The common theme in all the papers is that the organisms encode chaperonins
(cpn60, cpn10 and/or hsp70) that have clear and specific relatedness to
the mitochondrial isoforms of these proteins. The most parsimonious=20
explanation for this is that they are descended from ancestors that had
mitochondria or harboured the symbiont that gave rise to mitochondria.
Regards,
Graham
