Nitrogen (N) is an essential mineral element for plants and the main component of protein, nucleic acid, phospholipid, chlorophyll, hormones, vitamins alkaloids. It involved in all stages plant growth development. Low-N stress seriously hinders reduces yield quality. Plants have evolved a series elaborate regulatory mechanisms N uptake assimilation to cope with different soil states. After absorbed utilized by plants, it plays important roles phytohormones, microRNA (miRNA), root development mycorrhizal symbiosis environmental stress. Here, we highlight research progress on regulation absorption assimilation. Then, emphasize regarding hormone signals, miRNA, lateral growth, drought resistance, anthocyanin synthesis symbiosis. A thorough understanding uptake, utilization interaction other biological processes helpful improve use efficiency breed “less-input-more-output”.

Abstract Anthocyanins play critical roles in protecting plant tissues against diverse stresses. The complicated regulatory networks induced by various environmental factors modulate the homeostatic level of anthocyanins. Here, we show that anthocyanin accumulation is brassinosteroids (BRs) Arabidopsis (Arabidopsis thaliana) shoots and shed light on underlying mechanism. We observed levels are altered considerably BR-related mutants, BRs induce upregulating expression biosynthetic genes. Our genetic analysis indicated BRASSINAZOLE RESISTANT 1 (BZR1) PRODUCTION OF ANTHOCYANIN PIGMENT (PAP1) essential for BR-induced accumulation. BR-responsive transcription factor BZR1 directly binds to PAP1 promoter, regulating its expression. In addition, found intense caused pap1-D-dominant mutation significantly reduced BR implying activity required function after transcription. Moreover, demonstrated physically interacts with cooperatively regulate PAP1-target genes, such as TRANSPARENT TESTA 8, DIHYDROFLAVONOL 4-REDUCTASE, LEUKOANTHOCYANIDIN DIOXYGENASE. findings indicate functions an integral component PAP1-containing complex, contributing increased biosynthesis. Notably, also functional interaction low nitrogen stress. Taken together, our results demonstrate BR-regulated promotes biosynthesis through cooperative MBW complex.

Phosphorylation regulation of nitrogen, phosphorus, and potassium uptake systems in plants

The Crop Journal, Год журнала: 2023, Номер 11(4), С. 1034 - 1047

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. Strengthening items increase weakening are conducive show potential as strategies use

Recent Advances in the Crosstalk between Brassinosteroids and Environmental Stimuli

Plant and Cell Physiology, Год журнала: 2024, Номер 65(10), С. 1552 - 1567

Опубликована: Март 13, 2024

Due to their sessile lifestyle, plants need optimize growth in order adapt ever-changing environments. Plants receive stimuli from the environment and convert them into cellular responses. Brassinosteroids (BRs), as growth-promoting steroid hormones, play a significant role tradeoff between environmental Here, we provide comprehensive summary for understanding crosstalk BR various stresses, including water availability, temperature fluctuations, salinization, nutrient deficiencies diseases. We also highlight bottlenecks that be addressed future studies. Ultimately, suppose improve plant adaptability crop yield by excavating natural mutants or modifying signaling its targets.

Integrated transcriptomics and metabolomics analyses provide new insights into cassava in response to nitrogen deficiency

Frontiers in Plant Science, Год журнала: 2025, Номер 15

Опубликована: Янв. 14, 2025

Nitrogen deficiency is a key constraint on crop yield. Cassava, the world's sixth-largest food and crucial source of feed industrial materials, can thrive in marginal soils, yet its yield still significantly affected by limited nitrogen availability. Investigating cassava's response mechanisms to scarcity therefore essential for advancing molecular breeding identifying nitrogen-efficient varieties. This research undertook comprehensive analysis cassava seedlings' physiological, gene expression, metabolite responses under low stress. Findings revealed that drastically suppressed seedling growth, reduced nitrate ammonium transport aerial parts, led marked increase carbohydrate, reactive oxygen species, ion levels leaves. Transcriptomic metabolomic analyses further demonstrated notable alterations genes metabolites linked carbon metabolism, flavonoid biosynthesis, purine metabolic pathway. Additionally, several transcription factors associated with biosynthesis nitrogen-deficient conditions were identified. Overall, this study offers fresh insights valuable genetic resources unraveling adaptive deprivation.
