Since the 1970s, transgenic technology has emerged as a groundbreaking field in biotechnology, attracting significant attention and investment worldwide. As reported in numerous scientific studies, over 20 countries and regions have actively engaged in research on genetic modification. This progress has led to the development of various techniques for fish transgenic technology, each with its own advantages and applications. In general, there are ten commonly used methods: 1. Microinjection, which includes oocyte nuclear injection and fertilized egg cytoplasm injection; 2. Electric pulse method; 3. Sperm carrier introduction; 4. Transcription-based methods; 5. Calcium phosphate coprecipitation; 6. Liposome fusion technique; 7. DEAE-dextran method; 8. Chromosomal fragment microinjection; 9. Germ stem cell-mediated transfer; and 10. Particle bombardment or microbomb methods.
As science continues to advance, new techniques are constantly being developed, leading to improvements in existing methods and the emergence of innovative approaches. These developments are expected to enhance the efficiency, precision, and safety of transgenic technologies. In the coming years, we can anticipate the creation of more advanced biotechnological tools that will enable the production of genetically modified organisms with improved traits, such as disease resistance, faster growth, and better adaptability. Such innovations will not only benefit scientific research but also contribute significantly to agriculture, aquaculture, and even human health, ultimately serving the greater good of society.
Anthocyanidins is a kind of water-soluble natural pigments widely existing in plants in nature. They are colored aglycone obtained from the hydrolysis of anthocyanins. Most of the main colorants in fruits, vegetables and flowers are related to them. Under the condition of different PH value of plant cell vacuoles, anthocyanidins make the petals colorful. The main functions about anthocyanidins are antioxidant and free radical scavenging function, nutritional fortifier in food and Natural Pigment.
