It is true that recent systematics studies have suggested that Lycopersicon
should lose its genus status, but to the best of my knowledge, to the best on
my knowledge, the International Code of Botanical Nomenclature (2000 is the
most recent I have-- is there a more recent version?) has not been changed.
Until it is, it will continue to be correctly listed as a genus.

And I doubt that it will be changed, regardless of systematic studies. My
reasons have nothing to do with DNA analysis and everything to do with the
potential economic consequences of the change.
