Ronald Goldy - December 20,All organisms translate DNA the same way, making it possible for any organism to read DNA from even unrelated organisms. There is much confusion surrounding the how, why and what of genetically modified GM crops, which are crops developed using genetic engineering technology. Some articles may lead one to believe GM crops somehow produce their own weed or insect control chemicals, and by consuming any part or product from that plant, the consumer is eating a dangerous chemical. This is not the case. It is true some GM plants have added protection from a new trait, but FDA regulations require modified plants to not be harmful to humans.

Genetically Modified Food and the Second Green Revolution

While selective breeding has existed for thousands of years, modern biotechnology is more efficient and effective because seed developers are able to directly modify the genome of the crop.Plants that are genetically engineered GE have been selectively bred and enhanced with genes to withstand common problems that confront farmers. These include strains of wheat that are more resistant to drought, maize that can survive pesticides, and cassava that is biofortified with additional nutrients.

In addition to resistance-based attributes and biofortification, some GM crops can produce higher yields from the same planted area. GM crops have the potential to strengthen farming and food security by granting more certainty against the unpredictable factors of nature. These resistances and higher yields hold great promise for the developing world and for global food security. Yet, controversy remains over access to this biotechnology, corporation patents on certain plant strains, and claims regarding the safety and quality of GM foods as compared to non-GM foods.

Genetic modification can protect crops against threats to strong yields, such as diseases, drought, pests, and herbicides used to control weeds, and therefore improve the efficiency of food production. While farmers have been selectively breeding plants for centuries, genetic engineering allows new traits to be developed much more quickly. Utilizing traditional selective breeding can take multiple growing seasons to develop and test a new variety.

Genetic engineering is more precise than conventional hybridization and therefore is less likely to produce unexpected results.

For example, mutagenic breeding is not considered genetic engineering yet it exposes plant material to radiation or chemicals to create varieties with new traits. GMOs seem to be in the news a lot lately. Is the GMO process new? GMOs are in the news a lot right now, but not because they are new. They have actually been in our food supply for nearly 20 years. Farmers have been using hybridization and mutation breeding of crops to improve their resistance to pests or environmental conditions for decades.

In order to feed a world population that is expected to top 9 billion by and to do so in ways that do not harm the environment, farmers will need to roughly double current production levels on about the same amount of land. Genetically modified crops are more efficient and therefore use less agricultural inputs to produce the same amount of food.

From , without GM crops the world would have needed million more hectares of land for equal crop production. Genetic engineering can therefore help to ameliorate the effects of agriculture on the environment. Farming accounted for 24 percent of global greenhouse gas emissions in and 70 percent of freshwater use. GM crops also allow for greater use of no-till cultivation, which helps with carbon sequestration, soil erosion prevention, and better soil fertility.

Genetic modification can improve the nutritional profile of food and therefore serves as a key element in reducing global rates of malnutrition. For instance, golden rice is enhanced with beta-carotene and therefore provides a dose of vitamin A, a nutrient lacking in many diets around the world. Vitamin A deficiency leads to the death of nearly , children each year, so golden rice is a crucial initiative in reducing malnutrition. Another study in India showed that each hectare of Bt cotton increased caloric intake by 74 calories per person per day and that 7.

Why use genetic engineering if other methods are just as effective at boosting productivity? Genetic engineering research has focused on overcoming problems that affect productivity, such as disease, weeds, and pests.

When crops can avoid disease, weeds, and pests, crop yield is enhanced. Genetic modification is only one of the tools that farmers can use to boost productivity, and it does not eliminate the need for other advances such as hybridization, agricultural chemicals, and farm machinery.Rather, genetic modification is a technologically advanced application of biotechnology that works in conjunction with other modern agricultural practices. Are there examples of how genetic engineering has been able to strengthen plants in order to help them survive?

In the early s, papayas in Hawaii were hit with Papaya Ring Spot Virus, devastating the crop with a 40 percent reduction in just five years. Scientists developed two varieties of papaya that were resistant to the virus, and today healthy papayas are now growing in Hawaii.

