Immense chemical diversity is one of the hallmark features plants. This chemo-diversity mainly underpinned by a highly complex and biodiverse biochemical machinery. Plant metabolic enzymes originated were inherited from their eukaryotic prokaryotic ancestors further diversified unprecedentedly high rates gene duplication functionalization experienced in land Unlike microbes, which display frequent horizontal transfer events multiple inputs energy organic carbon, plants predominantly rely on carbon generated CO 2 have relatively few transfers during recent evolutionary history. As such, plant networks evolved stepwise manner using existing as starting point under various constraints. That said, until recently, evolution only handful traits had been extensively investigated metabolism has received fraction attention of, development, for example. Advances metabolomics next-generation sequencing have, however, recently led to deeper understanding how wide range primary specialized (secondary) pathways both consequence natural selection domestication crop improvement processes. article part theme issue ‘The metabolism’.

Integrative spatial transcriptomic analysis pinpoints the role of the ferroxidase, TaMCO3, in wheat root tip iron mobilization

The Plant Journal, Год журнала: 2025, Номер 122(2)

Опубликована: Апрель 1, 2025

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.

The ferroxidases are critical for Fe(II) oxidation in xylem to ensure a healthy Fe allocation in Arabidopsis thaliana

Frontiers in Plant Science, Год журнала: 2022, Номер 13

The long-distance transport of iron (Fe) in the xylem is critical for maintaining systemic Fe homeostasis plants. loading form Fe(II) into and translocation Fe(III)–citrate have been identified, but how oxidized to Fe(III) remains unknown. Here, we showed that cell wall-resided ferroxidases LPR1 LPR2 (LPRs) were both specifically expressed vascular tissues Arabidopsis thaliana , while disruption them increased sap caused excessive deposition vessel wall under Fe-sufficient conditions. As a result, large amount accumulated roots shoots, hindering plant growth. Moreover, low-Fe conditions, LPRs preferentially induced old leaves, loss vasculature older leaves impeded allocation younger leaves. Therefore, resulted severer chlorosis young Fe-deficient Taken together, oxidation by plays an important role allocation, ensuring healthy normal

Recent advances in unraveling the mystery of combined nutrient stress in plants

The Plant Journal, Год журнала: 2023, Номер 117(6), С. 1764 - 1780

Опубликована: Ноя. 3, 2023

SUMMARY Efficiently regulating growth to adapt varying resource availability is crucial for organisms, including plants. In particular, the acquisition of essential nutrients vital plant development, as a shortage just one nutrient can significantly decrease crop yield. However, plants constantly experience fluctuations in presence multiple mineral nutrients, leading combined stress conditions. Unfortunately, our understanding how perceive and respond these stresses remains limited. Unlocking this mystery could provide valuable insights help enhance nutrition strategies. This review focuses specifically on regulation phosphorous homeostasis plants, with primary emphasis recent studies that have shed light intricate interactions between other elements, such nitrogen, iron, zinc, well non‐essential elements like aluminum sodium. By summarizing consolidating findings, aims contribute better cope stress.

Phosphate starvation regulates cellulose synthesis to modify root growth

PLANT PHYSIOLOGY, Год журнала: 2023, Номер 194(2), С. 1204 - 1217

Опубликована: Окт. 12, 2023

In the model plant Arabidopsis (Arabidopsis thaliana), absence of essential macro-nutrient phosphate reduces primary root growth through decreased cell division and elongation, requiring alterations to polysaccharide-rich wall surrounding cells. Despite its importance, regulation synthesis in response low levels is not well understood. this study, we show that plants increase cellulose roots under limiting conditions, which leads changes thickness structure wall. These contribute reduced low-phosphate conditions. Furthermore, found synthase complex (CSC) activity at plasma membrane increases during deficiency. Moreover, CSC likely due phosphorylation status synthases Specifically, CELLULOSE SYNTHASE 1 (CESA1) S688 site decreases Phosphomimic versions CESA1 with an S688E mutation showed significantly induction length Protein modeling suggests could play a role stabilizing activating CSC. This mechanistic understanding conditions provides potential strategies for changing responses soil content.

Chemistry assigns phosphorus and its most oxidized form, inorganic phosphate, unique roles for propelling bioenergetics metabolism in all domains of life, possibly since very origin on prebiotic Earth. For plants, access to the vital mineral nutrient profoundly affects growth, development vigour, thus constraining net primary productivity natural ecosystems crop production modern agriculture. Unlike other major biogenic elements, low abundance uneven distribution phosphate Earth’s crust result from peculiarities cosmochemistry geochemistry. Here, we trace chemical evolution element, geochemical cycle acceleration during history until present (Anthropocene) as well rise terrestrial plants. We highlight biological processes mobilization acquisition, first evolved bacteria, refined fungi algae expanded into powerful phosphate-prospecting strategies land plant colonization.

Phosphorus acquisition, translocation, and redistribution in maize

Journal of genetics and genomics/Journal of Genetics and Genomics, Год журнала: 2024, Номер unknown

Опубликована: Окт. 1, 2024

Phosphorus (P) is an essential nutrient for crop growth, making it important maintaining food security as the global population continues to increase. Plants acquire P primarily via uptake of inorganic phosphate (Pi) in soil through their roots. Pi, which usually sequestered soils, not easily absorbed by plants and represses plant growth. have developed a series mechanisms cope with deficiency. Moreover, fertilizer applications are critical maximizing yield. Maize major cereal cultivated worldwide. Increasing its P-use efficiency optimizing maize production. Over past two decades, considerable progresses been achieved research aimed at adapting varieties changes environmental supply. Here, we present overview morphological, physiological, molecular involved acquisition, translocation, redistribution combine advances Arabidopsis rice, better elucidate progress nutrition. Additionally, summarize correlation between abiotic stress responses. Clarifying relevant improving absorption use can guide future on sustainable agriculture.
