Transgenic plants

Transgenic plants plants created by introducing genes from other species through genetic engineering. These systems are usually developed to produce certain desirable characteristics such as resistance to disease, parasites and resistance to herbicides and resistance to certain environmental conditions. To know the transgenic plants and the risks and benefits, read on.

A transgenic organism is the term used to describe a type of genetically modified organism whose genetic material is manipulated to produce changes in the body with the leg you want. To achieve this objective, the genetic material or DNA of an organism is injected in the nucleus of cells play another agency in the same or different, in order to produce or transport suddenly desirable. This technique of creating transgenic organisms is called recombinant DNA. In other words, transgenic organisms are organisms with a single gene or genes transferred from another organism of the same or different species in the laboratory using the technology of recombinant DNA. This technique can be done in both plants and animals to create transgenic plants and animals.

Transgenic plants Appointment

Transgenic plants are plants that are created by introducing genetic material from a different species, using genetic engineering to produce plants with specific characteristics. The genes of different species can be introduced into a plant in several ways. In general, it is easier to produce transgenic plants compared with transgenic animals. In plants, there is no difference between somatic and germ cells and therefore the genes can be introduced into somatic cells and tissues to produce transgenic plants.

In the past, new plant varieties containing genes from two species generated through hybridization or cross. However, the breeding took place between two closely related species. However, modern biotechnology and genetic engineering, integration of genetic material not only connected but also of exotic species to create transgenic plants and genetically modified. Bt corn, Bt cotton and golden rice are just some of the most common examples of transgenic plants created in this way.

Pros and cons of transgenic plants

Production of transgenic plants and the introduction of foreign genetic material is extremely doubtful. A range of benefits and risks of production of these plants have been identified by scientific studies. One of the main advantages of transgenic plants and crops by the introduction of some parts as you want, resistance to diseases, pests and herbicides. This in turn can increase crop yields to meet rising demand for food. Another advantage is that with the help of genetic engineering, it is possible to produce plants that can tolerate adverse environmental conditions such as drought and cold. Even the floor laden with large quantities of salt can be made with the production of genetically modified crops that can grow in saline soils.

All these advantages will ultimately benefit the agricultural sector. With the growing concern about the environmental impacts of using large-scale insecticides and pesticides is very important to reduce the use of these substances. Transgenic plants resistant to pesticides may play an important role in reducing the use of these chemicals. Plant varieties resistant to herbicides can reduce the negative effects of herbicides and the development of transgenic plants resistant to insects can help reduce the total amount of pesticides used. This, in turn, can improve environmental quality. Besides this, some transgenic plants can produce higher levels of nutrients that can improve the nutritional quality of food.

Despite these advantages, the development of genetically modified or altered are widely criticized, particularly by the fact that these plants have a negative impact on the environment, ecosystem and biodiversity. Many also expressed concern that the genetic material of transgenic plants can be transferred to non-GM plant varieties. Although herbicide-resistant transgenic plants, the same quality, if transferred to weeds can make it very difficult to control weeds. Apart from these, it was found that some genetically modified foods, developed by the animals to cause allergic reactions in some individuals. However, no incidence of these severe allergies have been reported in case of manufacture of food for human consumption.

Another issue raised by critics of GM crops is that these plants can release genes of antibiotic resistance in soil, which can cause soil micro-organisms resistant to antibiotics. Apart from these, laboratory studies have suggested that the introduction of genetically modified crops may affect other organisms. How, for example, Bt corn pollen can affect the larvae of monarch butterflies and moths, if they feed on the leaves of the plant milkweed, covered with pollen from maize Bt, but the supporters of GM and GM crops have refuted the claim this and claims that Bt corn pollen on milkweed leaves can reach a high level of concentration to produce such effects.

Briefly, transgenic plants, risks to human health and ecosystems is a controversial issue. Therefore, further detailed studies and investigations to resolve disputes related to transgenic plants, so that consumers can discover the truth about these plants and genetically modified foods. Apart from these, there are many ethical issues are also associated with transgenesis, which must also be adequately addressed.
