#Transgenics next wave of genetically modified crops could ease concerns over Frankenfoods Transgenic canola When the first genetically modified (GM) organisms were being developed for the farm,
who say that transgenic crops have concentrated power and profits in the hands of a few large corporations,

and costs could be higher for other labs. The technique could also assuage a common concern about transgenic crops.
when we create transgenic plants, we insert the transgene somewhere in the genome, and we don't know exactly where it happens to insert,
says Wilhelm Gruissem, a plant biologist at The swiss Federal Institute of technology in Zurich. Now you can target the transgene to a specific location.

Transgenic grass skirts regulators: Nature Newswhen the US Department of agriculture (USDA) announced this month that it did not have the authority to oversee a new variety of genetically modified (GM) Kentucky bluegrass,
With changing technologies, the department says that it lacks the authority to regulate newly created transgenic crops.

when it patented a method for engineering transgenic crops to produce sterile seed, forcing farmers to buy new seed for each planting.
but bypassed the company by purchasing seed for a late-season crop from a grain elevator known to contain Monsanto s transgenic seed.
or a cell culture or a transgenic animal and using it to generate thousands more to sell again at a fraction of the original price."
One tactic would be to switch off the transgene of interest in seeds, so that they could grow into new plants
Another approach is to place the transgene under the control of a switch that must be activated by a proprietary chemical.

Sally  Mackenzie, a plant biologist at the University of Nebraska-Lincoln, contacted APHIS about the high-yield offspring of a transgenic sorghum grass plant
Mackenzie thinks that the transgene triggered an epigenetic change: it altered the plant s gene expression by changing the pattern of chemical groups added to its DNA rather than changing the DNA sequence itself.
