Since the cross-species problem of genes has been mentioned, Boss Tang informed everyone of the latest scientific progress in his agricultural empire, saying that he had discovered a bacterium called Agrobacterium tumefaciens. This bacterium is a gift from nature and has the miraculous property of being able to insert its own genes into the transport DNA of the plant, directing the expression of 8 genes on the plant.

In other words, this bacterium can express its genes on plants, and can infect more than 100 plants. Its original purpose was to synthesize a compound called "coronanine" through guò to induce plant carcinogenesis.

Biochemical methods can be used to alter the genes originally expressed by Agrobacterium tumefaciens, and only use its infectious properties, so that the genes can be expressed across species.

Like many of Boss Tang's previous projects, it turns out that people already have a reliable plan. Liberty and others sighed at this, and it seems that agricultural technology is about to change dramatically.

Recently, some chemists have synthesized DDT, and some scientists believe that it can be used as a pesticide, which has aroused the vigilance of Boss Tang. Therefore, Boss Tang wants to invent a cheaper agricultural pest control method than biological pesticides before DDT is applied on a large scale.

The BT protein that was previously applied to the biopesticide industry by Boss Tang is actually just some protein crystals secreted by a bacterium called Bacillus thuringiensis, which can be activated in the intestines of a variety of insects and pierce the intestines of insects to kill them.

In addition to the BT protein, there are also animals such as scorpions and spiders, and in order to kill their prey more efficiently, they have also evolved proteins that can kill some insects.

The best way to find insecticidal genes (like antibacterial drugs, there can be no one-size-fits-all insect-resistant genes) is to directly look for the natural enemies of a certain pest. For example, the natural enemy of the cabbage insect, the butterfly pupal golden bee, can produce insect immunosuppressive factors, which can inhibit the immune system of the cabbage worm and affect the growth and development of the cabbage worm.

All of these insect-resistant substances have the potential to be utilized through cross-species gene expression. Making a new variety with insect resistance genes is equivalent to treating the plant itself as a pesticide factory, and its efficiency can be imagined. This is the cheapest and most effective way to control pests.

With such new varieties, even the production of pesticides is exempted. The Windsor agricultural empire is about to monopolize the world's agriculture. Of course, we can't say that, we have to say something like "benefiting hundreds of millions of farmers" and other lofty words.

In addition to insect and disease resistance, it is also necessary to increase production. Genetics-based breeding has only been produced for a few years under the leadership of Boss Tang, and now it will enter a new field. The core technology is inspired by the composition of the Earth's atmosphere in ancient times, when plants and animals were large because of the high concentration of carbon dioxide.

To understand why carbon dioxide concentrations have an impact on plant growth, we have to study the biochemical processes by which plants fix carbon dioxide.

It turns out that a key role in the carbon dioxide curing process is a catalyst called ribulose carboxylase diphosphate. This catalyst is also active to oxygen, so oxygen and carbon dioxide compete together for the active site of the catalyst, which makes the plant sensitive to the concentration of carbon dioxide.

Over the course of thousands of years of evolution, some plants have evolved ways to increase the concentration of carbon dioxide locally in their own bodies. It's like the feeling of an airplane flying high in the air and needs a turbine to compress the air because the air is thin. Plants use ATP as energy to pump carbon dioxide into the environment.

In addition to this, mesophyll cells have evolved a PEP-carboxylation pathway to fix carbon dioxide. In this process, CO2 is immobilized by phosphoenolpyruvate (PEP). Carbon dioxide is converted to oxaloacetic acid. This is a four-carbon compound, and later scientists abbreviated this carbon sequestration method as C4.

In places where the temperature is high, the catalyst for carbon sequestration has a high affinity for oxygen, so in the evolutionary process, tropical crops were the first to feel the pressure, and C4 plants such as corn and sugarcane were the first to appear.

The C4 process has a high utilization rate of water, producing a substance with a dry weight of 1 g, C4 plants only need 230–250 ml of water, while C3 plants consume two to three times this amount, so arid local species will be the first to make natural selection. Millet, a C4 plant, is particularly drought tolerant, while sorghum, which initially grew like maize, originated in arid, hot Africa.

The C3 to C4 process, the increase in efficiency is like the difference between a propeller engine and a turbofan jet engine, and if C3 rice can be added to the C4 gene, it is estimated that the yield can be increased by 35%.

The benefits are not only this, the world's highest yield of grain is corn, its roots are symbiotic with nitrogen-fixing bacteria, and nitrogen fertilizer, the largest part of the fertilizer, can be saved. Therefore, once the C4 transformation rice project is successful, the benefits are huge.

Introducing a desired gene may seem simple, but it is far from that simple. Because this technology that completely changes the carbon sequestration mechanism of plants requires the support and cooperation of many genes.

It makes sense for Boss Tang to let the Darwin Institute study a large number of genetic evolution processes, which is not a purely academic project without use. Through the evolution of various genes, the differences between C3 and C4 can be sorted out to serve this revolutionary genetic engineering.

The genetic technology of Windsor's agricultural empire was so powerful and suffocating that it was difficult for the Entente and conservative people to imagine the consequences of exchanging genes for completely different organisms. Even quite a few scientists, due to conservative instincts, are very afraid of the emergence of such technology.

In any case, the competition in science and technology is fierce, and whether ordinary people watch this documentary or not, scientists and politicians of the Entente countries must study it deeply, because the amount of information is too large.

And if politicians want to fool voters into supporting their tech policies, they will definitely mention this documentary, so that voters will be encouraged to watch the film, and the result is that this documentary is an unprecedented hit. Important things are never buried.

