Arabidopsis primary root growth response to phosphate (Pi) deficiency is mainly controlled by changes in apoplastic iron (Fe). Upon Pi deficiency, Fe deposition the apical meristem activates pathways leading arrest of maintenance and inhibition cell elongation. Here, we report that a member uncharacterized cytochrome b561 DOMON domain (CYBDOM) protein family, named CRR, promotes reduction an ascorbate-dependent manner controls deposition. Under low Pi, crr mutant shows enhanced associated with increased meristematic division. Conversely, CRR overexpression abolishes rendering insensitive Pi. The single hyp1 double mutant, harboring null allele another CYDOM tolerance high-Fe stress upon germination seedling growth. uptake translocation shoot results plants highly sensitive excess. Our identify ferric reductase implicated homeostasis developmental responses abiotic stress, reveal biological role for CYBDOM proteins plants.

Improving nitrogen-use efficiency is an important path toward enhancing crop yield and alleviating the environmental impacts of fertilizer use. Ammonium (NH4+) energetically preferred inorganic N source for plants. The interaction NH4+ with other nutrients a chief determinant ammonium-use (AUE) tipping point ammonium toxicity, but these interactions have remained ill-defined. Here, we report that iron (Fe) accumulation critical factor determining AUE identified substance can enhance by manipulating Fe availability. under nutrition induces efflux in root system, reducing both growth Arabidopsis (Arabidopsis thaliana). Low external availability low plant status substantially protein N-glycosylation through Vitamin C1-independent pathway, thereby to increase during vegetative stage elevated supply. We confirm validity iron-ammonium species lettuce (Lactuca sativa). further show dolomite act as effective substrate subdue expression Phosphate Root 2 acidification rhizosphere. Our findings present strategy improve reveal underlying molecular-physiological mechanism.

Abstract To mobilize sparingly available phosphorus (P) in the rhizosphere, many plant species secrete malate to release P sorbed onto (hydr)oxides of aluminum and iron (Fe). In presence Fe, can provoke Fe over-accumulation root apoplast, triggering a series events that inhibit growth. Here, we identified HYPERSENSITIVE TO LOW P1 (HYP1), CYBDOM protein constituted DOMON cytochrome b 561 domain, as critical maintain cell elongation meristem integrity under low P. We demonstrate HYP1 mediates ascorbate-dependent trans-plasma membrane electron transport reduce ferric cupric substrates Xenopus laevis oocytes planta . expression is up-regulated response deficiency proximal zone apical meristem. Disruption leads increased callose accumulation causes significant transcriptional changes roots. further activity overcomes malate-induced accumulation, thereby preventing Fe-dependent growth arrest Collectively, our results uncover an metalloreductase protect meristems P-deficient plants from availability provide insights into physiological function yet poorly characterized but ubiquitous proteins.

The rhizotoxicity of protons (H+) in acidic soils is a fundamental constraint that results serious yield losses. However, the mechanisms underlying H+-mediated inhibition root growth are poorly understood. In this study, we revealed H+-induced Arabidopsis depends considerably on excessive iron deposition apoplast. Reducing such aberrant by decreasing supply or disrupting ferroxidases LOW PHOSPHATE ROOT 1 (LPR) and LPR2 attenuates inhibitory effect H+ primary efficiently. Further analysis showed triggers burst highly reactive oxygen species, consequently impairing normal development. Our study uncovered valuable strategy for improving ability plants to tolerate toxicity manipulating availability.

Phosphorus (P) and iron (Fe) are two essential mineral nutrients in plant growth. It is widely observed that interactions of P Fe could influence their availability soils affect homeostasis plants, which has received significant attention recent years. This review presents a summary latest advances the activation insoluble Fe-P complexes by soil properties, microorganisms, plants. Furthermore, we elucidate physiological molecular mechanisms underlying how plants adapt to interactions. also discusses current limitations potential avenues for promoting sustainable agriculture through optimization utilization efficiency crops.

SUMMARY Roots play a critical role in the sensing and absorption of essential minerals from rhizosphere. Iron (Fe) deficiency, for example, triggers well‐known series physiological molecular responses within roots that facilitate uptake, which differs between monocots dicots. In monocots, little is known about occur specific root development zones response to iron deprivation, how these differences result overall nutrient uptake. Here, we conducted transcriptome analysis wheat tips under Fe deficiency (−Fe) performed comparative with previous datasets generated whole root. Gene ontology differentially expressed genes highlighted significance oxidoreductase activity metal/ion transport tip, are mobilization. Interestingly, wheat, an allohexaploid species consisting three different genomes (A, B, D) displayed varying gene expression levels arising contributed similar functions. Detailed function at tip revealed multiple m ulti c opper o xidase (MCO) proteins, such as Fe‐responsive TaMCO3, likely contribute ferroxidase activity. Further characterization TaMCO3 shows it complements yeast FET3 mutant rescues −Fe sensitivity phenotype Arabidopsis atmco3 mutants by enhancing vascular loading. Transgenic lines overexpressing exhibited increased accumulation improved tolerance augmenting Fe‐mobilizing genes. Our findings highlight spatially resolved responses, suggesting strategies reprogram cells stress tolerance.
