Function Of Iron

First of all, iron is involved when a plant produces chlorophyll, which gives the plant oxygen as well as its healthy green color. This is why plants with an iron deficiency, or chlorosis, show a sickly yellow color to their leaves. Iron is also necessary for some enzyme functions in many plants. Soil that is alkaline or has had too much lime ...

Iron dynamics in the rhizosphere as a case study for analyzing

Iron is an essential element for plants and microbes. However, in most cultivated soils, the concentration of iron available for these living organisms is very low because its solubility is controlled by stable hydroxides, oxyhydroxides and oxides. In the rhizosphere, there is a high demand of iron because of the iron uptake by plants, and …

The Adaptive Mechanism of Plants to Iron Deficiency via Iron Uptake

Iron is an essential element for plant growth and development. While abundant in soil, the available Fe in soil is limited. In this regard, plants have evolved a series of mechanisms for efficient iron uptake, allowing plants to better adapt to iron deficient conditions.

Iron transport and its regulation in plants

Plants take up iron from soil in which iron solubility is extremely low especially under aerobic conditions at high-pH range. Therefore, plants have evolved efficient iron-uptake mechanisms. Because iron is prone to being precipitated and excess ionic iron is cytotoxic, plants also have sophisticated internal iron-transport mechanisms.

ENH1287/EP551: Iron for Florida Turfgrasses

Iron makes up about 5% of the earth's crust, but most of this Fe is unavailable for plant uptake because it is bound in primary or secondary minerals such as goethite and hematite (Havlin et al. 1999). Compared with other cations in the soil solution, soluble Fe is usually very low and is commonly lower than necessary to meet plant requirements.
