Genetic Engineering in Agriculture Essay

Genetic modified organisms, or GMOs, are living organisms that, through the genetic engineering process, have been altered to withstand certain chemicals and increase the nutritional value of the product. In fact, the majority of the foods found at the grocery store are genetically altered. Genetic modification is becoming increasingly popular on farms throughout the United States and moving into other parts of the world due to their increasing yield capabilities and pest and weed control. However, this has been, and continues to be, an extremely controversial topic of discussion in the world of agriculture and biotechnology, as well as health food critics, because of potential environmental and health risks.

Secondly, increased shelf life of genetically modified foods will enable it to be shipped to distant locations and cut costs as well as minimize waste to consumers. These foods are modified to be pesticide and herbicide tolerant, resulting in less use of chemical sprays; reducing soil contamination and pollution. In addition, genetically modified crops are more resilient, weather tolerant and capable of surviving in adverse climates such as droughts and extremely cold weather (Whitman, 2000).

Humans have been altering the genetic makeup of plants for millennia, keeping seeds from the best crops and planting them in following years, breeding and crossbreeding varieties to make them taste sweeter, grow bigger, last longer. In this way we've transformed the wild tomato, Lycopersicon, from a fruit the size of a marble to today's giant, juicy beefsteaks. From a weedy plant called teosinte with an "ear" barely an inch long has come our foot-long (0.3-meter-long) ears of sweet white and yellow corn. In just the past few decades plant breeders have used traditional techniques to produce varieties of wheat and rice plants with higher grain yields. They have also created hundreds of new crop variants using irradiation and mutagenic

The World Health Organization (WHO) defines genetically modified foods as: “foods [that are] derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism” (WHO, year). GM foods are constructed and distributed because there is some perceived advantage either to the producer or consumer. For a GM food to be of theoretical benefit to the consumer and society as a whole, it should: increase crop yields due to the introduced resistance to pests and disease, enhance the nutritional

Genetically modified crops are an incredibly important issue that everyone should be aware of since it is something we are exposed to at a daily basis. Genetically modified crops also known as GM crops or Biotech crops has been one of the most heated debates of issues within our society. The debate about the safety, concerns and disadvantages of GM crops have raged since the mid 1990 's but this is due to the lack of knowledge of the general public. Many people are unaware of what the GM crops actually are and what they offer. Genetically modified crops are plants that are used in the agriculture and have been modified to initiate a new trait to plants that does not happen naturally in the species. These plants are modified using genetic engineering techniques to enhance desired traits. GM crops are made when genes of commercial interest are transferred from one organism to another.() There are many methods used for the production of GM crops but the two primary used for plant insertion are gene guns and agrobacterium tumefaciens. There are also three types of modifications which are transgenic, cisgenic, and subgenic plants. However, there are a number of issues that surround this controversial topic such as environmental, health, and economic concerns. Even though there are some worrying facts about GM crops people don 't realize the advantages or the ways it has helped humans as well as animals. There are many reasons why GM crops are proven

The term GM food are most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques. These plants have been modified in the laboratory to enhance desired traits such as increased resistance to herbicides or improved nutritional content. Genetically modified plants have been widely publicised as the future in agriculture. Many believe that it may help improve crop harvests and farm productivity by developing genetically modified crops that can either resist pests or chemicals. But despite the promise that GM crops may offer, there are still doubts that linger among a number of people as well.

The governments and scientists were hoping that the GMO’s will provide to the public such benefits as increased food supply, helping underfed nations, assisting farmers, and better overall food taste. Because the crops are already resistant, this would allow farmers to skip steps in the production process, like spraying herbicides and pesticides.