There are also those who believe that cross-species gene expression is a fantasy and simply impossible. Boss Tang responded to this suspicion in the loudest way, and soon the first cross-species genetic breed was cultivated: fluorescent fish. It is based on the zebrafish, a very beautiful ornamental fish with lines, which is even more surprisingly showy when it can shine.

As if to show off his skills, the fluorescent fish created by Boss Tang this time was not only inserted into a foreign gene, but a bacterium parasitic in the body of zebrafish. Because bacteria multiply quickly, genetic engineering research is also fast.

The team inserted two genes into the bacterial gene, one is the luminescence gene and the other is the quorum sensing gene. They are all luminescent creatures from the ocean, which not only emit light, but also rely on quorum sensing to enhance the host's symbiotic effect.

Fish with quorum-sensing luminescent genes can respond as soon as they sense some kind of light, and the result is that all bacteria glow together. Therefore, Boss Tang's dazzling fish can control it through guò lights, originally the zebrafish was very ordinary, but when it suddenly sensed a faint light, it immediately glowed all over its body.

Xuanji* also made these lights into green, red, and yellow. The team's scientists joked, "You can use them as traffic lights." ”

Boss Tang responded with a smile: "What do you think I specialize in the three colors of red, green and yellow?" ”

What the? Don't...... Soon, the news appeared in the China News newspaper that the big boss of the Windsor consortium had donated a three-color fluorescent fish to the Beijing Municipal Traffic Police Department, which was placed at the intersection in the form of a fish tank with columnar glass piles for passers-by to watch calmly while waiting for the red light. Note that the luminescent bacteria in this fluorescent fish have quorum-sensing genes, so they can be synchronized with the color of the semaphore!

Passers-by can enjoy the fish boldly and confidently, and will not miss the street lamp changing color, which is an elegant solution to relieve anxiety. The Arabian Nights has become a reality so quickly, and this slap in the face is so loud.

Those who are interested in novelties immediately go to the store and search for "fluorescent fish". Sure enough, Boss Tang started to do this business, and it is definitely not Boss Tang's style to make money or not. Thanks to the Windsor Consortium's brand effect, fluorescent fish quickly became the hottest pet. Compared to the money earned by the boss, the small loss donated to Beijing is nothing at all.

There may be a more painful punishment in this world than killing the other person, and that is to make myself so beautiful that you will die of jealousy. This is the plan that Boss Tang made for the United Nations, and he advised his national leaders not to think about conquest by force.

The second round of cross-species genetic technology: cotton improvement. Most of the cotton is white, and there are also natural colored cotton, but its color and yield are not as good as the white cotton that has always occupied the mainstream of the market. Direct growth of colored cotton can eliminate the dye agent, and the characteristics of the cotton itself can be completely unchanged.

When Boss Tang chose the color, he was influenced by the underwater treasures that kept coming out of the water, and the treasures were mostly porcelain, and Boss Tang especially liked the plain porcelain of the Song Dynasty. When he built the Great Eastern, he had already given the hull a beautiful azure color.

Now that he had the opportunity to set the tone for the color cotton that would have a profound impact on the clothing industry, he selected from a variety of plain porcelain from the Song Dynasty. It just so happened that there was a shipwreck when the Northern Song Dynasty sailed to Southeast Asia recently, and a large number of plain porcelain was placed in the Nanmu Hall of Prince Gong's Mansion.

The most eye-catching is always red, and a red tea cup in front of Tang Ning resembles ox blood, which is unusually unique, which is the first one he fancies.

Louise asked, puzzled, "Is any color fine?" ”

Tang Ning: "Well, not now, I will be transferred out in the future." As our biologists learn more about the genes that control color, anything is possible, and I'm just here to determine the color. The color of the porcelain in the Northern Song Dynasty is really beautiful, and I don't know where it is higher than the gaudy vulgarity advocated by Kang Yongqian. ”

Louise smiled: "Yes, you have always liked the Song Dynasty, I remember that when the treasures of the Old Summer Palace were auctioned, you grabbed Song Huizong's painting and painted a parrot." ”

Tang Ning smiled: "Yes, I seem to have given you something at that time, is it still there?" ”

Louise: "Of course, I always take it with me when I go to Canada, it is Mr. Lang Shining's "Hundred Horses". At that time, the world's largest tycoon waved his hand and gave the little girl a painting that cost 7,000 pounds, and Louise still feels sweet when she thinks about it.

Of course, they also remembered the feat of Xiao Lin Fell to buy the Old Summer Palace at that time, and they couldn't help but smile together. Louise didn't know that in fact, Little Phil's ideal had come true, and now the Old Summer Palace was in Boss Lin's pocket, but she rarely had the opportunity to enjoy it.

Tang Ning said: "The color of Song porcelain is elegant to carve, it is very suitable for underwear, it seems that color cotton undyed underwear will become one of the core competitiveness of our Victoria's Secret." ”

Subsequently, he also selected the azure color of Ru kiln, which is simple, thick, natural, soft and elegant, and cannot be missed.

The third is Longquan kiln plum green, the enamel is shiny, verdant, and the color is comparable to jadeite.

The fourth is the green glaze of "green as the first birthday of spring".

The fifth is Yongle "Yingqing". In fact, this is from the Ming Dynasty, from the previous shipwreck, was put here by Louise, Tang Ning visited a bowl, its bowl has a texture, the background color is similar to Song Ding kiln, but in fact it is not, the local tyrant does not know, anyway, he is happy to see the hunt, it can also be called a chaotic mandarin duck spectrum. If a knowledgeable designer doesn't dare to ask too much, he may refer to the color of the Dingyao one-color porcelain.

After Tang Tuhao chose these five, he also gave the project a name: Victoria's Secret Color Glaze