How widely are GE seeds being accepted and used by farmers across the globe? These statistics tell the story of the level of acceptance and use of GE seeds by farmers of plots large and small, in both the developed and developing world. According to the independent International Service for the Acquisition of Agri-biotech Applications ISAAA , a not-for-profit organization, the global area of biotech crops for wasWith both an increased cost to the farmer and the largest focus of GE crops mainly on staple crops, is the opportunity for using GE mostly limited to farmers in developed countries?

How does the use of GM technology affect smallholder farmers in developing countries? Genetic modification helps to eliminate some of the problems faced by smallholder farmers, such as droughts, pests, and crop disease.

In , over 16 million smallholders in developing countries grew biotech crops. Fifteen million smallholder farmers in Burkina Faso, China, India, Pakistan, and a few other developing countries grow Bt cotton. In countries with weak or nonexistent extension services, farmers can face challenges in accessing GM seeds and in learning best practice growing techniques.

Some countries ban the importation of seed while others exclude genetically modified seeds.Genetic modification prevents crop loss due to disease, insects, and herbicides used to control weeds, resulting in more efficient production and potentially lower food prices. According to the World Bank, agricultural sector growth is the most effective pathway for reducing poverty and increasing food access. GM crops also reduce insurance costs for farmers by producing more consistent yields.

Why do companies that are selling GE seeds have such tight controls over them? Because of tight government budgets, today much less research is being conducted in the public realm using tax dollars which would facilitate greater public access to that research.

Companies that are in the seed business are taking on the financial and research challenges to develop new seeds themselves. As a result of their substantial investments in time and money, these companies are filing patents on the seeds that they eventually bring to the farmer. The large seed companies, of which most are American, are making investments in research and production of technologies that respond to the global marketplace.

They are less likely to invest in the genetic engineering of indigenous crops that are not globally traded but are nonetheless important locally.

This has led critics to claim that GM will undermine biodiversity. Supporters, on the other hand, believe that GM has many benefits for neglected crops, especially when funded by the public sector. As mentioned above, the papaya crop in Hawaii was being consumed by a virus, and the industry faced failure until the introduction of a transgenic papaya turned it around.

Researchers in Uganda and Kenya are showing positive gains on a wilt that affects bananas, by transferring two genes from green peppers. Other crops that researchers are working on include eggplants, blackeyed peas, and cowpeas.With companies then playing a significant role in developing new GE seeds, what are governments doing, if anything, to regulate these new biotechnologies?

Governments on the national level across the globe are actively reviewing and regulating for approval these new technologies. Each new technology goes through a comprehensive regulatory review that in the United States also includes the opportunity for public comments. In the U. What is the controversy about labeling foods that contain genetically modified ingredients?

There have been a number of state referendums that would require all foods to be labeled if they contain any genetically engineered ingredients. Proponents argue that consumers have the right to know what is in their food. Some studies have found that between percent of food in the United States has some GM ingredients. Without any new state or federal laws, manufacturers of foods that do not contain GM may already label their products as GM-free if they choose. Opponents suggest that this type of label would put a stigma on a farming technology that numerous studies show has no negative health implications.

Additionally, labeling would require the adoption of significant changes in how crops are grown, stored, and processed that would result in increased food prices. Different state rules for labeling would make it difficult for companies to comply. What does the organic label mean and what is its relationship to genetic engineering? Does an organic label mean it is GMO free? The National Organic Program was created by the Department of Agriculture in to regulate organic foods. To obtain the organic certification, synthetic fertilizers and pesticides may not be used, nor can seeds that have been genetically engineered.

Genetically engineered foods

Green genetic engineering comprises a plethora of methods that enable the production of genetically modified i. The number to be introduced can vary from one single gene to several genes. For example, in order to establish a new and foreign metabolic pathway in a particular plant, several genes need to be introduced. The first field trials with transgenic plants were carried out in the USA in and the worldwide cultivation of transgenic plants has increased year on year ever since. Depending on the goal of any particular genetic modification, transgenic plants are divided into first-, second- and third-generation plants.

Green genetic engineering is a highly targeted method to provide plants with new genetic properties. It involves transferring genes or other sections of the.

