Shanghai Ocean University explains the molecular mechanism of fish visual gene duplication |
How can the Sumei fish walking through the corals find their favorite "object" in the school of fish, and then "court" and get married? Growing up near the coast, how can it adapt to different light and forage in coral reefs? Recently, the team of Professor Tang Wenqiao of Shanghai Ocean University has used the corrugated lip fish as the research object to explain the molecular mechanism of fish visual gene duplication for the first time in the world.
The scientific name of Sumei is a large coral reef fish with bright body color, sexual reversal, female first maturity and male-male mating behavior.
In this study, scientists discovered that the wavy-lipped fish lost some visual genes, but some other visual genes were duplicated.
The wild population of the corrugated lip fish is rare, and it is the second-level key protected wildlife of China, and it is also listed as an endangered animal by the World Conservation Union.
Tang Wenqiao said that the next step for the research team will carry out research on the evolution of the body shape of the corrugated lip fish to further reveal the secrets of their growth.
