Heavy metals induce iron deficiency responses at different hierarchic and regulatory levels

A Le¡ ková, RFH Giehl, A Hartmann… - Plant …, 2017 - academic.oup.com
In plants, the excess of several heavy metals mimics iron (Fe) deficiency-induced chlorosis,
indicating a disturbance in Fe homeostasis. To examine the level at which heavy metals …

Two iron-regulated cation transporters from tomato complement metal uptake-deficient yeast mutants

U Eckhardt, A Mas Marques, TJ Buckhout - Plant Molecular Biology, 2001 - Springer

Iron uptake and transport in plants: the good, the bad, and the ionome

J Morrissey, ML Guerinot - Chemical reviews, 2009 - ACS Publications
Fe is essential for plant growth. At the same time, Fe is highly reactive and toxic via the
Fenton reaction. Consequently, plants tightly control Fe homeostasis and react to Fe …

Time to pump iron: iron-deficiency-signaling mechanisms of higher plants

EL Walker, EL Connolly - Current opinion in plant biology, 2008 - Elsevier
Iron is an essential nutrient for plants, yet it often limits plant growth. On the contrary,
overaccumulation of iron within plant cells leads to oxidative stress. As a consequence, iron …

Requirement and functional redundancy of Ib subgroup bHLH proteins for iron deficiency responses and uptake in Arabidopsis thaliana

N Wang, Y Cui, Y Liu, H Fan, J Du, Z Huang, Y Yuan… - Molecular plant, 2013 - cell.com
The Ib subgroup of the bHLH gene family in Arabidopsis contains four members (AtbHLH38,
AtbHLH39, AtbHLH100, and AtbHLH101). AtbHLH38 and AtbHLH39 were previously …

Similarities and differences in iron homeostasis strategies between graminaceous and nongraminaceous plants

ZF Chao, DY Chao - New Phytologist, 2022 - Wiley Online Library
Iron (Fe) homeostasis is essential for both plant development and human nutrition. The

Cytokinins negatively regulate the root iron uptake machinery in Arabidopsis through a growth‐dependent pathway

M Séguéla, JF Briat, G Vert, C Curie - The Plant Journal, 2008 - Wiley Online Library
Plants display a number of biochemical and developmental responses to low iron
availability in order to increase iron uptake from the soil. The ferric‐chelate reductase FRO2 …

Iron-binding E3 ligase mediates iron response in plants by targeting basic helix-loop-helix transcription factors

D Selote, R Samira, A Matthiadis, JW Gillikin… - Plant …, 2015 - academic.oup.com
Iron uptake and metabolism are tightly regulated in both plants and animals. In Arabidopsis

Expression profiling of the Arabidopsis ferric chelate reductase (FRO) gene family reveals differential regulation by iron and copper

I Mukherjee, NH Campbell, JS Ash, EL Connolly - Planta, 2006 - Springer
The Arabidopsis FRO2 gene encodes the iron deficiency-inducible ferric chelate reductase
responsible for reduction of iron at the root surface; subsequent transport of iron across the …
