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

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

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

Oxidation of the C5'-position of DNA results in direct strand scission. The 3'-fragments produced contain DNA lesions at their 5'-termini. The major DNA lesion contains an aldehyde at its C5'-position, but its nucleobase is unmodified. Excision of the lesion formed
