Alberto, Sure, this would be interesting. You have mentionned GM soy engineered for roundup. Have you ever heard about any GMO which seeds would get activated by roundup ? In the case of Cardamine hirsuta, the seed is so tiny that it may be more exposed to environemental chemicals than bigger seeds ? But if such GMOs do exist, one will need to understand if it was possible that Cardamine got polluted by the roundup genes ? If it is not genetic pollution, then what is it ? Has anyone ever observed this phenomenon somewhere else or is it my local strain of Cardamine only, and I'm so lucky ? *Dr. Christian M.
