Chapter 98 Genetic modification and the twenty-fourth pair of chromosomes
To be honest, it was the first time Cheng Ying considered the idea of throwing penguins from Antarctica to the North Pole to become invasive alien species. It was unrealistic no matter how he thought about it.
But that thing is a kind of penguin-like soul beast. Maybe the soul beast is different from ordinary animals...
It's just that it's still far behind man-made invasive alien species like him. The main reason why ordinary invasive alien species cause harm is the lack of natural enemies for unrestricted reproduction, such as rabbits in Australia.
They ate up almost all the pastures there. In the end, humans found a bacterium that could restrain rabbits, and they successfully curbed the number of rabbits on that continent.
The characteristics that successful invasive alien species must have are no natural enemies or rapid reproduction. First of all, crayfish is a typical failure case.
It is true that animals in nature have no natural enemies, but they have evolved to be so delicious...which unfortunately led to them attracting the attention of the terrifying erect ape.
That is a group of terrifying races that have eaten countless species of animals for tens of thousands of years. It can be said that they are more terrifying than natural enemies.
Therefore, this species must not be delicious. It is even better if it is poisonous and inedible, otherwise it will be eaten up.
This is actually easy to do. Just make their roots, stems and leaves rich in a lot of wood fiber. This is not difficult to do. This can make this thing extremely unpalatable, even for livestock and other animals.
The kind you are willing to taste.
As for the issue of natural enemies, compared to herbivores and insects, the natural enemies of plants are actually more in competition with other plants.
Herbivores and insects can indeed destroy a considerable part of the plants, but the majority of them actually fail to germinate from the seeds.
Plants that are blocked from sunlight by weeds and trees are likely to die in their infancy. Even if their fruits and seeds are not eaten or destroyed by insects and other organisms, they will not be able to thrive until they bear fruit.
To solve this problem, we need to improve the cold resistance and growth rate of the plant. Of course, the most direct way is to increase the height of the plant leaves so that they can block other low weeds after they grow.
But in this case, its reproduction speed will be seriously affected, and if its appearance changes, then this thing will not be considered an orchid.
Cheng Ying's original intention to create invasive alien species was to collapse the orchid trade. If these things looked different from orchids, wouldn't it be meaningless?
So the way he thought of was to improve the cold tolerance of plants. This is actually easy to understand, just like winter wheat can be grown in the south. In the winter when everything dies, most plants will wither. If it can grow and sprout at this time,
, then he can suppress all other plants in early spring.
Basically this is the situation without much change, because if there are too many changes, it is very likely that people will notice the difference between this thing and normal orchids. If that is the case, the orchid trade can still survive.
As for how Cheng Ying did it, we have to mention the directional stimulation of genes by soul power, just like the extra pair of chromosomes in the human body.
After Cheng Ying's analysis, that pair of chromosomes should be the determined martial soul of the human body. What surprised him most was that using the isotope labeling method, he found that the gene sequences on the chromosomes of the same soul master were different when he was at different levels of cultivation.
Only the twenty-fourth pair of chromosomes had changed, which gave him a guess, that is, this pair of chromosomes had undergone directional evolution under the stimulation of soul power. This is why martial souls can become stronger and even evolve with practice.
s reason.
The evolution of martial souls is very difficult, and it may largely depend on the degree of genetic modification. Just like the second awakening of the original martial soul mentioned in the second part, it is likely that it is the chromosome of this pair.
Qualitative changes have occurred in genes.
As for how to use soul power to stimulate the targeted change of the pair of chromosomes in the human body, it is a bit difficult. After all, human embryos cannot be modified casually. Unlike plants, there are many seeds that can transform failed products.
Throw them all away.
Originally, Chengying was not able to make such subtle adjustments before going to sea. The main reason was that this kind of transformation required a lot of experiments. Just like trying his luck, different frequencies of soul power output would produce completely different results. It was a bit like
Use radiation to create mutant or transgenic plants.
The difference is that soul power is more stable than radiation and phages in modifying plant genes, and it is largely affected by will. In other words, you want to make the genes of plants determine certain traits.
Change it, and then use your soul power to stimulate it, and you will most likely get a plant that meets your vision.
But this is very large, and it may actually be only 1% or lower. If he were to stimulate one by one by himself, it would definitely take a long time to get a group of seeds that meet the conditions.
But with the soul guide, he could simply inject soul power and let the machine do a lot of repetitive work for him, increasing the efficiency by more than a hundred times.
Cheng Ying still hasn't figured out why the soul power changes plant genes, but he is pragmatic and can use it, and the principles can be explored while using it.
It was with the help of a machine similar to a seeder and the isotope labeling method that Cheng Ying was able to obtain the necessary invasive plant strains. As long as they are released, next year's orchids will turn into real devil's flowers.
He plans to improve rice and wheat after returning to Douluo. Although sweet potatoes and potatoes are high-yielding, they are only eaten during disaster relief. It is okay to eat them occasionally, but it will kill you if you eat them every day.
Maybe in the future he can be known as the Patriarch of Magic Rice or Daode Tianzun in Douluo. Although he is definitely not as awesome as Mr. Yuan, there is a demon world here. Who knows if he will become a god by believing in it?
!
To be honest, just because of the improvement of grains, in ancient times, it was enough to go to the temple and squat. Chengying felt that with this guarantee, even if something unexpected happened one day, no one would dare to touch him. He just wanted to think about it.
You can probably imagine how angry the Chinese nation would be if the Patriarch of Magic Rice was assassinated.
After Cheng Ying burned a bunch of eliminated seeds into ashes, he also gave Ice Emperor a space ring. After discussing it with her, the two of them split up to spread these seeds to all parts of the continent.
As for why all the failed products were burned, Chengying was mainly worried that there would be some uncontrollable genetic mutation and some bad mutants would grow...
What he didn't notice was that among the ashes, two seeds remained intact...
