Molecular plant-microbe interactions : MPMI, 32(10), 1324-1335 (2019-05-21)
In ascomycetes and basidiomycetes, iron-responsive GATA-type transcriptional repressors are involved in regulating iron homeostasis, notably to prevent iron toxicity through control of iron uptake. To date, it has been unknown whether this iron regulator contributes toward mutualistic endosymbiosis of microbes

Food and nutrition bulletin, 33(2), 111-116 (2012-08-23)
Ferric sodium ethylenediaminetetraacetate (NaFeEDTA) enhances iron absorption in the presence of phytate. However, the amount of NaFeEDTA that would have to be added to a complementary food to provide the necessary intake of iron for an infant or young child

To assess the effectiveness of social mobilization and social marketing in promoting NaFeEDTA-fortified soy sauce in an iron deficient population. This study was an uncontrolled, community-based, before-after study, which was implemented in three counties of Shijiazhuang Municipality. The intervention was

Cowpeas, like other legumes, contain high amounts of native iron but are rich in phytic acid (PA) and polyphenols (PP) that inhibit iron absorption. NaFeEDTA may overcome the combined inhibitory effect of PA and PP. Our objective was to test
