Genetically Modified Organisms Plants Examples
The alteration is done through genetic engineering techniques. Many self-pollinating crops such as wheat barley and potatoes have a low frequency of gene flow but the more promiscuous such as sugar beets and corn merit greater concern.

Some benefits of genetic engineering in agriculture are increased crop yields reduced costs for food or drug production reduced need for pesticides enhanced nutrient composition and food quality resistance to pests.
Genetically modified organisms plants examples. Agricultural plants are one of the most frequently cited examples of genetically modified organisms GMOs. Sugar beet is used to extract and purify sugar and canola is used mostly for edible oil. By genetically modifying crop plants to be tolerant of a commercial herbicide in a way that the weeds are not crops can grow in the presence of powerful herbicides while the weeds are eliminated.
For example rice canola and tomato crops have been genetically modified to increase their tolerance to salt stress. GENETICALLY MODIFIED ORGANISMS 2 A genetically modified organism is any plant or animal with an altered genetic material. The corn alfalfa and soybean crops are nearly all used as livestock feed.
Genetically modified food controversies are disputes over the use of foods and other goods derived from genetically modified crops instead of conventional crops and other uses of genetic engineering in food production. Genetically modified crops engineered to resist herbicides are now more available than conventionally bred resistant varieties. Many people have concerns about using GMOs however more than 2000 studies have found them to be safe.
Tomatoes Tomatoes which are genetically modified which is long lasting and were made available to the consumers as early as 1994. Several salinity tolerance mechanisms have been identified in salt-tolerant crops. An example of genetically modified crops is golden rice.
The following example gives a general idea of the steps it takes to create a GMO plant. For example the application of wide-spectrum insecticides declined in many areas growing plants such as potatoes cotton and corn that were endowed with a gene from the bacterium Bacillus thuringiensis which produces a natural insecticide called Bt toxin. Genetic engineering is the process through which an organisms genes are manipulated by the use of biotechnology so that the organism can suite a predetermined mode.
Genetically engineered crops produce higher yields have a longer shelf life are resistant to diseases and pests and even taste better. The disputes involve consumers farmers biotechnology companies governmental regulators non-governmental organizations and scientists. Next Related Insider Monkey Articles.
The main purpose of producing genetically modified organisms is to increase the yield of crops and produce disease-resistant crops. A final concern of consuming genetically modified organisms is that they may change the genes of both the organism being modified and the consumer. Making a GMO Plant Step by Step.
For example probably the best known herbicide in use is Round-Up glyphospate a product developed by Monsanto. See the rest of the examples of genetically modified organisms GMOs on the following pages. Genetically modified GM crops are plants used in agriculture that have had their DNA modified through gene technology with examples of results such as the following.
Changes in DNA are closely related to cancer and such diseases so fear struck that it would have an effect on the health of those who consume it. As pollen and seeds move in the environment they can transmit genetic traits to nearby crops or wild relatives. In the USA 93 of soybeans and most of.
Today approximately 90 percent of the corn soybeans and sugar beets on the market are GMOs. Some examples of genetically modified organisms or GMOs are corn zucchinis yellow squash and soybeans. The primary purpose of.
As of 1999 the most prevalent GM trait was glyphosate-tolerance. Papayas Papayas are another example which is genetically modified in fighting virus that can possibly kill or infect quickly the crops. After genetic modification it produces twenty times more it-carotene than previous rice varieties.
Page 1 of 5. These benefits are a plus for both farmers and consumers. Golden rice is specifically for use in Asia.
This example uses a type of insect-resistant corn called Bt corn. Corn alfalfa and sugar beet are the major GM crops grown in Colorado but smaller areas of soybeans and canola are also planted. Resistance to certain pests diseases and herbicides tolerance to environmental conditions such as drought or frost increased production of nutrients such as omega 3 oils.
