Critical Reviews in Plant Sciences, January 1st, 2002
ABSTRACT: The comparison of the mitochondrial genomes in plants shows that the gene complement can slightly vary between individual species. The differentially evolving DNA arrangements and sequences offer unique time windows upon the phylogeny of embryophytes. Genes in plant mitochondria are most often transcribed from their own promoters, many of which conform to a conserved type, probably the point of entry for a nuclear-encoded phage-type RNA polymerase. Primary transcripts undergo various RNA processing steps during maturation, including RNA editing, cis- and trans-intron splicing and 5'-...
