Iron acquisition by plants

Curr Opin Plant Biol. 1999 Jun;2(3):250-3. doi: 10.1016/S1369-5266(99)80043-0.


In nongraminaceous plants, the FeII-transporter gene and ferric-chelate reductase gene have been cloned from Arabidopsis thaliana, whereas FeIII-reductase has not. In graminaceous monocots, the genes for mugineic acids (MAs) synthesis, nas (nicotianamine synthase) and naat (nicotianamine aminotransferase), have been cloned from barley, whereas the FeIII-MAs transporter gene is yet to be cloned. Transferrin absorption in Dunaliella has been reported, suggesting a phagocytotic (endocytotic) Fe-acquisition mechanism. Work to develop transgenic cultivars tolerant to Fe-deficiency in calcareous soils is now in progress.
