Fertilizer Use Efficiency (FUE) is a measure of the potential an applied fertilizer to increase its impact on uptake and utilization nitrogen (N) present in soil/plant system. The productivity N depends supply those nutrients well-defined stage yield formation that are decisive for utilization. Traditionally, plant nutritional status evaluated by using chemical methods. However, nowadays, correct doses, absorption reflection solar radiation used. Fertilization efficiency can be increased not only adjusting dose plant’s requirements, but also removing all soil factors constrain nutrient their transport from root surface. Among them, compaction pH relatively easy correct. goal new formulas fertilizers availability synchronization release with demand. aim non-nitrogenous control effectiveness A wide range actions required reduce amount which pollute ecosystems adjacent fields.

Опубликована: Июль 8, 2023

Abstract Every living organism on Earth depends its interactions with other organisms. In the rhizosphere, plants and microorganisms constantly exchange signals influence each other’s behavior. Recent studies have shown that many beneficial rhizosphere microbes can produce specific signaling molecules affect plant root architecture therefore could substantial effects above-ground growth. This review examines these chemical summarizes their mechanisms of action, aim enhancing our understanding plant–microbe providing references for comprehensive development utilization active components in agricultural production. addition, we highlight future research directions challenges, such as searching microbial to induce primary development.

Insights on Phytohormonal Crosstalk in Plant Response to Nitrogen Stress: A Focus on Plant Root Growth and Development

International Journal of Molecular Sciences, Год журнала: 2023, Номер 24(4), С. 3631 - 3631

Nitrogen (N) is a vital mineral component that can restrict the growth and development of plants if supplied inappropriately. In order to benefit their development, have complex physiological structural responses changes in nitrogen supply. As higher multiple organs with varying functions nutritional requirements, they coordinate at whole-plant level based on local long-distance signaling pathways. It has been suggested phytohormones are substances such The pathway closely associated as auxin (AUX), abscisic acid (ABA), cytokinins (CKs), ethylene (ETH), brassinosteroid (BR), strigolactones (SLs), jasmonic (JA), salicylic (SA). Recent research shed light how interact modulate physiology morphology. This review provides summary phytohormone affects root system architecture (RSA) response availability. Overall, this contributes identifying recent developments interaction between N, well serving foundation for further study.

Nitrogen sensing and regulatory networks: it's about time and space

The Plant Cell, Год журнала: 2024, Номер 36(5), С. 1482 - 1503

Опубликована: Фев. 14, 2024

A plant's response to external and internal nitrogen signals/status relies on sensing signaling mechanisms that operate across spatial temporal dimensions. From a comprehensive systems biology perspective, this involves integrating responses in different cell types over long distances ensure organ coordination real time yield practical applications. In prospective review, we focus novel aspects of (N) sensing/signaling uncovered using approaches, largely the model Arabidopsis. The span: transcriptional N-dose mediated by Michaelis-Menten kinetics, role master NLP7 transcription factor as nitrate sensor, its nitrate-dependent TF nuclear retention, "hit-and-run" mode target gene regulation, cascade identified "network walking." Spatial N-sensing/signaling have been type-specific studies roots root-to-shoot communication. We explore new approaches single-cell sequencing data, trajectory inference, pseudotime analysis well machine learning artificial intelligence approaches. Finally, unveiling underlying dynamics networks species from crop could pave way for translational improve nitrogen-use efficiency crops. Such outcomes potentially reduce detrimental effects excessive fertilizer usage groundwater pollution greenhouse gas emissions.

Soil Fertility Clock—Crop Rotation as a Paradigm in Nitrogen Fertilizer Productivity Control

Plants, Год журнала: 2022, Номер 11(21), С. 2841 - 2841

The Soil Fertility Clock (SFC) concept is based on the assumption that critical content (range) of essential nutrients in soil adapted to requirements most sensitive plant cropping sequence (CS). This provides a key way effectively control productivity fertilizer nitrogen (Nf). production goals farm are set for maximum crop yield, which defined by environmental conditions process. target can be achieved, provided efficiency Nf approaches 1.0. Nitrogen (in fact, nitrate) determining yield-forming factor, but only when it balanced with supply other (nitrogen-supporting nutrients; N-SNs). condition achieving this level effectiveness factors, including N-SNs, should at ≤1.0. A source N-SNs zone occupied roots. applied order restore their topsoil required given CS. Other plants CS provide timeframe active controlling distance from range.

Effects of Drought Stress on Leaf Functional Traits and Biomass Characteristics of Atriplex canescens

Plants, Год журнала: 2024, Номер 13(14), С. 2006 - 2006

Опубликована: Июль 22, 2024

Drought is a critical factor constraining plant growth in arid regions. However, the performance and adaptive mechanism of Atriplex canescens (A. canescens) under drought stress remain unclear. Hence, three-year experiment with three gradients was performed common garden, leaf functional traits, biomass partitioning patterns A. were investigated. The results showed that had significant effects on traits. maintained content malondialdehyde (MDA) activity superoxide dismutase (SOD), but peroxidase (POD) catalase (CAT) decreased, proline (Pro) soluble sugar (SS) increased only heavy stress. Under stress, leaves became smaller denser, specific area (SLA) dry matter (LDMC) stability. Total decreased 60% to 1758 g seed 10% 20% non-stress group, there no difference root biomass.

MDA significantly negatively correlated biomass, while SPAD positively total aboveground organs POD, CAT, Pro SS correlations ratio. morphological traits related shape weight allocation. Our study demonstrated made tradeoffs between potential tolerance evolved conservative strategy.

Interaction of BES1 and LBD37 transcription factors modulates brassinosteroid-regulated root forging response under low nitrogen in arabidopsis

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

Brassinosteriod (BR) plays important roles in regulation of plant growth, development and environmental responses. BR signaling regulates multiple biological processes through controlling the activity BES1/BZR1 regulators. Apart from promotion is also involved root foraging response under low nitrogen, however how regulate this process remains unclear. Here we show that BES1 LBD37 antagonistically nitrogen conditions. Both transcriptional level dephosphorylated BES1, significant induced by predominantly root. Phenotypic analysis showed gain-of-function mutant or overexpression transgenic plants exhibits progressive outgrowth lateral to negatively repressors nitrate pathway positively several key genes required for NO3- uptake signaling. In contrast, knock-down BES1-RNAi exhibited a dramatical reduction elongation N. Furthermore, identified interacting protein, LBD37, which negative repressor N availability signals. Our results can inhibit repression on N-responsive genes. thus demonstrated BES1-LBD37 module acts critical nodes integrate modulate forging at LN condition.
