Cardamine hirsuta

Dear all,

I would like to ask your advise about Cardamine hirsuta.

Few gardener friends and I have noticed that roundup herbicide activates
the seeds of Cardamine hirsuta, that are asleep in the soil (by the way, I
ignore how long the seeds of this plant survive asleep).

In areas that were free of Cardamine the previous years, treated with
roundup during the summer, a dense population of this plant is sure to be
found next spring. However, this burst has nothing to do with cleanness of
the area after herbicide application, because other places manually weeded
will never exhibit the phenomenon. Roundup application and Cardamine
infestation is so highly correlated that people here use to say that
roundup "makes it come".

I know that there has been some cases of genetic pollution from GMO into
wild species through pollen. I ignore if some GMOs requiring roundup to get
their seeds activated do exist ? If yes, wouldn't this example be one such
case of genetic pollution accident ? Have people observed this phenomenon
elsewhere in the world ?

It is worth asking the question since some people eat Cardamine hirsuta and
advertise it as delicious. However, if it had been turned accidentally into
a wild GMO requiring roundup to wake up and grow, would it be that safe for
human health ?

Any comments, ideas, and tracks will be much appreciated - Many thanks.
