Study on the Pigment Formation Mechanism of Macrobrachium rosenbergii
Macrobrachium rosenbergii is an important economic shrimp in China, because of its large size, fast growth, wide feeding, easy cultivation and high breeding efficiency.In recent years, the aquaculture industry of Macrobrachium rosenbergii in China has developed rapidly.At present, the aquaculture industry of Macrobrachium rosenbergii in China is in a key stage of transformation from "quantity" to "quality", and it is urgent to improve the quality of Macrobrachium rosenbergii through technical research.The highest content of carotenoids in the tissue of Macrobrachium rosenbergii is astaxanthin.Astaxanthin is a kind of ketone carrot with coloring, antioxidant, health care and other functions, which is widely used in aquaculture, food, cosmetics, health care, pharmaceutical and other industries.Astaxanthin has excellent coloring ability, astaxanthin also has strong antioxidant activity. In addition, astaxanthin has significant effects on physical and mental health and treatment of diseases such as hypertension, cancer, heart disease, ischemia, and neurological diseases. Astaxanthin has been listed as the best prevention and treatment drug for a variety of acute or chronic diseases.Therefore, astaxanthin has high nutritional and medicinal value.On the basis of in-depth understanding of the research progress of color formation and carotenoid accumulation of crustaceans at home and abroad, this project will further understand the mechanism of color formation of Macrobrachium rosenbergii through transcriptome.
