Wasnt tbis site covered here before btw, as I remember the findings werent too good, infact you have no guarantee your plant will glow noticably, I believe.
Seems like they are now aiming for more iterations zo really make it glow...
As expected: Still not doing as desired

And in complex organisms it again is a more difficult endeavor than for example in bacteria.
More thoughts on wether or not to fancy GMOs:
Maybe the differenciation "traditional method" vs "genetic engineering" doesnt help at all. Personally I'd at least differentiate traditional methods as follows:
Mutagen free methods (here again inter and intra species) and methods involving mutagenes.
I'd differenciate genetic engineering as follows:
Cis- and transgenic.
In the end, like everyone, I value a real breeding effort the most, if its limited to one species and achieved by pollinating, sowing, selecting ... or any real ancient method that mimics biology.
After that comes cisgenic GMO.
And artificial mutants and transgenic GMO cause me to feel equally uneasy. I cant really tell which I'd prefer.
