Drift of herbicides beyond field boundaries may function as a selective agent contributing to increased persistence of escaped transgenes in the environment. Londo et al. examine the effects on Brassica napus–B. rapa hybrids of drift of glyphosate (0.1× field application rate) and find that a single dose increases the reproductive fitness of hybrids relative to non-transgenic genotypes and alters gene flow within the experimental communities.
The sympatric presence of transgenic crops with their wild relatives is an ecological concern. Liu et al. conducted a field experiment using insect enclosures with and without herbivores with cultivated Bt-transgenic...
How fast do transgenes move from crops into wild relatives via gene flow?
The contentious matter of plant GM (genetic manipulation – which always sounds more menacing and mankind-meddling-with-nature than GE, genetic engineering, or the other GM – genetic modification…) has been...
