An iron-induced nitric oxide burst precedes ubiquitin-dependent protein degradation for Arabidopsis AtFer1 ferritin gene expression Inra
Arnaud, N .; Murgia, I.; Boucherez, J.; Briat, J.F.; Cellier, F.; Gaymard, F..
Ferritins play an essential role in iron homeostasis by sequestering iron in a bioavailable and non-toxic form. In plants, ferritin mRNAs are highly and quickly accumulated in response to iron overload. Such accumulation leads to a subsequent ferritin protein synthesis and iron storage, thus avoiding oxidative stress to take place. By combining pharmacological and imaging approaches in an Arabidopsis cell culture system, we have identified several elements in the signal transduction pathway leading to the increase of AtFer1 transcript level after iron treatment. Nitric oxide quickly accumulates in the plastids after iron treatment. This compound acts downstream of iron and upstream of a PP2A-type phosphatase to promote an increase of AtFer1 mRNA level. The...

Arabidopsis IRT2 cooperates with the high-affinity iron uptake system to maintain iron homeostasis in root epidermal cells Inra
Vert, G.; Barberon, M.; Zelazny, E.; Seguela, M.; Briat, J.F.; Curie, C..
Iron is an essential nutrient for all organisms but toxic when present in excess. Consequently, plants carefully regulate their iron uptake, dependent on the FRO2 ferric reductase and the IRT1 transporter, to control its homeostasis. Arabidopsis IRT2 gene, whose expression is induced in root epidermis upon iron deprivation, was shown to encode a functional iron/zinc transporter in yeast, and proposed to function in iron acquisition from the soil. In this study, we demonstrate that, unlike its close homolog IRT1, IRT2 is not involved in iron absorption from the soil since overexpression of IRT2 does not rescue the iron uptake defect of irt1-1 mutant and since a null irt2 mutant shows no chlorosis in low iron. Consistently, an IRT2-green fluorescent fusion...

Cytokinins negatively regulate the root iron uptake machinery in Arabidopsis through a growth-dependent pathway Inra
Seguela, M.; Briat, J.F.; Vert, G.; Curie, C..
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 and the ferrous iron transporter IRT1 control iron entry from the soil into the root epidermis. In Arabidopsis, expression of IRT1 and FRO2 is tightly controlled to maintain iron homeostasis, and involves local and long-distance signals, as well as transcriptional and post-transcriptional events. FIT encodes a putative basic helix-loop-helix (bHLH) transcription factor that regulates iron uptake responses in Arabidopsis. Here, we uncover a new regulation of the root iron uptake genes. We show that IRT1, FRO2 and FIT are repressed by the exogenous addition of cytokinins (CKs), and that...

Ferritins and iron storage in plants Inra
Briat, J.F.; Duc, C.; Ravet, K.; Gaymard, F..
Iron is essential for both plant productivity and nutritional quality. Improving plant iron content was attempted through genetic engineering of plants overexpressing ferritins. However, both the roles of these proteins in the plant physiology, and the mechanisms involved in the regulation of their expression are largely unknown. Although the structure of ferritins is highly conserved between plants and animals, their cellular localization differ. Furthermore, regulation of ferritin gene expression in response to iron excess occurs at the transcriptional level in plants, in contrast to animals which regulate ferritin expression at the translational level. In this review, our knowledge of the specific features of plant ferritins is presented, at the level...

Ferritins control interaction between iron homeostasis and oxidative stress in Arabidopsis Inra
Ravet, K.; Touraine, B.; Boucherez, J.; Briat, J.F.; Gaymard, F.; Cellier, F..
Ferritin protein nanocages are the main iron store in mammals. They have been predicted to fulfil the same function in plants but direct evidence was lacking. To address this, a loss-of-function approach was developed in Arabidopsis. We present evidence that ferritins do not constitute the major iron pool either in seeds for seedling development or in leaves for proper functioning of the photosynthetic apparatus. Loss of ferritins in vegetative and reproductive organs resulted in sensitivity to excess iron, as shown by reduced growth and strong defects in flower development. Furthermore, the absence of ferritin led to a strong deregulation of expression of several metal transporters genes in the stalk, over-accumulation of iron in reproductive organs, and...

High-affinity manganese uptake by NRAMP1 is essential for Arabidopsis growth in low manganese conditions Inra
Cailliatte, R.; Schikora, A.; Briat, J.F.; Mari, S.; Curie, C..
In contrast with many other essential metals, the mechanisms of Mn acquisition in higher eukaryotes are seldom studied and poorly understood. We show here that Arabidopsis thaliana relies on a high-affinity uptake system to acquire Mn from the soil in conditions of low Mn availability and that this activity is catalyzed by the divalent metal transporter NRAMP1 (for Natural Resistance Associated Macrophage Protein 1). The nramp1-1 loss-of-function mutant grows poorly, contains less Mn than the wild type, and fails to take up Mn in conditions of Mn limitation, thus demonstrating that NRAMP1 is the major high-affinity Mn transporter in Arabidopsis. Based on confocal microscopy observation of an NRAMP1-green fluorescent protein fusion, we established that...

