Mitochondrial genes on the move
Article Abstract:
Mitochondria are organelles that generate energy in cells. Researchers have found that an evolutionary rapid transportation system has frequently helped to tranfer genes from mitochondria to the cell's nucleus in flowering plants.

An ancestral mitochondrial DNA resembling a eubacterial genome in miniature
Article Abstract:
Mitochondria have evolved from endosymbionts with eubacterial-like form. Mitochondrial genomes have marked variations in structure making it impossible to determine the initial form of the proto-mitochondrial genome. A primitive mitochondrial genome in Reclinomonas americana, a freshwater protozoon, is described, displaying ultrastructural characteristics linking it to the retortamonads. It provides an example of a minimally derived mitochondrial genome, giving new insights in to gene content.

Rickettsia, typhus and the mitochondrial connection
Article Abstract:
Andersson and colleagues have reported the entire genome sequence of Rickettsia prowazekii which causes louse-borne typhus. R. prowazekii can only live in other cells and it has been discovered that its genome encodes 834 complete open reading frames. The Rickettsia and mitochondria DNAs are good examples of highly derived genomes, with the R. prowazekii genome containing genes encoding components of the tricarboxylic acid cycle.
