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 …

Like their nuclear counterpart, the plastid and mitochondrial genomes of plants have to be
faithfully replicated and repaired to ensure the normal functioning of the plant. Inability to …

The chloroplast genome encodes proteins required for photosynthesis, gene expression,
and other essential organellar functions. Derived from a cyanobacterial ancestor, the …

Present in the genomes of bacteria and eukaryotic organelles, group II introns are an
ancient class of ribozymes and retroelements that are believed to have been the ancestors …

Since the endosymbiotic origin of chloroplasts from cyanobacteria 2 billion years ago, the
evolution of plastids has been characterized by massive loss of genes. Most plants and …

Group II introns have attracted considerable attention as ribozymes, mobile genetic
elements and possible progenitors of nuclear spliceosomal introns. Major advances in …

Plastids (chloroplasts) possess their own genetic information and consequently, express
heritabletraits. The plastid genome (plastome) occurs at high copy numbers, with up to …

The pentatricopeptide repeat (PPR) is a degenerate 35–amino acid repeat motif that is
widely distributed among eukaryotes. Genetic, biochemical, and bioinformatic data suggest …

Abstract The psbB-psbT-psbH-petB-petD operon of higher plant chloroplasts is a
heterogeneously composed transcriptional unit that undergoes complex RNA processing …

Introns and spacers are a rich and well-appreciated information source for evolutionary
studies in plants. Compared to coding sequences, the mutational dynamics of introns and …
