He was like this, not to mention Shen Ning and a few others. He got a guinea pig so casually, which made Shen Ning and the others a little scared.
As for Yang Fang, she took off her gloves with a smile, threw them into a yellow medical trash can nearby, then squeezed some hand sanitizer to wash her hands, and wiped them after use.
After finishing her work, she smiled and said to everyone: "I'm used to it, don't be surprised. This white mouse has completed its mission. Next, we will send it to the laboratory for dissection and observe its internal body." Penetration of toxins.
Finally, the bodies of these white mice and the medical waste will go into the incinerator, be harmlessly treated, and then buried in deep pits to prevent these wastes from polluting the outside environment."
Wu Hao glanced at Shen Ning and the others who were still a little frightened over there, then smiled at Yang Fang and asked: "Tell me about this Venus flytrap, why did you cultivate such a dangerous species and have to leak it?" The spread will have a serious impact on the entire natural ecosystem and even destroy the biological chain ecosystem in some places."
"Haha, this is purely an experimental exploration. You can rest assured that these plants cannot be leaked out without permission. We have two main purposes for cultivating this Venus flytrap. First of all, we want to find the flytrap. Some controller genes in the flytrap have been released to respond to movement. The flytrap is probably one of the rarest moving plants in the world. We hope to extract these genes that control plant movement and then implant them into other plants. On some plants, these plants also have functions similar to Venus flytraps.
To give a simple example, we want to cultivate a flower that will bloom quickly when people approach or touch it. Then after a while, it will put away itself and wait for the next time it is touched.
As for the gene that controls the blooming of this kind of flower when touched, we plan to extract it from Mimosa pudica. The leaves of Mimosa pudica will quickly become sensitive when touched by the outside world. We plan to implant this gene into flowers.
This is not done for novelty, nor is it all for looking good. In fact, it has great application value.
For example, pollen transmission in the desert has always been a big problem for plant and fruit breeding. Because there are relatively few insects in desert areas, it is very difficult to transmit pollen. Compared with some areas with more insects, pollination in desert areas takes longer. Much.
However, due to the harsh natural conditions in desert areas, such as high temperature, drought, and wind and sand, these flowers may have been burned and dried up by the high temperature and drought before they were pollinated, or they may have withered away due to the wind and sand.
And if we implant the genes of mimosa into these plants, then the flowers of these plants can be retracted directly when they are affected by high temperature or external force. In other words, only bees and insects rest on the flowers, and the flowers will retract. Blooms to facilitate pollination by bees and other insects.
Similarly, the genes of this Venus flytrap are actually similar to those of Mimosa pudica, and we also hope to find the genes that control the plant's response to movement by comparing the genes in these motile plants."
After listening to Yang Fang's explanation, everyone finally understood. They didn't expect that such a dangerous and disgusting plant could be used in this way, and that the gene extracted from such a plant could be injected into flowers, allowing people to touch and bloom.
, this is so amazing. When I think of this, the fear, fear, and nausea in everyone's hearts disappear, and they can't help but fantasize about the flowers that will bloom in the future.
Wu Hao, on the other hand, smiled and nodded and said: "Continue!"
Yes! Yang Fang responded, and then went on to introduce: "In addition, we also hope to develop a specialized rodent trap and plant it in some areas where rodents are more serious.
For example, there were news reports a few days ago that a grassland in the Mongolian region was severely infested with rats, resulting in the destruction of a large amount of grassland and heavy losses to the herdsmen. Conventional rat hunting and eradication without bad words is difficult to work.
Chemical poisons can easily pollute the environment and cause damage to the ecological chain. Therefore, experts are also very worried about how to eliminate rodent infestations.
If we have rat-catching grass like ours, we can plant it in these grasslands with serious rat infestations, which can greatly curb rat infestations. More importantly, it is a biological rat-catching grass.
This method will not pollute the environment, nor will it affect other animals and people. It is very safe, efficient and cheap."
Hearing Yang Fang's words, Wu Hao couldn't help but frowned and looked at her and asked: "It's a good idea, but is it really feasible? Let's not talk about other things, but is this plant safe? Once it becomes like other invasive alien plants,
If it spreads wildly on the grasslands, it will be a huge disaster for the ecological environment of these areas.
It can hunt mice, which means it can hunt some small animals, such as rabbits, hedgehogs, minks, foxes, and some birds, which are the main components of the ecosystem.
In addition, is its gene stable? If it is unstable, it will also contaminate some surrounding grassland plants, thus causing a serious ecological crisis."
Hearing Wu Hao's words, Yang Fang smiled and replied: "First of all, let me answer your second question. Regarding the issue you are worried about, we are still in the process of conducting observation experiments and cannot obtain accurate experimental results yet.
.
But judging from the current series of observation experiments, its genes are relatively stable, and there will be no problems with gene expansion and gene contamination. Of course, this is only the current result, and everything is subject to the final experimental test results.
.
Then there is the first question. Your concerns are not unreasonable, and this is something we have always paid more attention to. To this end, we have also done a lot of work to try to minimize this threat, or directly eliminate it.
To prevent this kind of plant from spreading wildly, the simplest and most direct problem is to eliminate its reproductive ability, so that it cannot bear fruit, or the fruit it bears cannot mature or bud.
In addition, we must require that the branches and leaves of this kind of squirrel do not have the ability to be cut again. Whether it is natural causes that cause these plants to break and insert into the ground, or man-made causes and catalysis, they will not be able to take root and sprout.
In this way, we can greatly prevent the crazy spread of this kind of mousetrap after it is terminated."
After hearing what Yang Fang said, Shen Ning, who was standing behind Wu Hao, couldn't help but wonder: "It has no fruits and can't be cut. How can this kind of plant reproduce?"
"Haha, it's very simple, laboratory cultivation." Yang Fang replied with a smile: "Just like orchid cultivation, we only need to take out an embryo from the plant, then put it into the culture medium for cultivation, and wait until it grows up , and then removed for cultivation.”
