Iron (Fe) is an essential micronutrient for plant growth and development, but excessive iron uptake can cause iron toxicity, leading to damage to plant cell membranes, reduced growth, yield, and ...
In a new study, researchers report that artemesinin--a derivative of the wormwood plant--kills iron-enriched breast cancer cells but doesn't harm many healthy ones. Artemesinin's destructive properties are triggered by higher than normal levels of iron in cancer cells. Many experiments have found that artemesinin turns deadly in the presence of ...
During the past decade, many Vacuolar Iron Transporter (VIT) and VIT-Like (VTL) genes have been identified and shown to play important roles in iron homeostasis in different plants.
Iron is an important mineral that helps your body build vital red blood cells to transport oxygen throughout your body tissue with the help of hemoglobin. If your body does not have enough iron, you can suffer from fatigue, headaches and, in extreme cases, iron deficiency.
Iron transport in plant body is mediated by various transporter proteins. Plants respond to iron deficiency by transcription factors and ubiquitin ligases. Plant iron response is …
Organic compounds, such as plants, leaves, fruits, seeds, roots, and bark, which bind to copper, provide helpful tools for converting cancer-fighting agents from cancer-encouraging agents. Iron plays an important role in cancer and metastasis owing to its great progress in cancer cell survival. Tumor cells have a higher demand for iron (anemia).
Artemisinin can kill cancer cells, especially when it is bound to iron. As long ago as 2004, researchers at the University of Washington Professor Henry Lai and Dr Narendra P. Singh, ... Chlorophyll (plant iron) is the cheap way of providing the iron for the artemisinin to ultimately attack. When the artemisinin attacks the iron it causes free ...
There is a continuous arms race between pathogens and their host plants. Li et al. reveal that PR1 prevents entry of a fungal effector into plant cells from the apoplast that otherwise would ...
Iron plays a crucial role in biochemistry and is an essential micronutrient for plants and humans alike. Recent progress in the field has led to a better understanding of iron …

Iron is one of 16 vital elements necessary for plants to grow and be healthy. In the garden, Iron is an important micronutrient. Without Iron, plants can't produce chlorophyll, which gives them their healthy, green color. Iron is also responsible for moving oxygen throughout the plant. Read on to learn more.
Since ILR3 has recently been shown to play a role in iron homeostasis (Zhang et al, Plant Cell, 2015) and glucosinolate biosynthesis (Li et al, Plant Physiology, 2014) we collaborated with Dr. Daniel Kleibenstein at the University of California, Davis to further examine the potential cross talk between iron homeostasis and glucosinolate synthesis.
These mechanisms include iron acquisition from soil, iron transport from roots to shoots, and iron storage in cells. The mobilization of Fe in plants often occurs via chelating with phytosiderophores, citrate, …
Forms and Sources of Iron in Soils Iron occurs in concentrations of 7,000 to 500,000 mg kg-1 in soils, where it is present mainly in the insoluble Fe(III) (ferric, Fe 3+) form.Ferric ions hydrolyze readily to give Fe(OH) 2 +, Fe(OH) 3, and Fe(OH) 4-, with the combination of these three forms and the Fe 3+ ions being the totalsoluble inorganic iron, and the proportions of these forms …
Although iron is plentiful, it exists primarily in its insoluble form and is therefore not freely available to plants. Thus, complex strategies involving chelators, production of reductive agents, reductase activities, proton-mediated processes, specialized storage proteins, and others, act in concert to mobilize iron from the environment into the plant and within the plant.
Iron (Fe) is an essential micronutrient for all living organisms, including plants and their associated microbes ().Iron readily donates and accepts electrons, as it can exist in multiple oxidation states, particularly its ferric (Fe 3+) and ferrous forms (Fe 2+).Therefore, iron cofactors such as heme and Fe-sulfur clusters function in all primary metabolic processes, including …
Iron (Fe) is a ubiquitous redox-active element essential for most life. The formation of localized cell wall appositions, the oxidative burst and the production of pathogenesis-related proteins are hallmarks of plant defense responses. Here, we report that iron is a central mediator linking these th …
Introduction. Iron (Fe) is one of the most important transition metals in plants required for essential cell functions. The known oxidation states of Fe in biological environments range from Fe(II) to Fe(IV) (heme), the chemistry of which is multiplied by accessible spin states (for review, see Chen and Browne, 2018).In biological systems, Fe-dependent redox reactions …
Iron plays a key role in the formation of red blood cells and reactions occurring in the human body. Food is one of the best and safe options to prevent and cure iron deficiency anemia.
The phenomenon of heat stress leading to ferroptosis-like cell death has recently been observed in bacteria as well as plant cells. Despite recent findings, the evidence of ferroptosis, an iron-dependent cell death remains unknown in microalgae. The present study aimed to investigate if heat shock c …
IRON-REGULATED TRANSPORTER 1 (IRT1) is a central iron transporter responsible for the uptake of iron from the rhizosphere to root epidermal cells.
