Key Genes for Lutein Synthesis and Prospects for Research on Wheat Bio-fortification
More than 2.2 billion people are disturbed by vision disorders in the world.People's health of vision is facing new threats.Lutein is the yellow pigment which is the main pigment of the retina,with the function of filter-ing blue light and improving immunity.It is the most effective and potential dietary supplement to protect vision.Human of the north mainly feed on wheat.Lutein wheat provide lutein when we eat it,so that human don't need additional expense on supplements.At the same time,bioaugmentation is also an important method to solve the problem of micronutrient deficiency.Therefore,it is very important to select lutein wheat varieties and improve the content of lutein in wheat.The author reviewed the discovery,structure and function of lutein,the methods of lutein detection,key enzymes and genes of lutein synthesis and the breeding of lutein wheat,in addition,discussed the problems and development trend of wheat lutein bioaugmentation.It provides reference for the development of lutein wheat industry in the future.It promotes the high-quality development of agriculture.
