摘要: Since folic acid (FA) was officially recommended in 1998, concerns have emerged about the effect of excess FA intake, in particular with respect to negative clinical effects. Given this, a high-folate corn inbred line that we identified from a global germplasm collection was believed to become a valid alternative to FA supplementation. In this study, we proved this natural form of plant-sourced folates exhibited an effective restoration of folate deficiency. Folate metabolism and methylation modifications were restored in folate-deficient mice with folate-supplemented diets in 4 weeks. Restoration effects varies depending on folate sources, restricted retrotransposon activity and an orderly pattern of phospholipid/lipid metabolism protected by this high-folate corn partly en-sures a healthy folate status for development. Totally, we proved in mice models that this kind of folate bio-fortification corn could provide a valid alternation of FA supplementation in alleviation of folate deficiency during pregnancy.
