Thanks, I think my claim was a bit sloppy and underspecified there. The typical anti-GMO concern that I was addressing is that a gene, once introduced, could spread into any plant in the ecosystem and into the weeds that compete with farmed plants, i.e. beyond the species with which the organism can pollinate. The paper you linked shows: > that a weedy form of the common rice crop, Oryza sativa, gets a significant fitness boost from glyphosate resistance which I believe is a much narrower claim. If the anti-GMO claim was that "GMO crops can share their genes with wild/weedy/non-GMO versions of those crops", I don't think anyone would be freaking out in the same way. But my specific claim was about gene transfer to unrelated species, which (to my understanding) is not likely. (There's also horizontal gene transfer to worry about, but this is very unlikely in eukaryotes, e.g. see https://www.ebr-journal.org/articles/ebr/pdf/2008/03/ebr0742.pdf https://www.ebr-journal.org/articles/ebr/pdf/2008/03/ebr0742...)
