The uptake of ammonium, nitrate, phosphorus, and potassium ions by roots is mediated specific ion transporter or channel proteins, protein phosphorylation regulation events occurring on these proteins their regulators determine ultimate activity. Elucidating the mechanism which modification regulates nutrient will advance plant breeding for high nutrient-use efficiency. In this review, it concluded that root absorption system composed several, but not all, members a family. Under nutrient-starvation conditions, phosphorylation-based associated transcription factors increases transporter- channel-mediated capacity via direct function activity enhancement, allowing more trafficking to plasma membrane, strengthening interaction transporters channels with partner increasing stability, transcriptional activation. excessive suppresses reversing processes.

Excessive iron deposition in root apoplast is involved in growth arrest of roots in response to low pH

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.

The transcription factors, STOP1 and TCP20, are required for root system architecture alterations in response to nitrate deficiency

Proceedings of the National Academy of Sciences, Год журнала: 2023, Номер 120(35)

Nitrate distribution in soils is often heterogeneous. Plants have adapted to this by modifying their root system architecture (RSA). Previous studies showed that NITRATE-TRANSPORTER1.1 (NRT1.1), which also transports auxin, helps inhibit lateral primordia (LRP) emergence nitrate-poor patches, preferentially transporting auxin away from the LRP. In study, we identified regulatory for response involving transcription factor (TF), SENSITIVE-TO-PROTON-RHIZOTOXICITY1 (STOP1), accumulated nuclei of LRP cells under nitrate deficiency and directly regulates Arabidopsis NRT1.1 expression. Mutations STOP1 mimic phenotype loss-of-function mutant deficiency, compared wild-type plants, including increased LR growth higher DR5promoter activity (i.e., signaling/activity). deficiency–induced inhibition was almost completely reversed when TF, TEOSINTE-BRANCHED1,-CYCLOIDEA,-PCF-DOMAIN-FAMILY-PROTEIN20 (TCP20), a known activator expression, were both mutated. Thus, STOP1-TCP20 required activation expression leading reduced regions. We found STOP1-mediated more active as media becomes acidic, correlates with reductions soil pH acidic. has been shown be involved RSA modifications phosphate potassium uptake, hence, our findings indicate regulation low availability major fertilizer nutrients, nitrogen, phosphorus potassium, all involve STOP1, may allow plants maintain appropriate complex varying nutrients.

Jasmonate signaling modulates root growth by suppressing iron accumulation during ammonium stress

PLANT PHYSIOLOGY, Год журнала: 2024, Номер unknown

Abstract Plants adapt to changing environmental conditions by adjusting their growth physiology. Nitrate (NO3−) and ammonium (NH4+) are the major inorganic nitrogen forms for plant uptake. However, high NH4+ inhibits growth, roots undergo striking changes, such as inhibition of cell expansion division, leading reduced root elongation. In this work, we show that modulates metabolism developmental physiology inhibiting iron (Fe)-dependent Jasmonate (JA) signaling response in Arabidopsis (Arabidopsis thaliana). Transcriptomic data suggested availability regulates Fe JA-responsive genes. High levels led enhanced accumulation, which impaired balance suppressing JA biosynthesis response. Integrating pharmacological, physiological, genetic experiments revealed involvement Fe-derived responses regulating through modulation pathway during stress. The transcription factor MYC2 directly bound promoter NITRATE TRANSPORTER 1.1 (NRT1.1) repressed it optimize NH4+/Fe-JA adaptation Our findings illustrate intricate between nutrient hormone-derived pathways appear essential optimizing physiological metabolic NH4+/Fe

Cytosolic pH homeostasis is a precondition for the normal growth and stress responses in plants, H+ flux across plasma membrane essential cytoplasmic control. Hence, this review focuses on seven types of proteins that possess direct transport activity, namely, H+-ATPase, NHX, CHX, AMT, NRT, PHT, KT/HAK/KUP, to summarize their plasma-membrane-located family members, effect corresponding gene knockout and/or overexpression cytosolic pH, pathway, functional regulation by extracellular/cytosolic pH. In general, H+-ATPases mediate extrusion, whereas most members other six influx, thus contributing directly modulating membrane. The fact some AMTs/NRTs H+-coupled substrate intra-family facilitate H+-uncoupled transport, demonstrates not all transporters mechanisms, using mechanism protein represent case entire suitable. activity these regulated extracellular with different structural bases transfer among proteins. Notably, distinct regulatory characterization underlying residues transfer. This anticipated understanding molecular basis homeostasis. Despite progress, strategy cooperation needs further investigation.

Emerging trends in nitrogen and phosphorus signalling in photosynthetic eukaryotes

Phosphorus (P) and nitrogen (N) are the major nutrients that constrain plant algal growth in nature. Recent advances understanding nutrient signalling mechanisms of these organisms have revealed molecular attributes to optimise N P acquisition. This has illuminated importance interplay between regulatory networks, highlighting a need study synergistic interactions rather than single-nutrient effects. Emerging insights polyphyletic model plants algae hint that, although core P-starvation components conserved, distinct for (and N) sensing arisen. Here, diverse photosynthetic eukaryotes examined, drawing parallels differences taxa. Future directions understand their basis, evolution, ecology proposed.
