Hi Andre-Denis,

I'm one of the authors responsible for some of the papers you refer to:

Clark, C.G., Roger, A.J. 1995 Proc. Natl. Acad. Sci. USA 92, 6518-6521

Trichomonas:

Bui, E.T., Bradley, P.J., Johnson, P.J. 1996 Proc. Natl. Acad. Sci. USA 	=

93, 9651-9656

Horner, D.S., Hirt, R.P., Kilvington, S., Lloyd, D., Embley, T.M. 1996 =

Proc. R. Soc. Lond. B Biol. Sci. 263, 1053-1059.

93, 14614-14617

Roger, A.J., Clark, C.G., Doolittle, W.F. 1996 Proc. Natl. Acad. Sci. USA =

Microsporidia:

Germot, A., Philippe, H., Le Guyader, H. 1997 Mol. Biochem. 	Parasitol. =

87, 159-168

Hirt, R.P., Healy, B., Vossbrinck, C.R., Canning, E.U., Embley, T.M. 	=

1997 Curr. Biol. (in press)

Giardia:

Roger, A.J., Svard, S.G., Tovar, J., Clark, C.G., Smith, M.W., Gillin, =

F.D., Sogin, M.L. 1998 Proc. Natl. Acad. Sci. USA (In Press)

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 =

explanation for this is that they are descended from ancestors that had
mitochondria or harboured the symbiont that gave rise to mitochondria.

Regards,

Graham
