Chapter 41 Moon City (11)

…In the face of the unknown, we should be more cautious. Building houses on the moon is related to the life and death of residents, and we should proceed step by step. If we are very happy with the excellence, many people's lives may be sacrificed in vain because of our mistakes. In addition, in the gradual work, we are also growing. Compare, have our current skills greatly improved?…

660 successfully passed the meaning of 015 to the chief engineer of the second engineering team, and was highly recognized by the latter.

After completing those things, 660 returned to Earth from the moon. He also sent a letter to 015 in an encrypted email address on 660 on the spacecraft.

"The Moon City project is progressing smoothly, and all residents are satisfied with the life of Moon City. They are very enthusiastic about life. The residents interact frequently. The residents have a good relationship with the Second Engineering Team and they often conduct transactions. The engineering team helps residents transform and expand their residences, while the residents provide the engineering team with fresh fruits and vegetables and other agricultural products.

After the establishment of the Lunar City factory, industrial production was also very smooth, and a large number of products can be produced for use every day, while the remaining products were properly preserved for the maintenance and further expansion of the Lunar City.

In addition, in the past few days, our group has had an unexpected harvest in Moon City, which is a leaf. The leaf comes from an apple tree, which was transplanted from the earth. According to the resident, he accidentally discovered this leaf while taking care of the apple tree. This resident has years of experience in taking care of the fruit tree. He judged that some cells of the apple tree had a genetic breakthrough.

Generally speaking, gene mutations are harmful to organisms, but some gene mutations are beneficial to organisms, and organisms are becoming more and more adaptable to the environment. The accumulation of beneficial mutations changes the gene pool of organisms and ultimately leads to the generation of new species.

This leaf looked more energetic than other leaves. So the resident cut the leaf and cultured it. After tissue culture, he found that the apple seedlings cultivated this time were more vigorous than other apple seedlings.

We have brought some of the seedling samples to the spacecraft, and they will return to Earth with us and then come to the base for further research.

In fact, the lunar environment is very suitable for a breeding base. Due to the selectivity of the lunar environment, we can cultivate crops that are more suitable for other planets."…

Space breeding: also known as space mutagenesis breeding, is to send crop seeds or test tube seeds to space, and use the mutagenesis of special environments in space that cannot be simulated on the ground (high vacuum, cosmic high-energy ion radiation, cosmic magnetic field, and high cleanliness) to mutate the seeds, and then return to the ground to select new seeds and materials, and cultivate new varieties of crop breeding new technologies.

Scientists believe that space breeding mainly induces genetic mutations in plant seeds through space comprehensive environmental factors such as strong radiation, microgravity and high vacuum. Due to the morphology, physiology and evolution of Earth's plants for billions of years, once they enter a weightless state and are affected by other physical radiation, they will be more likely to produce genetic mutations that are difficult to obtain on the ground.

The space environment, which combines space radiation, microgravity and high vacuum, has a strong impact on the physiological and genetic traits of plant seeds, but it is still unclear what factors mainly affect and how it affects them.

After experiencing the seeds of crops traveling in space, after returning to the ground to plant, not only the plants have significantly increased and thickened, the fruit shape has increased, and the yield has increased generally compared with the original, but the quality has also been greatly improved. So far, space breeding has achieved good results, but it is still unable to control the mutation direction of the seeds and can only allow it to develop. This is a scientific gap in the world today, waiting for scientists to make further explorations.
