Biofortification is a new health strategy aimed at preventing iron and micronutrient shortages in staple food crops by increasing their concentration and nutritional quality. Understanding the uptake, transit, and outflow of essential elements in rice is crucial for increasing iron and other nutrients in the endosperm. The study utilized various genes to enhance iron storage, transport, translocation, uptake, and translocation in white grains, including soyferH1, OsNAS1, OsYSL2, IDS3, and OsVIT1. AtNRAMP1, AtNRAMP3, and AtNRAMP4 are involved in the transport of iron and cadmium in Arabidopsis, with AtNRAMP1 being primarily expressed in roots. The expression of two transgenes, nicotianamine synthase and ferritin, in the rice endosperm of Japonica rice and other cultivars has led to a significant increase in iron content.
