[Taxacom] Myxozoa (was: surprise from a whole-genome study)

[Jason Mate]

Sorry for the delay. I honestly haven´t kept abreast with Myxozoan phylogenetics (when I studied they were still in ´´Protozoa´´) but they too may be responsible for LGT. I think that as genetic information on metazoans becomes increasingly available we will see more examples of LGT. It would be fascinating (and maybe it is already known outside Bacteria, I don´t know!) if LGT can happen between metazoans via parasitic species (i.e. acquisition and subsequent insertion in another species). If it happened between closely related species it would certainly spice it up. Wolbachia or in mycorrhizal fungi would be organisms to look at in this case. I haven´t read the paper Deborah Lewis kindly provided (thank you by the way) but did the authors mention the kind of fungi they sequenced?

Best

Jason
