR2 function and the mechanism of var2 variegation. Here, we report the molecular characterization of 004-003, a line in which var2 variegation ...
متن کاملPPR8522 encodes a chloroplast-targeted pentatricopeptide repeat protein necessary for maize embryogenesis and vegetative development
The pentatricopeptide repeat (PPR) domain is an RNA binding domain allowing members of the PPR superfamily to participate in post-transcriptional processing of organellar RNA. Loss of PPR8522 from maize (Zea mays) confers an embryo-specific (emb) phenotype. The emb8522 mutation was isolated in an active Mutator (Mu) population and co-segregation analysis revealed that it was tightly linked to a...
متن کاملChloroplast RNA-binding and pentatricopeptide repeat proteins.
Chloroplast gene expression is mainly regulated at the post-transcriptional level by numerous nuclear-encoded RNA-binding protein factors. In the present study, we focus on two RNA-binding proteins: cpRNP (chloroplast ribonucleoprotein) and PPR (pentatricopeptide repeat) protein. These are suggested to be major contributors to chloroplast RNA metabolism. Tobacco cpRNPs are composed of five diff...
متن کاملRice OGR1 encodes a pentatricopeptide repeat-DYW protein and is essential for RNA editing in mitochondria.
RNA editing is the alteration of RNA sequences via insertion, deletion and conversion of nucleotides. In flowering plants, specific cytidine residues of RNA transcribed from organellar genomes are converted into uridines. Approximately 35 editing sites are present in the chloroplasts of higher plants; six pentatricopeptide repeat genes involved in RNA editing have been identified in Arabidopsis...
متن کاملArabidopsis EMB1990 Encoding a Plastid-Targeted YlmG Protein Is Required for Chloroplast Biogenesis and Embryo Development
In higher plants, embryo development originated from fertilized egg cell is the first step of the life cycle. The chloroplast participates in many essential metabolic pathways, and its function is highly associated with embryo development. However, the mechanisms and relevant genetic components by which the chloroplast functions in embryogenesis are largely uncharacterized. In this paper, we de...
