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 …

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 …

Pentatricopeptide repeat (PPR) proteins comprise a large family of helical repeat proteins
that bind RNA and modulate organellar RNA metabolism. The mechanisms underlying the …

Germination represents a rapid transition from dormancy to a high level of metabolic activity.
In-depth transcriptomic profiling at 10 time points in Arabidopsis (Arabidopsis thaliana) …

Mammalian mitochondrial (mt) mRNAs have short poly (A) tails at their 3′ termini that are
post-transcriptionally synthesized by mt poly (A) polymerase (PAP). The polyadenylation of …

We report here on the identification of a novel human nuclear-encoded mitochondrial poly
(A) polymerase. Immunocytochemical experiments confirm that the enzyme indeed localizes …

The mitochondrial NADH dehydrogenase complex (complex I) of the respiratory chain has
several remarkable features in plants:(i) particularly many of its subunits are encoded by the …

Plastids were derived through endosymbiosis from a cyanobacterial ancestor, whose uptake
was followed by massive gene transfer to the nucleus, resulting in the compact size and …

Abstract With CR–RT–PCR as primary approach we mapped the 5′ and 3′ transcript
ends of all mitochondrial protein-coding genes in Arabidopsis thaliana. Almost all transcripts …

Land plant organellar genomes encode a small number of genes, many of which are
essential for respiration and photosynthesis. Organellar gene expression is characterized by …
