Chapter 868: Grain Production
Hua Jingyue conducted many such experiments when she had nothing to do. This kind of experiment is regarded by Hua Jingyue as a process of perceiving the Dao Method. So, tirelessly.
Therefore, these experiments do not have a definite directionality. However, Hua Jingyue found that this kind of experiment, its own skills, and the potential that can be unearthed, have far surpassed the natural and crude techniques of changing plants, for example, grafting techniques.
So, I took all kinds of plants to practice. I hope that I can break the shackles of my own genes, find an opportunity, and take the step of breaking through the Yuan Infant Stage and achieving the Transformation Period. The experiment of dismantling the rice gene into fragments and introducing it into bamboo as a foreign gene is also one of these experiments.
The genes of an organism, even the simplest single-celled organisms, are very complex and sophisticated. It stands to reason that once its original structure is broken, the probability of achieving a new balance and producing a new species through the introduction of foreign genes is almost negligible.
After the collapse and destruction of the gene chain, most organisms have no choice but to die.
After all, this genetic mutation did not evolve naturally. The change was sudden, and unreasonable.
Even naturally occurring genetic mutations often lead to the death of living organisms. For example, cancer, and some very violent viral infections.
The evolutionary process of life is a process of trial and error. Genes are constantly changing and adjusting. And mercilessly weed out the wrong changes. Only some changes and adjustments are left that are beneficial to life itself. Thus giving rise to evolution, and giving rise to new species.
It's just that genes that are born naturally change slowly, at an extremely slow rate. According to the study of biological evolution, the emergence of a new species adapted to the environment will take tens of millions of years to evolve.
In the course of tens of millions of years, a species has experienced at least billions of genetic trial and error within the population in the course of evolution. This is the only way to arrive at an optimal solution. Get a new population.
In fact, there is no essential difference between artificial genetic adjustment and the natural trial-and-error process in natural evolution. However, the nature of natural genetic transgenesis through viruses, that is, the natural genetic exchange between all living beings, is not much different from the artificial genetic transgenesis carried out by human scientists.
"The great origin of the Tao comes from the sky, the sky does not change, and the Tao does not change" and "Under the sun, there is nothing new" are harmonious and different, and the meaning is far-reaching.
Of course, Hua Jingyue has a deep understanding of the essence of plants and trees, and after being exposed to modern biology, botany, agriculture and other sciences and research that go deep into the genetic level, it is verified by her own experience for thousands of years, and she feels that it is perfect and compatible.
Therefore, Hua Jingyue understands these modern botanical knowledge very quickly. When I was doing the experiment, I couldn't help but add some of my understanding of the creatures of plants and trees over the past thousands of years.
As a result, in an experiment, a plant based on rice and bamboo was constructed that combined the characteristics of the two. Of course, there is also a natural basis for the emergence of this species.
Whether it is rice or bamboo, according to the division of genera and species of the Phylum Order, they all belong to the grass family.
It's just that one belongs to the subfamily Bamboo and the other belongs to the subfamily Poaceae.
In nature, the division of genera and species is very important, in addition to the fact that this hierarchical division can help humans clearly define how many species there are in nature. It can also give a detailed definition of the kinship in the evolution of organisms.
And the definition of this kinship relationship is inseparable from genes. The closer the species, the greater the degree of genetic similarity between them. And the lower the threshold for reproductive isolation.
Hua Jingyue handed the seeds in the small glass bottle to the elder and said, "After cultivating this species of rice and bamboo, I will try to plant it. Discover this new plant that combines the best of both worlds. Crucially, this plant can naturally produce seeds. ”
"And the seeds can already maintain their stable traits. The vial of seeds in my hand is already the seed of the third generation of plants. ”
The elder asked, "What are the benefits of this new crop compared to rice and bamboo?"
Hua Jingyue said: "This new crop actually looks more like bamboo. The height of each plant can reach more than three meters, and in the process of growth, almost every bamboo node can produce tillers. ”
"Generally speaking, bamboo doesn't bloom easily. It usually blooms only when the cataclysm comes. If there is no cataclysm. That's only when the longevity is about to end, and it blooms once. and produce bamboo rice. As a result, many bamboos bloom over decades and then die. ”
"The life history of rice and bamboo is actually very similar. It dies when it blooms and bears fruit. Moreover, between bamboo and rice, the structure of the flowers is basically similar. ”
"This time it's in the midst of genetic reconstruction. I compressed the growth rate of the bamboo, with the overall lifespan, to replace it with the genes of the rice. And changed its fruiting state, and also replaced it with the gene of rice. After adjustment, it only takes about two or three months for these bamboos to grow and mature, bloom and bear fruit. ”
"After all, bamboo grows much faster and more efficiently than rice. ”
"After genetic reconstruction, the bamboo that grows will have tillers of branches and leaves on each bamboo node, and when it blooms, there will also be tillers. A three-meter-tall bamboo, with a five-centimeter knot, will have about 60 tillers. Among them, there are about forty or fifty effective tillers. ”
"And there are only more than 20 tillers of a rice plant. The effective tillerers are only about half, that is, about ten to fifteen. In other words, in terms of tillering, the effective number of tillers of a newly planted bamboo is four to five times that of rice!"
"This newly planted bamboo produces bamboo rice with particles similar in size and shape to rice. Generally speaking, the yield of a rice plant is about 50 grams. And this kind of new bamboo, the yield of rice per plant, is about 200 grams to 300 grams!"
"That is to say, under the condition that the growth density and growth cycle are the same, the grain yield of this new bamboo will be four to five times that of the original rice! If we really make up our minds to popularize planting on a large scale, China's grain output will increase several times in a short period of time!"
Hua Jingyue's words made everyone, including Tianbin, shocked!
