Here is a question for AbBioView readers. Is there DNA evidence that the
plant genome contains foreign DNA? I can think of retrotransposons which
may by their movement activate endogenous genes and certainly this is
happening as an integral part of evolution. There is of course the DNA of
ancient endosymbionts, some of which is now in the nucleus. Are there
other examples for the incorporation of DNA other than in pahogenicity
I probably should know the answer to this, but I cannot think of examples.
