Tomato Research Made Easier For Scientists

Editorial Posted On February 10, 2022

Tomatoes are one of the most commonly used plants in the process of genetic modification and experimentation. Researchers have been altering them for decades because they have a clear genetic structure so it comes as no surprise that a large number of scientific breakthroughs were made with this plant. However, scientists working at Boyce Thompson Institute managed to speed up the process of gene modification on tomatoes by exactly six weeks, which will make them even more popular for testing.

So how did they manage to do so? Researchers simply stumbled on this discovery while trying to make tomato plants more fertile. The team that was working on this project tried introducing DNA to a tomato in order to create a brand new plant. Auxin which is a hormone that speeds up the growth changed things up and it was responsible for the faster development of this plant. Therefore, the entire process of genetic modification was quicker as well.

Usually, the undertaking lasts for seventeen weeks. The scientists introduce new DNA to the tomato seed by inserting Agrobacterium tumefaciens. The modified cells directly influence the regeneration medium that is in charge of nutrients which are needed for a healthy development of a brand new plant xnxx. The modified plant is kept away from the soil for some time in order to grow roots. They are planted as soon as they are ready.

The new method shortens the length of the rooting process, completing the whole procedure in just eleven weeks. So why is this new approach useful for the researchers? Having in mind that tomato is frequently used for genetic modification, scientists will be able to closely monitor the growth of the plant and observe the changes that happen on both inside and the outside. Additionally, it will reduce the costs of the experiments, save time, and allow them to work on several projects at once.

Also, researchers will be able to test various other modifications and apply them to numerous plants that can solve various global problems, including the widespread of hunger and poverty in the third world countries. We are all aware of the issues that people in those countries face on a daily basis, and having a better understanding of the food production can revolutionize the agriculture all over the globe. There will be no need for financial aid from the developed countries once the steady production begins.

Understanding the DNA of a certain crop is the major step forward in creating crops that can survive harsh environment, and tomatoes are one of the best plants to use for analysis. Speeding up the development process will let scientists have more finances to fund other projects that might upgrade and enhance the food production in the future and ultimately provide us with a complete understanding of the GMO and the way they work. This finding will surely speed up the research that is currently underway at Boyce Thompson Institute and we can expect great things from the scientists that are working there.

Sugar Beets- The Cautionary Tale of GMO Acceptance

Editorial Posted On May 6, 2016

Sugar beets seem to be an innocuous crop, not spoken of as much as other modified plants. However, the story of the rise and fall of the modified sugar beet gives a possible outlook to how the mass adoption of genetically modified foods can backfire when the public perceptions and political forces change to go against such adoptions.

According to the Reuters article “GMO backlash threatens beet farmers as foodmakers swap sugars”, the problem occurred when all American beet growers, located in agrarian states like Michigan, North Dakota, and Idaho, had all switched their crop production to genetically modified variants. The farmers had done this in an effort to stay competitive in the world sugar marketplace where importation of sugars such as cane sugar had begun to eat into American market share. The hope was that the genetically modified various would benefit farmers two-fold, giving American producers an increased yield as well as a decreased cost in maintaining the seed and growth. Uniquely among any other farming segment in America, while there is contention between growers and their switch from all natural to gmo crops (and the unintentional spread of gmo seeds during pollination to non-gmo farms), the seeming success of the beet crop had a 100% conversion rate. Soon all American beet farmers were growing only the genetically modified versions of the crop.

However, this success couldn’t last forever. Eventually the sentiments against the gmo community grew to a fever pitch and both consumers and distributors stopped buying the modified crop. With this boycott also came the rising imports of cane sugar from abroad. These two factors led to disastrous result for the beet growing community- the U.S. of beets in satisfying the sugar demands of the American public fell to just 41%, the Reuters article reported, which was a record low.

One of the biggest economic blows that effects gmo growers is when large, established businesses refuse to use the modified ingredients in their products. Beet producers felt the sting of this type of decision when the Hershey Corporation announced that it would stop using the modified sugar crops in the production of its popular chocolates. Hershey announced this move was to better connect with the target market of health conscious millennials. But what are they afraid of?

Again, the article gives some clues. It states that some of the biggest worries regarding genetically modified plants was whether the use of gmo seed has led to a greater industrialization of the farming sector, where it has becoming harder for mom and pop farms to keep operating amongst billion dollar companies. While the loss of one of the oldest types of American dream is hard to deal with, the other problem is that many contend that there isn’t enough research yet to prove that genetically modified crops are safe for the ecosystem or consumption. Both arguments are ones that are used often in the controversy surrounding the gmo movement, and there are voices on both sides.

But the modified beet farmers are holding tough, because many can’t afford to go back to non-altered seed given the investment they’ve already made into the modified variety. So instead they are trying numerous efforts, from lobbying the government and surviving off of federal quota systems that pay the difference of a shortfall crop year to social media campaigns where they are trying to promote the idea of using beet sugar as beneficial to the modern consumer. In an uncertain economy, beet growers are doing all they can to keep their genetically modified businesses running.

Examining Inborn Defenses against Pests in Leptra Corn

Editorial Posted On May 5, 2016

One of the most prevalent traits of genetically modified plants is their ability to resist insects that would normally consume and destroy the plant. One recent addition to the family of gmo plants created to protect itself from insects is a hybrid plant created by DuPont Pioneer and is known as Optimum Leptra. The website states that the modification is to the corn plant and is designed to reduce the ear feeding of lepidopteran pests which delivers cleaner ears with less kernel damage and that it eliminates the major risk of development of molds and mycotoxins in harvested grain (“Optimum Leptra Hybrids”).