Increased sensitivity to iron deficiency in Arabidopsis thaliana over-accumulating nicotianamine Inra
Cassin, G.; Mari, S.; Curie, C.; Briat, J.F.; Czernic, P..
Nicotianamine (NA) is a non-protein amino acid derivative synthesized from S-adenosyl L-methionine able to bindseveral metal ions such as iron, copper, manganese, zinc, or nickel. In plants, NA appears to be involved in ironavailability and is essential for the plant to complete its biological cycle. In graminaceous plants, NA is also theprecursor in the biosynthesis of phytosiderophores. Arabidopsis lines accumulating 4- and 100-fold more NA thanwild-type plants were used in order to evaluate the impact of such an NA overaccumulation on iron homeostasis.The expression of iron-regulated genes including the IRT1/FRO2 iron uptake system is highly induced at thetranscript level under both iron-sufficient and iron-deficient conditions. Nevertheless, NA...

Iron dynamics in the rhizosphere : consequences for plant health and nutrition Inra
Robin, A.; Vansuyt, G.; Hinsinger, P.; Meyer, J.M.; Briat, J.F.; Lemanceau, P..
Iron is an essential micronutrient for most organisms due to its role in fundamental metabolic processes. In cultivated soils, soil solution iron is mostly oxidized [Fe(III) species] unless local anoxic conditions develop. The concentration of these Fe(III) species is small in soil solution due to the low solubility of ferric oxides, oxyhydroxides, and hydroxides, which is minimal at neutral and alkaline pH. In the rhizosphere, iron concentration in the soil solution is even lower because of its uptake by aerobic organisms (plants and microorganisms), leading to a high level of competition for Fe(III). In order to face iron competition, these organisms have evolved active uptake strategies based on acidification, chelation, and/or reduction processes. Iron...

Iron utilization and metabolism in plants Inra
Briat, J.F.; Curie, C.; Gaymard, F..
The solubilization and long-distance allocation of iron between organs and tissues, as well as its subcellular compartmentalization and remobilization, involve various chelation and oxidation/reduction steps, transport activities and association with soluble proteins that store and buffer this metal. Maintaining iron homeostasis is an important determinant in building prosthetic groups such as heme and Fe-S clusters, and in assembling them into apoproteins, which are major components of plant metabolism. Such processes require complex protein machineries located in mitochondria and plastids. An essential role for iron metabolism and utilization in plant productivity is evidenced by the strong iron requirement for proper photosynthetic reactions.

Knock-out of ferritin AtFer1 causes earlier onset of age-dependent leaf senescence in Arabidopsis Inra
Murgia, I.; Vazzola, V.; Tarantino, D.; Cellier, F.; Ravet, K.; Briat, J.F.; Soave, C..
Ferritins are iron-storage proteins involved in the regulation of free iron levels in the cells. Arabidopsis thaliana AtFer1 ferritin, one of thebest characterized plant ferritin isoforms to date, strongly accumulates upon treatment with excess iron, via a nitric oxide-mediated pathway.However other environmental factors, such as exposure to oxidative stress or to pathogen attack, as well as developmental factors regulate AtFer1 transcript levels. In particular, recent findings have highlighted an accumulation of the ferritin transcript during senescence. To investigatethe physiological relevance of AtFer1 ferritin during senescence we isolated an Arabidopsis mutant knock-out in the AtFer1 gene, which wenamed atfer1-2. We analyzed it together with a...

Mitochondrial localization of Arabidopsis thaliana Isu Fe-S scaffold proteins Inra
Léon, S.; Touraine, B.; Briat, J.F.; Lobréaux, S..
Isu are sca.old proteins involved in iron-sulfur cluster biogenesis and playing a key role in yeast mitochondria and Escherichia coli. In this work, we have characterized the Arabidopsis thaliana Isu gene family. AtIsu1,2,3 genes encode polypeptides closely related to their bacterial and eukaryotic counterparts. AtIsu expression in a Saccharomyces cerevisiae ?isu1 ?nfu1 hermosensitive mutant led to the growth restoration of this strain at 37 0C. Using Isu-GFP fusions expressed in leaf protoplasts and immunodetection in organelle extracts, we have shown that Arabidopsis Isu proteins are located only into mitochondria, supporting the existence of an Isu-independent Fe-S assembly machinery in plant plastids.

Post-translational regulation of AtFER2 ferritin in response to intracellular iron trafficking during fruit development in Arabidopsis Inra
Ravet, K.; Touraine, B.; Kim, S.A.; Cellier, F.; Thomine, S.; Guerinot, M.L.; Briat, J.F.; Gaymard, F..
Ferritins are major players in plant iron homeostasis. Surprisingly, their overexpression in transgenic plants led only to a moderate increase in seed iron content, suggesting the existence of control checkpoints for iron loading and storage in seeds. This work reports the identification of two of these checkpoints. First, measurement of seed metal content during fruit development in Arabidopsis thaliana reveals a similar dynamic of loading for Fe, Mn, Cu, and Zn. The step controlling metal loading into the seed occurs by the regulation of transport from the hull to the seed. Second, metal loading and ferritin abundance were monitored in different genetic backgrounds affected in vacuolar iron transport (AtVIT1, AtNRAMP3, AtNRAMP4) or plastid iron storage...

