WebNov 20, 2024 · Photosystems are rich in Fe-containing proteins and represent the strongest sink for iron in plants. It appears that sensing of iron deficiency occurs fastest in the leaf vasculature (Khan et al. 2024), suggesting that perception of iron deficiency in sink organs and systemic signaling constitute early factors in the regulation of root iron uptake. WebIn plants and algae, iron-sulfur cluster assembly pathways of bacterial origin are localized in the mitochondria and plastids, where there is a high demand for these cofactors. A third iron-sulfur cluster assembly pathway is present in the cytosol that depends on the mitochondria but not on plastid assembly proteins. citizens bank of mukwonago east troy wi