GM is a technology that involves inserting DNA into the genome of an organism. Usually, the cells are then grown in tissue culture where they develop into plants. The seeds produced by these plants will inherit the new DNA. The characteristics of all living organisms are determined by their genetic makeup and its interaction with the environment.The genetic makeup of an organism is its genome, which in all plants and animals is made of DNA.

Bt-Corn: What It Is and How It Works

A new technique has the potential to change the foods we eat every day, boosting flavor, disease resistance, and yields, and even tackling allergens like gluten—and scientists say they're working only with nature's own tools. Under a blistering July sun, Zachary Lippman bends over a row of foot-high plum tomato plants to reveal budding yellow flowers that will each produce a tomato and ripen over the summer. Out here, on the grounds of a former dairy farm, it has all the appearance of age-old tradition. He created the plants using gene editing, a technology—based on a natural process —that allows researchers to cut out certain bits of DNA in order to control traits.

Pamela Ronald is a plant scientist, married to an organic farmer.

How to Make a GMO

Bt-corn is a type of genetically modified organism, termed GMO. A GMO is a plant or animal that has been genetically modified through the addition of a small amount of genetic material from other organisms through molecular techniques. Currently, the GMOs on the market today have been given genetic traits to provide protection from pests, tolerance to pesticides, or improve its quality. Genetically modified foods are foods derived from GMO crops. For example, corn produced through biotechnology is being used in many familiar foods, including corn meal and tortilla chips.

7.23B: Applications of Genetic Engineering

In recent years, public attention and controversy have blossomed regarding the use and production of genetically modified organisms GMO's and other biotechnologies used as agricultural inputs or produced as outputs. Two widely used examples of genetically modified organisms used as agricultural inputs are RoundupTM tolerant corn, soybeans, canola, and cotton and other plants that carry a gene from the bacteria Bacillus thuringiensis Bt.The Bt gene allows plants including corn and cotton to produce its own insecticide. The purpose of this paper is to explore the implications of GMO and other biotechnology and genetic engineering applications in production agriculture on the health and safety of workers. Nor is it the intent of this paper to explore environmental health implications in great detail, although there are implications related to changing products and practices such as pesticide use and toxicity, tillage practices and water quality implications , pest resistance, and transfer of genes to other species Cook, ; Wolfenbarger,

There are many benefits to using genetic engineering. It is used in agriculture to do things such as, improve the yields. of important economic crops, and.

Is green genetic engineering sustainable?

Genetic engineering is the process of using recombinant DNA rDNA technology to alter the genetic makeup of an organism. Traditionally, humans have manipulated genomes indirectly by controlling breeding and selecting offspring with desired traits. Genetic engineering involves the direct manipulation of one or more genes. Most often, a gene from another species is added to an organism's genome to give it a desired phenotype.

The genetic modification of food is heavily politicised and there are numerous arguments for and against the practice.Proponents of genetically modified GM food claim that it will increase food security, primarily by making agriculture more efficient, while detractors argue that the technology is potentially dangerous and the cultivation of GM food could have unforeseen consequences that will ultimately prove detrimental to food security. By examining the use of GM in plant and livestock agriculture, this paper will consider both sides of the debate. Ultimately, some varieties of GM food have the potential to strengthen global food security while others are likely to be self-defeating in the long-term. Genetic engineering, which involves the modification of the genetic makeup of living organisms, has been practiced for over 40 years and commercial applications have been available for the last two decades. Biotechnology, of which genetic engineering is a part, is a relatively young field and it is yet to reach its full potential. Equally, however, the possibility of unintended or unforeseen problems arising from the technology remains and it would be irresponsible to rush into the widespread production of GM food without first testing the safety of each product.

By ‘Editing’ Plant Genes, Companies Avoid Regulation

Over the last 50 years, the field of genetic engineering has developed rapidly due to the greater understanding of deoxyribonucleic acid DNA as the chemical double helix code from which genes are made. Developing plant varieties expressing good agronomic characteristics is the ultimate goal of plant breeders. With conventional plant breeding, however, there is little or no guarantee of obtaining any particular gene combination from the millions of crosses generated.
