Scientists identify a plant molecule that sops up iron-rich heme

A new study reveals that a peptide produced by some legumes helps them control nitrogen-fixing bacteria by sequestering all available heme, an iron-containing molecule. This sends the bacteria into an iron-starvation mode that ramps up their production of ammonia, the form of nitrogen that is usable for plants.
