Subcellular dynamics studies of iron reveal how tissue‐specific distribution patterns are established in developing wheat grains

Abstract

 Understanding the mechanisms of iron trafficking in plants is key to enhancing the nutritional quality of crops. Because it is difficult to image iron in transit, we currently have an incomplete picture of the route(s) of iron translocation in developing seeds and how the tissue-specific distribution is established.  We have used a novel approach, combining 57 Fe isotope labelling and Nanoscale Secondary Ion Mass Spectrometry (NanoSIMS), to visualize iron translocation between tissues and within cells in im…
