Brazil is the second-largest producer of genetically-modified (GM CROPS after the United states. Last year, it farmed 30.3 million hectares of the crops, mostly soya beans,

Many scientists are trying to unravel the complex crop genetics that allows these crops to tolerate environmental extremes,

Schouten argues that his product should not be regulated in the same way as genetically modified (GM CROPS that are engineered with bacterial or VIRAL DNA.
The regulation of GM CROPS in the United states is based on laws that were not tailor-made for the technology.
The Animal and Plant Health Inspection Service (APHIS), the branch of the agriculture department responsible for overseeing GM CROPS,
has stuck so far to a strict interpretation of a 1957 law designed to protect agriculture against plant pests that was coopted in 1986 to regulate GM CROPS.
At that time, GM CROPS were engineered nearly always using Agrobacterium tumefaciens a bacterial pest that can insert DNA into plant genomes.

 The study also challenges the public perception that genetically modified crops carrying extra copies of their own genes are safer than those containing genes from microorganisms."
"Our study shows that this is not necessarily the case, says Lu. The finding calls for a rethinking of future regulation of genetically modified crops,
some researchers say.""Some people are now saying that biosafety regulation can be relaxed because we have a high level of comfort with two decades of genetic engineering,
