RNA metabolism in plant mitochondria
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 …

Insights into the Evolution of Mitochondrial Genome Size from Complete Sequences of Citrullus lanatus and Cucurbita pepo (Cucurbitaceae)
The mitochondrial genomes of seed plants are unusually large and vary in size by at least
an order of magnitude. Much of this variation occurs within a single family, the …

Sorting of mitochondrial and plastid heteroplasmy in Arabidopsis is extremely rapid and depends on MSH1 activity
The fate of new mitochondrial and plastid mutations depends on their ability to persist and
spread among the numerous organellar genome copies within a cell (heteroplasmy). The …

PRORP proteins support RNase P activity in both organelles and the nucleus in Arabidopsis
RNase P is an essential enzyme that cleaves the 5′ leader sequence of tRNA precursors.
RNase Ps were believed until now to occur universally as ribonucleoproteins in organisms …

Phage-Type RNA Polymerase RPOTmp Performs Gene-Specific Transcription in Mitochondria of Arabidopsis thaliana
Transcription of mitochondrial genes in animals, fungi, and plants relies on the activity of
T3/T7 phage-type RNA polymerases. Two such enzymes, RPOTm and RPOTmp, are …

The reverse transcriptase/RNA maturase protein MatR is required for the splicing of various group II introns in Brassicaceae mitochondria
Group II introns are large catalytic RNAs that are ancestrally related to nuclear spliceosomal
introns. Sequences corresponding to group II RNAs are found in many prokaryotes and are …
