Right, but even in vertebrates there are documented gene transfer events:
Numerous examples of mitochondrial pseudogenes have been documented in the
nucleus of humans (e.g., Hazkani-Covo et al., 2003; Mourier et al.,
2002; Woischnik and Moraes, 2002) and other animals (reviewed in
Bensasson et al., 2001).

And since plants and amoeba have a mitochondrial genetic code that is
the same as nuclear genetic code, probably the ancestral condition was
that both was the same. So the problem of gene transfer between that
organelle to nucleous (and vice-versa) probably was not impaired by
this.

Remember that we was talking about lateral gene transfer at *origin*
of the LUCA or cenascestor.
