Hydroponically grown corn (Zea mays) is highly susceptible to Fe-chlorosis. Iron (Fe) is essential for chlorophyll synthesis. Metals bound to chelates have reduced bioavailability (activity) compared to free ions.
Optimal Copper Supply Is Required For Normal Plant Iron Deficiency Responses, Brian M. Waters, Laura C. Armbrust
Optimal Copper Supply Is Required For Normal Plant Iron Deficiency Responses, Brian M. Waters, Laura C. Armbrust
Department of Agronomy and Horticulture: Faculty Publications
Iron (Fe) and copper (Cu) homeostasis are tightly linked across biology. Understanding crosstalk between Fe and Cu nutrition could lead to strategies for improved growth on soils with low or excess metals, with implications for agriculture and phytoremediation. Here, we show that Cu and Fe nutrition interact to increase or decrease Fe and/or Cu accumulation in leaves and Fe uptake processes. Leaf Cu concentration increased under low Fe supply, while high Cu lowered leaf Fe concentration. Ferric reductase activity, an indicator of Fe demand, was inhibited at insufficient or high Cu supply. Surprisingly, plants grown without Fe were more susceptible …

Wheat (Triticum Aestivum) Nam Proteins Regulate The Translocation Of Iron, Zinc, And Nitrogen Compounds From Vegetative Tissues To Grain, Brian M. Waters, Cristobal Uauy, Jorge Dubcovsky, Michael A. Grusak
Department of Agronomy and Horticulture: Faculty Publications
The NAM-B1 gene is a NAC transcription factor that affects grain nutrient concentrations in wheat (Triticum aestivum). An RNAi line with reduced expression of NAM genes has lower grain protein, iron (Fe), and zinc (Zn) concentrations. To determine whether decreased remobilization, lower plant uptake, or decreased partitioning to grain are responsible for this phenotype, mineral dynamics were quantified in wheat tissues throughout grain development. Control and RNAi wheat were grown in potting mix and hydroponics. Mineral (Ca, Cu, Fe, K, Mg, Mn, P, S, and Zn) and nitrogen (N) contents of organs were determined at regular intervals to …

Ethylene Involvement In The Regulation Of The H+-Atpase Csha1 Gene And Of The New Isolated Ferric Reductase Csfro1 And Iron Transporter Csirt1 Genes In Cucumber Plants, Brian M. Waters, Carlos Lucena, Francisco J. Romera, Gena G. Jester, April N. Wynn, Carmen L. Rojas, Esteban Alcántara, Rafael Pérez-Vicente
Department of Agronomy and Horticulture: Faculty Publications
In previous works using ethylene inhibitors and precursors, it has been shown that ethylene participates in the regulation of several Fe-deficiency stress responses by Strategy I plants, such as enhanced ferric reductase activity, rhizosphere acidification, and subapical root hair development. Furthermore, recent evidence suggests that ethylene could regulate the expression of both the ferric reductase and the iron transporter genes of Strategy I plants by affecting the FER (or FER-like) transcription factor. Recently, two H+-ATPase genes have been isolated from cucumber roots, CsHA1 and CsHA2. CsHA1 is up-regulated under Fe deficiency while CsHA2 is constitutively expressed. In …
Ethylene Could Influence Ferric Reductase, Iron Transporter, And H+-Atpase Gene Expression By Affecting Fer (Or Fer-Like) Gene Activity, Carlos Lucera, Brian M. Waters, Francisco Javier Romera, María José García, María Morales, Esteban Alcántara, Rafael Pérez-Vicente
Ethylene Could Influence Ferric Reductase, Iron Transporter, And H+-Atpase Gene Expression By Affecting Fer (Or Fer-Like) Gene Activity, Carlos Lucera, Brian M. Waters, Francisco Javier Romera, María José García, María Morales, Esteban Alcántara, Rafael Pérez-Vicente
Department of Agronomy and Horticulture: Faculty Publications
In previous works, it has been shown, by using ethylene inhibitors and precursors, that ethylene could participate in the regulation of the enhanced ferric reductase activity of Fe-deficient Strategy I plants. However, it was not known whether ethylene regulates the ferric reductase gene expression or other aspects related to this activity. This paper is a study of the effects of ethylene inhibitors and precursors on the expression of the genes encoding the ferric reductases and iron transporters of Arabidopsis thaliana (FRO2 and IRT1) and Lycopersicon esculentum (= Solanum lycopersicum) (FRO1 and IRT1) plants. The effects …

G82-596 Use And Management Of Micronutrient Fertilizers In Nebraska, George W. Rehm, E.J. Penas
G82-596 Use And Management Of Micronutrient Fertilizers In Nebraska, George W. Rehm, E.J. Penas
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide focuses on the use of the micronutrients zinc and iron.
Of the 16 elements known to be essential for plant growth, 7 are used in very small amounts and are classified as micronutrients. These are zinc (Zn), iron (Fe), manganese (Mn), copper (Cu), boron (B), molybdenum (Mo) and chlorine (Cl).
Micronutrients are supplied to plants from two sources: 1) soil minerals and 2) organic matter. They are released as the soil minerals break down over a period of time by weathering. The major portion of the micronutrients made available to plants, however, probably comes from the breakdown (mineralization) …
