SL353/SS555: Iron (Fe) Nutrition of Plants

Iron is a required plant nutrient for normal plant growth and reproduction. Iron is required in small amounts and is called a "micronutrient." Iron is a challenging plant nutrient to work with because of its reactions in the soil and its plant physiology. Iron is typically highly insoluble in the soil used for most plant production systems.

Cast Iron Plant Care - Tips For Growing Cast Iron Plants

The cast iron plant (Aspidistra elatior), also known as iron plant and ballroom plant, is an extremely hardy houseplant and a perennial favorite in some regions.Growing cast iron plants is especially favored by those who don't have a lot of time for plant care, as this species can survive even the most extreme conditions where other plants would shrivel and …

Getting to the root of plant iron uptake and cell-cell ...

The mechanisms of iron nutrition in plants share similarities with the well-known absorption and transport of iron in mammals. In enterocytes, DIVALENT METAL TRANSPORTER 1 (DMT1) is the major iron influx transporter driving dietary iron absorption from the lumen of the duodenum. 15 DMT1 is polarized at the apical domain of the enterocyte. 15 …

IRT1, an Arabidopsis Transporter Essential for Iron Uptake ...

Among the known broad-range plant metal transporters, three families, NRAMP, YSL, and ZIP, may be involved in iron transport. Members of the Arabidopsis NRAMP family have been shown to be involved in iron homeostasis ( Curie et al., 2000 ; Thomine et al., 2000 ); however, their physiological role in the plant remains unclear.

Iron Transport and Signaling in Plants | SpringerLink

Paradoxically, although iron is abundant in many soils, iron availability is very often limiting for plant growth. In addition, iron is potentially highly toxic to cells. Therefore, iron homeostasis needs to be tightly regulated. This chapter focuses on the iron transport pathways dedicated to iron uptake, distribution and sequestration in ...

Iron transport and its regulation in plants - ScienceDirect

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 mediated by cellular sensing and long-distance signaling. Abstract

Mechanism of Zinc absorption in plants: uptake, transport ...

Earlier discovery on VITs addresses their role in iron trafficking from cytosol to vacuole, but later on their function in transport of other micronutrients (Zn and Mn) has been identified. Functional divergence has been found in VIT orthologs of different plant species (Kim et al. 2006 ; Momonoi et al. 2009 ).

Mining iron: iron uptake and transport in plants

Iron uptake in plants is highly regulated in order to supply amounts sufficient for optimal growth while preventing excess accumulation. In response to iron deficiency, plants induce either reduction-based or chelation-based mechanisms to enhance iron uptake from the soil. Genes involved in each mec …

Mining iron: Iron uptake and transport in plants ...

Genes involved in each mechanism have been identified from various model plants including Arabidopsis and rice. Iron transport within plants is also tightly controlled. New information has emerged on transporters that play a role in xylem loading and phloem loading/unloading of iron, and on the iron chelators involved in iron homeostasis.

Iron uptake, translocation, and regulation in higher plants

Key molecular components-including transporters, enzymes, and chelators-have been clarified for both strategies, and many of these components are now thought to also function inside the plant to facilitate internal iron transport. Transporters for intracellular iron …

Despite great leaps forward in the research into plant iron nutrition over the past decades, many facets of cellular iron homeostasis still await further clarification. Moreover, attempts to increase the iron content in edible plant parts are far from having reached sufficient improvement in dietary iron intake.

A. Nonintestinal iron transport by transferrin. All cells require iron to maintain normal function. In nonintestinal cells, circulating iron is bound to transferrin (Tf) and is imported via receptor-mediated endocytosis after binding to the transferrin receptor (TfR) ().Because Tf and TfR are absent from enterocytes, Tf binds iron and plays an essential role in the transport of iron …

After iron has been taken up from the soil by plant roots, it has to be distributed to plant tissues and organs by long distance transport. Within plant cells, the quantitatively most important sites for iron use are chloroplasts and mitochondria [ 16 ]. Chloroplast Fe accounts for 70–90% of cellular iron in mesophyll cells [ 16 ].