Because there is such an abundance of food in this country (the USA), one can find GMOs almost everywhere, from a cob of corn in the produce aisle to a fast-food quarter pounder. Consequently, if a person is concerned about what food they are putting into their mouth, the topic is GMOs is likely to show up at some point. Growing crops that have been changed on a genetic level to achieve a specific characteristic is now a commonplace practice by many commercial and non-commercial farmers alike. These enhanced species of plants have a variety of advantages over unmodified species. Genetically modified organisms can benefit farmers and consumers because of their increased durability and

For the last several decades, the world has been plagued by widespread starvation and poverty. Economies are failing in numerous countries, and developing nations struggle to feed their inhabitants. As a result of the world’s mounting overpopulation, food has become scarce and resources are rapidly dwindling. However, modern science has provided a solution: agricultural biotechnology. Genetically engineered crops represent the bright future of agriculture. Crops like cotton, corn, and soybeans can have genes inserted or deleted into their cell membranes; this modification facilitates pest and virus resistance, drought tolerance, and even provides nutritional enhancement. Genetically altered crops produce much higher

By definition, food crops are genetically engineered in order to improve the crop- making it more pest-resistant or healthier.

“70 percent of our corn farmland and 93 percent of soy farmland are planted with crops genetically engineered to resist pests and herbicides and increase crop yields. 60% of all the processed foods in the United States are genetically modified; a shocking statistic has the concern of many Americans. However, most people are uninformed about the beneficial impact that genetically modified food has on their diet. GM is the use of molecular biology technology to modify the inherited structure of organisms. Genetically engineered crops increase nutrients, drought tolerance, provide more food for growing populations, and resists diseases and pesticides. Genetically engineered foods are crucial to the improvement of economy, agriculture, society, and health choices. The creation of GM foods was one of the most significant breakthroughs in food industry. Genetically modifying foods is a key component that is harmless for the enrichment of our foods.

Many people today are often amazed by the amount of nutrition and health information required for humans. The constant stream of genetic modification of food can be confusing. Genetically modified (GM) foods are plants and animals that have had their genetic makeup artificially altered by scientists to make them grow faster, taste better, last longer and to provide more nutrients. Scientists make these alternations by transferring genes from one organism into another in order to change the condition or character of the receiving organism. This process is known as biotechnology or genetic engineering (GE), and it has revolutionized the way that agriculture is practiced in many parts of the world. Researchers are now able to use GE

Instead of transferring large blocks of genes from donor plant to recipient, small isolated blocks of genes are put into the plant chromosome through biolistics, vectors, or protoplast transformation (Horsch 1993). Biolistics is a technique that shoots the gene block into the potential host cell. In order for the process to succeed, the microscopic particles and DNA must enter the cell nuclei and combine with the plant chromosome. Biolistics is commonly used but has a slight failure risk since the breeder has little control over the destination of the gene block (Mooney & Bernardi 1990). Bacteria or viruses can also carry the gene blocks into a new cell. Common vectors in gene transfer between plants are Agrobacterium tumefaciens and Agrobacterium rhizogenes. In the soil, the bacteria will infect the plants with their own plasmid, transferring the desired gene that was placed in the bacteria's DNA. Vector gene transfer is a preferred method of transformation since this modification already occurs naturally in the environment (Rudolph & McIntire 1996). Last is protoplast transformation, which uses enzymes to dissolve the cellulose in the plant wall that leaves a protoplast. Once a specific gene block is added to the protoplast, the cell wall will re-grow into a transgenic plant.

Genetically modified crops are crops that are created using genetic engineering methods i.e. the manipulation of genes in plants and crops to obtain a new generation of crops that have the most desirable traits. The genetic modification of crops comes with both advantages and disadvantages.

GMO foods are not the most healthy or honest foods, but they are the most helpful. Many fruits and vegetables are engineered to be resistant to bugs and diseases that could cause famine. This helps farmers all over the country by giving them a better harvest. Also, non-sanitary soil has become a large problem in some places around the world. The soil made it harder for crops to grow in certain environments. To solve this problem, scientists could take a gene from a plant that can live in these conditions, and plant it into another crop’s genome. This would make the crop that
