摘要：

In nongraminaceous plants, the Fe-II-transporter gene and ferric-chelate reductase gene have been cloned from Arabidopsis thaliana, whereas Fe-III-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 Fe-III-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.
