Universities breeding "thorns" Wuchang fish follow -up, X -ray comparison chart comes

In 2021, the team of Huazhong Agricultural University announced

Find the control of the fishbone gene

It is expected to realize the news of eating fish without stabbing

The school Gao Zexia team

Breeding out of no muscle thorns at all

Wuchang Fish (Tu Toutou) seedlings

It is expected to promote large -scale!

Since the beginning of this year, they have used the first -generation miscellaneous composition (F0 generation) less stabbing fish, and have been breeded by the mate with the mate with the mate with the Wuchang fish (F1 generation) of Wuchang fish (F1 generation). Carry out the genetic stable breeding work. According to normal procedures, after the new type of quality is stable, the relevant certification of the country can be obtained, and it can be promoted on a large scale.

Look directly at the comparison chart

It can be seen from the displayed picture that a 51.1 gram of thorns Wuchang fish is almost different from the same length compared to the same length.

In X -light, you can see their obvious differences. There are small spines that grow horizontally in the body of Wuchang fish in the body of Wuchang fish, and the light of the muscle is shiny under the light. Instead.

The skeletal dyeing picture clearly shows the contrast of the fishbone. There are skeleton with martial arts and spines, and the lines appear dense, but there is no thorns Wuchang fish skeleton comfortable, without any extra small thorns.

Gao Zexia said that the thorns -free Wuchang fish they breed this year are good, and more testing is currently underway.

It is reported that thorns -free fish is not only achieved on Wuchang fish, but some experts also report on the test and application of different fish after the introduction of the primary effect gene found by the Gao Zexia team. After regulating the main effect gene of the growth of fishbone, the latest gene knockout has also been achieved on the catfish. The F0 generation of ray fish is obtained, and the muscle spines will decrease by 50%. According to the current R & D speed, it is expected that in the near future we can eat no assassin fish.
