Flavins secreted by roots of iron‐deficient Beta vulgaris enable mining of ferric oxide via reductive mechanisms

P Sisó‐Terraza, JJ Rios, J Abadía, A Abadía… - New …, 2016 - Wiley Online Library
Iron (Fe) is abundant in soils but generally poorly soluble. Plants, with the exception of
Graminaceae, take up Fe using an Fe (III)‐chelate reductase coupled to an Fe (II) …

The multiple facets of root iron reduction

L Grillet, W Schmidt - Journal of Experimental Botany, 2017 - academic.oup.com
The biological significance of iron (Fe) is based on its propensity to oscillate between the
ferric and ferrous forms, a transition that also affects its phyto-availability in soils. With the …

New routes for plant iron mining

C Curie, S Mari - New Phytologist, 2017 - Wiley Online Library
Plant iron (Fe) uptake relies to a large extent on the capacity of cells to control and extract Fe
pools safely conserved in extracytoplasmic environments such as the apoplast and …

Mechanisms and regulation of reduction-based iron uptake in plants

W Schmidt - The New Phytologist, 1999 - cambridge.org
Despite the usually high abundance of iron (Fe) in soils, the low solubility of Fe-bearing
minerals restricts the available Fe pools in most aerobic soils to levels that are far below …

Reduction-based iron uptake revisited: on the role of secreted iron-binding compounds

J Rodríguez-Celma, W Schmidt - Plant signaling & behavior, 2013 - Taylor & Francis
With the exception of the grasses, plants rely on a reduction-based iron (Fe) uptake system
that is compromised by high soil pH, leading to severe chlorosis and reduced yield in crop …

[HTML][HTML] Iron nutrition in plants: towards a new paradigm?

M Li, S Watanabe, F Gao, C Dubos - Plants, 2023 - mdpi.com
Iron (Fe) is an essential micronutrient for plant growth and development. Fe availability
affects crops' productivity and the quality of their derived products and thus human nutrition …

Genetic evidence that induction of root Fe(III) chelate reductase activity is necessary for iron uptake under iron deficiency

Y Yi, ML Guerinot - The Plant Journal, 1996 - Wiley Online Library
Reduction of Fe (III) to Fe (II) by Fe (III) chelate reductase is thought to be an obligatory step
in iron uptake as well as the primary factor in making iron available for absorption by all …

Mutually Exclusive Alterations in Secondary Metabolism Are Critical for the Uptake of Insoluble Iron Compounds by Arabidopsis and Medicago truncatula

J Rodríguez-Celma, WD Lin, GM Fu, J Abadía… - Plant …, 2013 - academic.oup.com
The generally low bioavailability of iron in aerobic soil systems forced plants to evolve
sophisticated genetic strategies to improve the acquisition of iron from sparingly soluble and …

Iron acquisition by plants

S Mori - Current opinion in plant biology, 1999 - Elsevier
In nongraminaceous plants, the FeII-transporter gene and ferric-chelate reductase gene
have been cloned from Arabidopsis thaliana, whereas FeIII-reductase has not. In …

Complexity of iron nutrition: Lessons for plant‐soil interaction research

RL Chaney, PF Bell - Journal of plant nutrition, 1987 - Taylor & Francis
Iron deficiency chlorosis remains an economically important plant nutrition problem after
decades of research. However, basic research on Fe nutrition has provided much …
