All eukaryotes have mitochondria, right?

In fact no. A few haven't due to secondary loss (an interesting lesson in evolution tree redrawing too, when they realised that).

It took me time, but here are 2 interesting papers:


[url=http://www.scopus.com/scopus/inward/record.url?eid=2-s2.0-0030844640&partner=40&rel=R4.0.0]Germot, A., Philippe, H., Le Guyader, H.
Evidence for loss of mitochondria in microsporidia from a mitochondrial-type HSP70 in Nosema locustae
(1997) Molecular and Biochemical Parasitology 87 (2), pp. 159-168. [/url]

Presence of a mitochondrial-type 70-kDa heat shock protein in Trichomonas vaginalis suggests a very early mitochondrial endosymbiosis in eukaryotes
(1996) Proceedings of the National Academy of Sciences of the United States of America 93 (25), pp. 14614-14617. [/url]

Note that I didn't say it was a frequent event. :)

The second one should be free of charge, either on the publisher site or in Pubmed central. The second one is published by elsevier, an editor famous for not allowing free access to its journals, sorry, I forgot to check for that with my institutional subscription.

I found other references from the same team, but in French so I don't think it will help. Anyway to cut short a long story, at least N. Locustae and T vaginalis are 2 eucaryotes who lost their mitochondria, but retained some of their genes in their genomes as a proff of their former presence.

Thanks for the info Patrick. :)

EDIT: I've found something: T. vaginalis, Entamoeba histolytica, and Giardia lamblia lack of mitochondria.
Here is the site if someone is interested in: http://www.tigr.org/tdb/e2k1/tvg/intro.shtml

By the way, I think the original question is : Do fungi have mitochondria. As those are not fungi, I guess yes, all fungi have. *afraid of Patrick to find a fungi that does not have mitochondria* :lol:

As far as I know all fungi have mitochondria (no reason to be afraid), so the answer to the title is yes. But, it is not true for all eucaryotes as stated in the post...

It's good to hear that there is no exception for fungi. I feel better now, Doctor. ;)
