After listening to Yang Fang's introduction, Wu Hao smiled and nodded: "Very good. As people's material lives continue to improve, everyone has higher requirements for spiritual life, and our country's flower consumption market has also
is constantly expanding.
However, compared with other countries, the varieties of our domestic flower market are relatively single, which is quite different from foreign countries, especially developed countries such as the West. Moreover, many flower varieties do not have their own independent intellectual property rights and are controlled by others.
This is true. Don’t think that just a flower has its own intellectual property rights and can be controlled by others.
In fact, this is true. Take the roses that everyone likes for example. Almost all the rose varieties we are familiar with come from overseas. Many of them have their own intellectual property rights, and our domestic companies want to introduce them.
If so, you will have to pay a large license fee.
Therefore, cultivating flower varieties with our own independent property rights will have a great positive effect on our country's fight against the invasion of these foreign flower giants.
And in terms of market revenue, with these excellent varieties of flowers and ornamental plants, we can also make great achievements in this market."
Having said this, Wu Hao turned to Yang Fang and said, "Don't worry and go ahead. I will continue to pay attention to you in this regard."
Thank you, Mr. Wu. Yang Fang smiled happily when she heard this.
Well, Wu Hao smiled and nodded, then looked at the other flowers and plants and said with a smile: "Tell us more about these new varieties."
Okay. Yang Fang nodded with a smile and then led Wu Hao and the others to a special plant. Then she smiled at everyone and said, "This is a very interesting ornamental plant we cultivated. Don't look at it.
It looks a little unremarkable, but it's actually a very beautiful plant, we call it a color-changing tree."
Color-changing tree? Everyone couldn't help but be surprised after hearing Yang Fang's words. Color-changing tree, did you realize that this tree can change color, is it the same as a chameleon?
Faced with everyone's confused expressions, Yang Fang smiled and took a transparent tablet from her assistant, then slid it a few times to connect to the vertical display screen closest to them, and then introduced it to everyone.
"Actually, it is just as everyone thinks, a color-changing tree. As the name suggests, this tree can change color. We extracted, mixed and edited the genes of many kinds of plants, and finally cultivated such a color-changing tree.
There is not much difference between the appearance of ordinary trees and ordinary trees. However, the color of leaves will change into different colors according to their growth cycle, temperature and humidity.
First, when the leaves just sprout, they are bright yellow. The leaves gradually grow up and turn golden yellow, and then turn into deep yellow, orange, orange-red, red, crimson, purple, and blue. Then the pigment gradually fades away.
It turned green, then turned brown and withered and fell.
What we see now is that it is in the transition period from dark red to purple, so it looks a little red and purple. In about a week or two, it will completely turn purple, and then turn a little bit blue.
.
This is a delayed video we made to record its color changes throughout the year. Please watch it on the big screen."
After hearing Yang Fang's words, everyone immediately followed her instructions and looked at the big screen. Suddenly the short film on the big screen began to play. A small tree that was not very big began to sprout tender yellow buds from its bare trunk.
.The new shoots gradually grew up and turned into a very conspicuous golden color, just like a golden tree covered with gold leaves.
Immediately afterwards, the leaves began to gradually deepen in color, from golden color to true color, then orange, orange-red. The color of the leaves deepened little by little, and then directly turned into bright red, which was very bright.
Immediately afterwards, the red began to slowly deepen, turning into a more textured deep red, a bit like the red of a rose, and more like a national red.
As the red reaches its extreme, the color of the leaves gradually begins to become a little purple, and turns into a very pleasing pink-purple. The purple gradually becomes more and more apparent, and the entire leaves also turn into a deep purple color.
Some are like the color of purple bamboo plum, or even more like the color of purple cabbage.
This kind of purple also makes this color-changing tree exude a slightly weird and mysterious aura, as if the whole body is exuding poisonous gas. Fortunately, this purple color does not last long, and soon the purple leaves slowly have
It started to turn blue, and the blue became thicker and thicker. Eventually, the leaves of the whole tree began to turn blue. This blue was like the blue of blueberries. It began to slowly degrade from dark blue to lake blue.
The sky is blue, and then the blue leaves start to slowly turn green, just like a real tree.
Unfortunately, this was only for a moment, and then the leaves began to turn a yellowish-brown color, and then slowly withered and fell.
So beautiful, how did you do it? Zhang Jun looked at the picture on the big screen and asked involuntarily.
"Haha, it means to extract the color-related genes from plants of different colors in nature, and then select a basic tree for implantation and editing. Eliminate the original part of the genes of this tree, and then use these extracted different colors
Genes are implanted. And through gene editing of plants, the changes in leaf color of trees at different stages are controlled, and then a triggering mechanism is set.
For example, changes in temperature, humidity, light, etc. Plants sense changes in these external factors and make corresponding changes." Yang Fang explained with a smile.
As for Wu Hao, he raised his own question at this time: "Then how can we maintain a constant state? Will this color-changing tree maintain a specific color?"
After hearing Wu Hao's words, everyone else nodded and looked at Yang Fang. They also had questions in this regard.
Yang Fang smiled and shook her head: "Actually, the impact is not big. We have not changed the original growth genes of the trees, so even if they grow in a constant environment, the trees will still sprout, grow and then dry up."
fallen leaves.
During this growth process, the leaves will still change color according to the implanted color-changing genes. However, without the influence of these external factors, such as changes in temperature, humidity, and light, the color change will be less obvious and not so bright.
Because our basic mother tree is a plant that grows in a climate zone with four distinct seasons, if it is placed in such a constant environment to grow, it will not grow well without climate change. This is just like some plants that like sunlight.
Some like the shade, some are drought-tolerant, and some like water."
