Description

technical field

[0001] The invention belongs to the field of biotechnology; more specifically, the invention relates to a metal transporter, its encoding gene and its use. Background technique

[0002] Iron is an essential trace element for the human body. Iron deficiency can lead to various diseases in the human body. The most common and most harmful one is iron deficiency anemia. Iron deficiency anemia is recognized in the world as one of the four major nutritional deficiency diseases that are more serious and widespread. According to statistics, about 3 billion people in the world are iron deficient, and the incidence of anemia caused by iron deficiency is as high as 30% of the world's total population (http: / / www.who.iht / nutrition / topics / ida / ), of which People in developing countries are most severely deficient in iron. One of the main reasons is that people in developing countries generally eat cereals as their staple food, but the iron content in cereals is low, and ...
