Proper transport of metal and their homeostasis is very crucial for the growth and development of plants. Plants root are the primary organs which comes in contact with the stress and thus few modifications occurs, often determining the nutrient efficiency or sometimes as a stress tolerance mechanism. Plant utilizes two strategies for the uptake of iron viz, strategy I-reduction based and strategy II-chelation based. In this review we attempted for a better understanding of how the chelators acts in the mechanism of iron uptake from soils to plants and how iron is distributed in the plants.
金属的恰当运输及其内稳态对植物的生长发育至关重要。植物根系是与胁迫接触的主要器官，因此会发生一些变化，这些变化常常决定养分效率，有时也是一种胁迫耐受机制。植物利用两种策略吸收铁，即策略I——基于还原作用的策略和策略II——基于螯合作用的策略。在本综述中，我们试图更好地理解螯合剂在铁从土壤到植物的吸收机制中是如何起作用的，以及铁在植物中是如何分布的。