Regulation of iron homeostasis in Arabidopsis thaliana by the clock regulator time for coffee Inra
Duc, C.; Cellier, F.; Lobreaux, S.; Briat, J.F.; Gaymard, F..
In plants, iron homeostasis is tightly regulated to supply sufficient amounts of this metal for an optimal growth while preventing excess accumulation to avoid oxidative stress. To identify new regulators of iron homeostasis, a luciferase-based genetic screen using the Arabidopsis AtFer1 ferritin promoter as a target was developed. This screen identified TIME FOR COFFEE(TIC) as a regulator of AtFer1 gene expression. TIC was previously described as a nuclear regulator of the circadian clock. Mutants in the TIC gene exhibited a chlorotic phenotyperescued by exogenous iron addition and are hypersensitive to iron during the early stages of development. We showed that iron overload-responsive genes are regulated by TIC and by the central oscillator of the...

Root-to-shoot long-distance circulation of nicotianamine and nicotianamine-nickel chelates in the metal hyperaccumulator Thlaspi caerulescens Inra
Mari, S.; Gendre, D.; Pianelli, K.; Ouerdane, L.; Lobinski, R.; Briat, J.F.; Lebrun, M.; Czernic, P..
Plant metal hyperaccumulator species are widely used as models to unravel the heavy metal tolerance and hyperaccumulation mechanisms. Thlaspi caerulescens is capable of tolerating and hyperaccumulating Zn, Cd, and Ni. A search for factors involved in the cellular tolerance to Ni, based on yeast screens, led to isolation of a cDNA encoding a functional nicotianamine (NA) synthase (NAS). The T. caerulescens genome appears to contain a single copy of the NAS gene named TcNAS whose expression is restricted to the leaves. The analysis of dose-response and time-course Ni treatments have revealed that the exposure to Ni triggers the accumulation of NA in the roots. Because neither TcNAS expression nor NAS activity were detected in the roots, the NA accumulation...

TcYSL3, a member of the YSL gene family from the hyper-accumulator Thlaspi Inra
Gendre, D.; Czernic, P.; CONEJERO, G.; Pianelli, K.; Briat, J.F.; Lebrun, M.; MARI, S..
The two main features of plant hyper-accumulator species are the massivetranslocation of heavy metal ions to the aerial parts and their tolerance to such highmetal concentrations. Recently, several lines of evidence have indicated a role for nicotianamine (NA) in metal homeostasis, through the chelation and transport of NA-metal complexes. The function of transport of NA-metal chelates, required for theloading and unloading of vessels, has been assigned to the Yellow Stripe 1 (YSL)-Likefamily of proteins. We have characterized three YSL genes in Thlaspi caerulescens inthe context of hyper-accumulation. The three YSL genes are expressed at high ratescompared with their Arabidopsis thaliana homologs but with distinct patterns. WhileTcYSL7 was highly...

The iron-responsive element (IRE)/iron-regulatory protein 1 (IRP1)-cytosolic aconitase iron-regulatory switch does not operate in plants. Inra
Arnaud, N.; Ravet, K.; Borlotti, A.; Touraine, B.; Boucherez, J.; Fizames, C.; Briat, J.F.; Cellier, F.; Gaymard, F..
Animal cytosolic ACO (aconitase) and bacteria ACO are able to switch to RNA-binding proteins [IRPs (iron-regulatory proteins)],thereby playing a key role in the regulation of iron homoeostasis. In the model plant Arabidopsis thaliana, we have identified three IRP1 homologues, named ACO1-3. To determine whether or not they may encode functional IRP proteins and regulate iron homoeostasis in plants, we have isolated loss-of-function mutants in the three genes. The aco1-1 and aco3-1 mutants show a clear decrease in cytosolic ACO activity. However, none of the mutants is affected in respect of the accumulation of the ferritin transcript or protein in response to iron excess. cis-acting elements potentially able to bind to the IRP have been searched for in...

The NRAMP6 metal transporter contributes to cadmium toxicity Inra
Caillatte, R.; Lapeyre, B.; Briat, J.F.; Mari, S.; Curie, C..
NRAMP (natural resistance-associated macrophage protein) homologues are evolutionarily conserved bivalent metal transporters. In Arabidopsis, AtNRAMP3 and AtNRAMP4 play a key role in iron nutrition of the germinating plantlet by remobilizing vacuolar iron stores. In the present paper we describe the molecular and physiological characterization of AtNRAMP6. AtNRAMP6 is predominantly expressed in the dry seed embryo and to a lesser extent in aerial parts. Its promoter activity is found diffusely distributed in cotyledons and hypocotyl, as well as in the vascular tissue region of leaf and flower. We show that the AtNRAMP6 transcript coexists with a partially spliced isoform in all shoot cell types tested. When expressed in yeast, AtNRAMP6, but not its...
