　　According to foreign media reports, scientists are now able to steal genes from seaweed swallowed by bright green turtles. These seaweeds have the function of "photosynthesis" and can extract energy from the sun's rays like plants.

　　is called "green leaf sea cucumber", it integrates seaweed genes into its own chromosomes to achieve photosynthesis. In this process, green leaf sea cucumbers can use solar energy to convert carbon dioxide and water into nutrients for photosynthesis. Researchers believe that this method of hijacking other biological genes is likely to be used to establish new treatments for human genetic diseases. Sidney Pierce, a biologist at the University of South Florida and the University of Maryland, said that no animal on earth can steal the Chlorella gene and fuse it with its own cells, but it can fuse with green leaves.

　　Kanokai slugs rely on sunlight for nutrients, so even if there is a problem with the food source, as long as more green algae can be swallowed, they will not starve to death. This study of natural gene transduction mechanisms can be used to develop a new generation of medical applications. With a deep understanding of how sea turtles use the Chlorella gene, in the future, medical experts will be able to obtain the gene from other organisms and treat certain human diseases.

　　Oobakai slugs live in shallow pools and salt marshes on the east coast of the United States. It is usually reddish brown when it is young, but it turns bright green when eating seaweed.

　　In the 1970s, scientists began to study and pay attention to green-leaf turtles, which can combine seaweed chloroplasts with their cells and turn them into bright green. Chloroplasts are small organelles found in green leaves that can collect sunlight to perform chemical reactions to provide energy for the survival of plants.

　　Sea urchins eat sea urchins from the sea and transplant the genes of this seaweed into the cells of their digestive system. You can then use these chloroplasts to make carbohydrates and lipids. Lasts for 9 months.

　　But scientists don’t know how Green Leaf Sea Cucumber can maintain chlorophyll for a long time without cells or phytonutrients. Pierce and his colleagues analyzed Hai’s DNA and found that Hai’s genes can be combined with his own chromosomes. .. This gene is used to repair chloroplast damage and maintain its function. The gene binds to the sea cucumber chromosome and inherits this ability in the next generation of sea cucumbers.
