Chapter 157 (2/2)

”OK, Mr. Xu, take your time...”

Zhou Wen watched Xu Yuting's spenter start slowly and disappear in sight.

He turned and went upstairs, took some things and was ready to leave.

Chen Zhiyuan came over and said with a smile: ”Hey, Lao Zhou, the last time that Xiaomin, has been asking me why you can't get through to your phone, you pulled her black?”

Zhou Wen said, ”no, I just casually reported a number.”

Chen Zhiyuan bared his teeth and said: ”niuforced, you have preliminarily mastered the essence of not taking the initiative, not refusing and not being responsible.”

”Get out of here, because of you, I'm all degenerate now.”

”Don't say that. Everyone has a love for beauty. At most, it is a little fraternity. How can it be called depravity? ”

”OK, OK, go on with fraternity. I went to the laboratory ~ ”

Zhou Wen took the car key and was ready to leave.

”Lend me your car. I'll see a client later. My car is too much,” Chen said

”Then give me your car.” Then Zhou Wen threw the key to Chen Zhiyuan.

”I lent my car to people in the company to do business,” Chen said

Zhou Wen had no language: ”what am I driving?”

He said, ”Ferrari, you laugh. Tens of millions of cars can't be thrown into the garage every day. ”

Zhou Wen: ”so Sao Bao, how can I drive to the laboratory?”

”Or Can I borrow an electric car for you from Xiao Liu at the front desk

”Roll ~”

”Ai ~ OK.” Chen Zhiyuan ran away with the key.

”That's the Sao Bao.” Zhou Wen is too lazy to call didi car. He takes the key of Ferrari f12tdf from his office and goes downstairs.

……

World Biotechnology Institute, 404 Jinhu Industrial Park.

In the open office, seven or eight people, including Wang Hua, Sun Xin, song Xuezhang, Bai Xuan and Luo Chunlei, are gathering to study and discuss.

This is the person in charge selected by many doctors themselves. He has excellent academic character and certain leadership ability.

We all agree.

The technology they are discussing at this time is ”mutation breeding”, which is one of the key projects to be developed in the next step.

The so-called mutation breeding technology is similar to the rice aphid gene transformation technology studied by Zhou Wen before.

It is to use physical, chemical and other factors to induce the mutation of organisms under artificial conditions, and then select and cultivate new varieties of animals, plants and microorganisms.

For example, chemical mutagens are more commonly used alkylating agents, such as ethyl methanesulfonate (EMS) and diethyl sulfate (DMS).

The method is very simple, dilute it to a certain concentration, and then put the seeds to be mutated and soak for a period of time.

After that, the seeds germinated, and the plants with the required phenotype were selected, and then the mutants that could be stably inherited were selected by self crossing or hybridization.

Of course, the workload of screening is very large, for example, sometimes it is necessary to screen tens of thousands of seeds to find the desired traits.

There are also physical mutagenesis.

Its principle is to use a variety of radiation to accelerate the mutation rate of plants, among which gamma ray, α - ray, β - ray, gamma ray, Χ - ray, ultraviolet radiation and so on are commonly used. These operations need special equipment.

One of the more famous is the laboratory of Japan benzene Radiation Breeding Institute. They built a tower for radiation treatment, surrounded by a field.

After some discussion, we selected two research objectives - grapes and strawberries.

These are two kinds of fruits common in greenhouses in eastern Jiangsu Province.

Just as they were ready to assign tasks, the sound of footsteps came from the door of the conference room. People turned their heads subconsciously and found that it was Zhou Wen who had come.

”Zhou Suo is here.”

”Zhou Suo Hao.””Ha ha, everyone is here. Sit down...”

Zhou Wen reached out and motioned for them to sit down. Then he sat down beside Wang Hua, ”what are you talking about?”

At the same time, he has seen the research schedule on the table, as well as the relevant materials about mutation technology.

Song Xuezhang, sitting opposite Zhou Wen, said, ”we have just chosen two targets...”

With song Xuezhang's account, Zhou Wen's ears suddenly sounded four or five task prompts.

Zhou Wen:

He has never received so many tasks at once.

Open the system tasks and have a look. There is a long row of new tasks on the list.

[task 1: radiation breeding.

Requirements: establish a research group of grape radiation breeding.

Reward: 2000 discipline experience, 1000 points, one prize opportunity (bronze)]

[task 2: chemical breeding.

Requirements: establish grape chemical breeding research group.

Award: 2000 discipline experience, 1000 points, one prize opportunity (bronze)]

[task 3: radiation breeding 2.

requirements: establish strawberry Radiation Breeding Institute 】

the requirements of task 3 and task 4 were almost the same, except that the requirements changed from grape to strawberry.

The first few tasks, in his view, are the system to send points.

But the latter one is exaggerated.

For example, task 5 requires the cultivation of grapes with an average of 50 grams per grain.

Fujimino grape, the largest grape variety in China, has an average of only 22-30 grams per grain, and the largest grape variety is only 35 grams, which has nearly doubled.

Task 6, it is required to cultivate a single strawberry with a maximum of 500g.

This is even more exaggerated. The world record is only 231g, which has more than doubled. The system really looks up to him
