Vergelijking tussen verschillende plantveredelingsmethoden

Schematisch overzicht (klik voor grote versie) die verschillende plant veredelingsmethoden met elkaar vergelijkt. De lijst is wel opgemaakt vanuit Amerikaans oogpunt en de lijn die patentering behandelt, geldt dus enkel in Amerika. Daar kunnen klassiek veredelde gewassen namelijk ook gepatenteerd worden.

Physicians Answer Questions About Food Biotechnology

Technologies, such as food biotechnology, have become an important part of agriculture. However, many myths and misperceptions about food biotechnology have led to questions about its safety and benefits for the public. The video segments below were developed to help clarify the facts on food produced through biotechnology and to address some of your most common questions. In the videos, physicians who are leaders in their field discuss the following topics as they relate to food biotechnology: Safety; Allergies; Children; Benefits; and Labeling. These physicians have relevant background in these areas, as well as knowledge of the safety and health research around food biotechnology.

Is there a link between foods produced through biotechnology and allergies?

Hawaii’s Biotech Papayas Hold a Lesson for America

A new supply of fresh papayas from Hawaii will reach grocery-store shelves in Japan this year and consumers have biotechnology to thank for it.

The first “Rainbow” papayas–genetically modified to withstand the deadly ringspot virus—are now on sale. They are the first GM food Japan has approved for commercial release.

It represents an important step for a country that has resisted a technology that is now conventional in North and South America and increasingly common in Africa and Asia.

The story of how cutting-edge agriculture defeated disease and saved Hawaiian papayas shows that we have much to gain from GM crops, even as professional protestors peddle scientific ignorance to frighten the public about this essential food source. The rest of the United States may want to pay attention, as voters in California and legislators in more than a dozen states consider burdensome food-labeling laws.

In the middle of the 20th century, as Hawaiian papaya farmers started to enjoy commercial success, the ringspot virus appeared almost out of nowhere to threaten our livelihood. For a while, we were able to contain its spread by destroying infected papaya trees. Yet this was a drastic remedy. One year, I had to cut down half my orchard.

By the 1990s, however, it was almost pointless for Hawaiian farmers to raise papayas. The risk of crop failure was too high. I stopped growing the fruit and so did most of my neighbors.

Meanwhile, scientists worked on the problem. Dennis Gonsalves, then of Cornell University, learned how to take a piece of the ringspot virus and use it to “inoculate” trees, much as vaccines can improve immunity against diseases in people. In 1998, we started to sell GM papayas, which are just as healthy and delicious as the ones they replaced.

This simple innovation saved Hawaiian papayas. The ringspot virus is still out there, ready to wreak havoc–but it won’t infect any of the trees that descend from the innovation of Gonsalves.

Spinach genes beef up citrus trees’ resistance to greening

Spinach, that same green leafy vegetable used by Popeye to pump up also may help citrus trees resist greening disease, or huanglongbing.

Erik Mirkov, a Texas AgriLife Research plant pathologist in Weslaco has transferred two genes from spinach into citrus, apparently imparting greening resistance, according to a news release.

Words Matter: Biotechnology Does Not Contaminate

There is absolutely no reason to treat pollen from biotech seeds differently than from non-biotech.  Biotech crops are the most intensely studied and regulated crops on the planet.  They have been planted on billions of acres over the last 15 years with no credible health concerns.  The technology is good for the environment because it allow farmers to produce more yield with less inputs. Even organic growers are not harmed by the proximity of biotech crops.  If a farmer follows the rules specified by the USDA for organic production the presence of biotechnology in their harvest does not disqualify their organic certification. Under these circumstances, how can biotechnology be considered a contaminant?

The vast majority of the corn and soybeans grown in the United States are genetically modified to fight pests and weeds. Treating these crops as “contaminants” is part of an ideological struggle to prevent farmers from using 21st-century technology. The U.S. Department of Agriculture should speak out, defend the farmers who produce safe food, and refuse to let the professional protestors define the terms of debate.

Transgenic potato resistant to virus

Argentine scientists have developed a genetically modified potato, resistant to potato virus Y (PVY). PVY infections can be devastating, reducing crop yields by 30 to 80 per cent in the most severe cases. The virus causes mottling discoloration of the leaves, affecting photosynthesis which leads to plant stunting. In severe cases, potatoes display a black ringspot on their peel (tuber necrosis) that renders them unmarketable.

The Impact of Genetically Engineered Crops on Farm Sustainability in the United States

Corn, cotton, and soybean that have been engineered to resist insect pests and herbicides are now planted on almost half of all U.S. cropland. An analysis of the U.S. experience with genetically engineered crops shows that they offer substantial net environmental and economic benefits compared to conventional crops; however, these benefits have not been universal, some may decline over time, and potential benefits and risks may become morenumerous as the technology is applied to more crops. Understanding the impacts of geneti- cally engineered crops is vital to ensuring that crop-management practices and future research and development efforts realize the full potential of genetic engineering for commercial as well as public goods purposes, while maintaining the environmental, economic, and social sustainability of U.S. farms.

Makers of genetically modified seeds say more farmers evading EPA rules

Monsanto Co. and other seedmakers reported a threefold increase last year in U.S. farmers caught violating rules intended to stop insects from developing resistance to genetically modified corn.

The rules affect farmers planting seeds modified to produce a toxin derived from Bacillus thuringiensis, or Bt, a natural insecticide. The Environmental Protection Agency requires those growers to also plant an adjacent area — a so-called refuge — of non-Bt corn so that bugs feed on both types of corn and don’t become immune to the toxin.

Een landbouwer aan het woord over het contract met “evil” Monsanto

Volgens tegenstanders van ggo’s moeten boeren die GG zaad kopen een contract ondertekenen dat dicteert hoe hun gewas gekweekt wordt – welke chemische middelen ze moeten kopen – en wordt het hen verboden om zaad aan de kant te leggen. Dit heeft bedrijven volgens hen een enorme controle over de productie van het belangrijkste stapelvoedsel.
