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-uptake …

Iron uptake mechanisms in plants: functions of the FRO family of ferric reductases

J Jeong, EL Connolly - Plant science, 2009 - Elsevier
Iron is essential for plants and plays critical roles in important processes such as photosynthesis
and respiration. While our understanding of molecular mechanisms involved in iron …

[HTML][HTML] Iron stress in plants

EL Connolly, ML Guerinot - Genome biology, 2002 - Springer
Although iron is an essential nutrient for plants, its accumulation within cells can be toxic.
Plants, therefore, respond to both iron deficiency and iron excess by inducing expression of …

A ferric-chelate reductase for iron uptake from soils

NJ Robinson, CM Procter, EL Connolly, ML Guerinot - Nature, 1999 - nature.com
Iron deficiency afflicts more than three billion people worldwide 1 , and plants are the principal
source of iron in most diets. Low availability of iron often limits plant growth because iron …

Expression of the IRT1 metal transporter is controlled by metals at the levels of transcript and protein accumulation

EL Connolly, JP Fett, ML Guerinot - The Plant Cell, 2002 - academic.oup.com
Iron, an essential nutrient, is not readily available to plants because of its low solubility. In
addition, iron is toxic in excess, catalyzing the formation of hydroxyl radicals that can damage …

Overexpression of the FRO2 ferric chelate reductase confers tolerance to growth on low iron and uncovers posttranscriptional control

EL Connolly, NH Campbell, N Grotz… - Plant …, 2003 - academic.oup.com
The Arabidopsis FRO2 gene encodes the low-iron-inducible ferric chelate reductase responsible
for reduction of iron at the root surface. Here, we report that FRO2 and IRT1, the major …

Transcriptome Sequencing Identifies SPL7-Regulated Copper Acquisition Genes FRO4/FRO5 and the Copper Dependence of Iron Homeostasis in Arabidopsis

…, SC Dodani, M Pellegrini, P Huijser, EL Connolly… - The Plant …, 2012 - academic.oup.com
The transition metal copper (Cu) is essential for all living organisms but is toxic when present
in excess. To identify Cu deficiency responses comprehensively, we conducted genome-…

[HTML][HTML] The EAR-motif of the Cys2/His2-type zinc finger protein Zat7 plays a key role in the defense response of Arabidopsis to salinity stress

…, MW Lewis, D Warren, J Cushman, EL Connolly… - Journal of Biological …, 2007 - ASBMB
Cys2/His2-type zinc finger proteins, which contain the EAR transcriptional repressor domain,
are thought to play a key role in regulating the defense response of plants to biotic and …

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 …

Chloroplast Fe (III) chelate reductase activity is essential for seedling viability under iron limiting conditions

…, L Kerkeb, M Pilon, EL Connolly… - Proceedings of the …, 2008 - National Acad Sciences
Photosynthesis, heme biosynthesis, and Fe-S cluster assembly all take place in the chloroplast,
and all require iron. Reduction of iron via a membrane-bound Fe(III) chelate reductase is …
