With enough time that trait would show up by simple selective breeding too. GMO does it faster. (Of course so much faster that there is an argument that it's qualitatively not the same as good old breeding. And if someone comes up with some kind of killer trees that release anthrax in the spring that too counts as GMO too, but they are unlikely to be deterred by labeling requirements or GMO bans.)
