Military Technology

The debate and disagreement about genetically modified technology has never stopped since the technology came out. The debate on this technology can be said to be an issue that is being debated by today's academic circles, society, and the public. It has long since ceased to be an issue debated by the academic circles, but has become an issue of concern to all mankind. .

Transgenic technology refers to the use of modern biotechnology to introduce and integrate the desired target gene into the genome of an organism after artificial separation and recombination, so as to improve the original traits of the organism or endow it with new excellent traits.

In addition to the introduction of new foreign genes, the genetic characteristics of organisms can also be changed through transgenic technology to process, knock out, and shield the genes of organisms, so as to obtain the desired traits.

The main process of this technology includes a series of genetic engineering techniques such as cloning of foreign genes, construction of expression vectors, establishment of genetic transformation systems, screening of genetic transformants, analysis of genetic stability, and backcrossing.

Scientists and researchers can use transgenic technology to artificially breed some very good new plant varieties.

These brand-new plant varieties have many very obvious advantages compared to traditional plant varieties.

For example, GMO technology can accelerate the growth rate of crops, enhance disease resistance, increase yield, enhance the ability to adapt to the environment, and enhance the ability to resist herbicides and insecticides.

Plants are vulnerable to other weeds and pests, and transgenic technology involves inserting some pest-resistant genes into the plant so that it can resist and immunize related pests.

In addition, weeds and insects in the farmland have a greater impact on crops. Generally, when clearing large areas, it is necessary to spray a large amount of herbicides and insecticides.

When these herbicides and insecticides kill these weeds and insects, they will also affect or even harm crops or specific plants.

In this way, when there are weeds and large-scale insect damage, such as locusts, seed flies, greasy insects, etc., you can safely and boldly spray herbicides and insecticides, so you don’t have to worry about damage to crops and specific insecticides. Plants cause damage.

What's more, it is also the transgenic or gene editing technology that Wu Hao and the others are researching.

That is, cloning some stress-resistant genes and transferring them into plants can improve the resistance of plants to adversities such as drought, low temperature, and salinity.

For example, they are cultivating a new type of transgenic Haloxylon tree, which has transferred some of the genes of moso bamboo. Not only does it increase the plant height of the Haloxylon tree several times, but it also has the rapid growth ability of moso bamboo, which can rise to a height of several meters in a short period of time, which is difficult for plants in desert and arid areas.

In addition to large-scale application of agricultural plants, transgenic technology is also used in industry, medicine, fishery, animal husbandry, and even environmental protection.

For example, in industry, it can be applied to industrial fermented food strains, such as the improvement of yeast and lactic acid bacteria. In addition, transgenic technology can also be used to improve the production of food additives and processing aids.

In medicine, transgenic technology is also widely used. Transgenic technology can be applied to the production of protein and peptide drugs, such as the production of rare drugs such as insulin, interferon, immunoglobulin, human hemoglobin, and granulocytes. Animals and plants can also be used to produce vaccines, such as hepatitis B surface antigen gene, foot-and-mouth disease virus protein gene, rabies virus G protein gene and so on.

In fishery, transgenic technology can also be used to improve fish breeding performance and enhance its ability to resist cold and disease. According to related reports and published papers, a variety of mammalian and bird-related genes have been successfully transferred into the fish genome, resulting in significantly increased muscle protein content and feed conversion rate and accelerated growth in transgenic fish .

In addition, technicians also use transgenic technology to cultivate ornamental fish, such as the small tropical ornamental fish that have become popular and even flooded in recent years. They are very rich in red, green, and blue colors, and some even fluoresce at night. These fish do not exist naturally, but technicians transfer the genes of some luminous jellyfish and deep-sea fish to these fish, thereby cultivating brand-new species.

In the livestock industry, the same genetic modification technology is also showing its talents.

It can improve the production traits of livestock and poultry. Through transgenic technology, it can promote the growth rate of animals, improve the utilization efficiency of feed and shorten the growth cycle. Secondly, the application of transgenic technology can improve the disease resistance of livestock and poultry. The antigene of the pathogenic gene of the pathogen can be introduced into the livestock and poultry, so as to play a role in disease resistance.

The last is environmental protection. One is what Wu Hao and the others are doing. They are cultivating some better drought-resistant, wind-sand, saline-alkali, and barren-resistant plants, and planting trees in arid desert areas to prevent wind and sand fixation. Improve the environment.

In addition, the characteristics of certain plants, bacteria, and microorganisms that absorb heavy metals and other toxic elements can be extracted, and the related genes of these plants, bacteria, and microorganisms can be extracted, and then super plants that can absorb heavy metals and toxic elements can be cultivated. So as to control these polluted areas and play a role in purifying the environment.

Having said so much, it seems that transgenic technology is perfect and can help us humans solve various problems. It can be said to be a great biotechnology that can change the human world and even human civilization.

However, the risks it brings have also become a common concern among academic circles, society and the public.

Some countries and regions even set up bans to strictly control the cultivation and production of such genetically modified plants and genetically modified technologies.

For example, the European Union implements a mandatory labeling system for genetically modified products, and the House of Representatives of the United States passed the ban on the cultivation of genetically modified corn. There are also some countries that directly prohibit the planting of genetically modified crops, and strictly restrict the circulation of related genetically modified crops.

The reason why people are so worried about genetically modified technology is that they are afraid of serious ecological disasters and dangers brought about by the abuse of genetically modified technology.

For example, many people believe that genetically modified technology itself still has some hidden dangers that cannot be confirmed yet but are hugely harmful, including threats to the earth's ecological environment and human health.

In addition, in terms of ecology, if the relevant genes of transgenic crops are transferred to relative wild species, it will pollute the entire gene pool of seed resources, thereby changing regional plant genes, or even global plant genes, which will cause great harm to the ecological environment .

Moreover, humans are also a part of the natural ecosystem, and people worry that these genetically modified plants may also endanger the genes of some animals that have been fed with plants, and eventually affect human genes.