An article by Clarin Rural, covering news in the Latin American regions, talked about how the corn will soon be introduced in Argentina after having the Ministry of Agro Industry approve the marketing of the plant (“Resistant corn comes with four transgenic events”). The article gives more details on the function of the modifications, stating that two of the events protect against stem borer and isoca Tang, a double event for protection against fall armyworm and glufosinate ammonium with a room for glyphosate. The corn has already been made available in Brazil and hopes carry to better yields with it in Argentina.

In the United States the protections on the crop protect it from different pests. In the article “DuPont Pioneer releases Optimum Leptra Hybrid” on AGProfessional, in the United States the insects repelled by the modifications of the corn include European and Southwestern corn borers, the corn earworm, and black and western bean cutworms. In the article, penned by the DuPont Pioneer Company, they cite figures of 98% reduction in ear feeding damage using their crops. The plants are also resistant to herbicides, protecting them from more types of poison control.

Some of the traits found in the corn have long been used in other genetically modified plants produced by DuPont, and have long known mechanisms for working. For example, Herculex I, a trait available in Leptra to kill bugs functions by being ingested by larva who feed on the modified plant. The protein binds to receptors in the gut of the larva and causing a series of reactions which ultimately lead to the death of the larva (“Herculex FAQ”).

As with any genetically modified food, of course, there are questions about the effects these different traits may have on the ecology around it. Modified plants that have natural pesticides and that are resistant to herbicides and pesticides have been shown to cause resistant strains of weeds and pest insects to survive and reproduce, causing a drop in the effectiveness of the traits modified in the plants. The article “How pesticides develop” by Michigan State University explained that worldwide more than 500 species of pests have developed a resistance to pesticides due to the growth of resistance among their populations.

Even so, the Clarin Rural article goes on to state that the importance of the Leptra crop is that, since it has so many different resistance traits it makes it easier to rotate the amount of herbicides and pesticides needed for cultivating the crop. In addition, the natural pest defenses the corn has should also reduce the amount of poison needed as it is targets the greatest pests that threaten the growth of corn plants in the regions the crop is planted in. All of these different additions may prove to be fundamental in helping feed a world that is highly defendant on its corn plants on production, if they can get past the stigma of genetic modification and scientific uncertainty.

Revisiting the Usefulness of Aesthetic Genetic Modifications with Innate Potatoes

Editorial Posted On May 4, 2016

Innate potatoes, developed by the agency J.R. Simplot, are the first genetically modified potatoes to be approved by the FDA for consumption. The potatoes have a wide verity of inserted genes added for the benefit of the crop, the farmers growing them, and consumers who purchase them. In the article “What Varieties of Potato are GMO?” on Livestrong, it is reported that the potatoes come in three different varieties- Ranger Russett, Russett Burbank, and Atlantic. Also in the report it was listed that, in their March 2015 press release about their evaluation of the crop and decision that the potatoes passed criteria such as toxicity, potential for allergic reaction, stability of unintended side effect, and more.

The main benefit that is highlighted in media coverage of the Innate potatoes are the same benefits that Arctic Apples were designed to have- a resistance to unattractive bruising and brown spotting on the inside. NPR goes into further detail in “GMO Potatoes Have Arrived. But Will Anyone Buy Them?”, explaining that the reason the agency named the potatoes “Innate” was because the genes used to silence the reaction in the spuds that caused the browning are actual native to potatoes themselves, but that they went unused after a while. Much of the food waste in the world comes from the distribution process, either when processers discard unattractive foods or when consumers at home discard their bruised fruits and vegetables before eating them. The hope is that this process keeps potatoes looking more healthy and attractive so that less will be wasted in the trash.

Another potent benefit of the modified potato, as mentioned in the NPR article, is that the Innate potatoes contain much less of a chemical known as acrylamide, which is triggered in the frying process. Studies on lab rates have shown that consumption of acrylamide increases the potential of cancer in lab rats, a litmus test often showing parallels in humans.

There are a host of other benefits, explains the article “Genetically Modified Potatoes Are Making Their Way to the Produce Section” from Fortune. The potatoes are designed to resist the blight that led to the Irish Potato famine, an inserted gene from another species located in Argentina that grew to resist such pathogens. This kind of blight protection is handy for farmers, as it allows the plant to protect itself from the most common diseases they would have to look out for. The potato is also designed to be able to be stored for a longer period of time at lower temperatures, allowing them to be kept in stores and sold over a greater duration. This is also hoped to reduce the spoils of food waste on the distribution side.

Although there are a great number of seeming benefits to the use of these potatoes, Simplot agency faces the same problems as do the other producers of genetically modified plants- there is still a heavily negative perception of such crops and a reluctance to adopt their use. Big retailers such as the McDonalds Corporation (who has worked with Simplot for many, many years), Frito-Lay, and ConAgra foods have all publically stated they will not use the modified plants. Even with a successful FDA evaluation of the crop, Simplot will have to do more on its end to prove to consumers that their new potatoes are worthy of interest and will do more good for public health than bad. This will be an important obstacle to overcome to a huge market as potatoes are reportedly the third most consumed food crop in the world, according to the International Potato Center.
