Pentatricopeptide repeat (PPR) proteins constitute one of the largest protein families in land
plants, with more than 400 members in most species. Over the past decade, much has been …

Pentatricopeptide repeat (PPR) proteins are a large family of modular RNA-binding proteins
which mediate several aspects of gene expression primarily in organelles but also in the …

Although research has determined that reactive oxygen species (ROS) function as signaling
molecules in plant development, the molecular mechanism by which ROS regulate plant …

Mitochondria are essential for the eukaryotic cell and are derived from the endosymbiosis of
an α-proteobacterial ancestor. Compared to other eukaryotes, RNA metabolism in plant …

Respiration, an essential metabolic process, provides cells with chemical energy. In
eukaryotes, respiration occurs via the mitochondrial electron transport chain (mETC) …

In the last years, a number of nuclear genes restoring cytoplasmic male sterility (CMS) have
been cloned in various crop species. The majority of these genes have been shown to …

Group II introns are large catalytic RNAs (ribozymes) which are found in bacteria and
organellar genomes of several lower eukaryotes, but are particularly prevalent within the …

Lesion mimic mutants are used to elucidate mechanisms controlling plant responses to
pathogen attacks and environmental stresses. Although dozens of genes had been …

Complex I (NADH: ubiquinone oxidoreductase) is central to cellular NAD+ recycling and
accounts for approximately 40% of mitochondrial ATP production. To understand how …

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