“…TaNRT2.1-6B encoded a dual-affinity nitrate transporter and was associated with N harvest index and grain yield. Overexpressing TaNRT2.1-6B increased grain yield and N uptake under low-and high-N conditions in a pot experiment [22]. Genotyping of a panel of 254 diverse wheat cultivars and landraces by the wheat 660k Axiom Array indicated that wheat breeding did not affect the polymorphisms of most of the NPF and NRT2 genes [18].…”

The increasing global population and the negative effects of nitrogen (N) fertilizers on the environment challenge wheat breeding to maximize yield potential and grain protein concentration (GPC) in an economically and environmentally friendly manner. Understanding the molecular mechanisms for the response of yield components to N availability and assimilates allocation to grains provides the opportunity to increase wheat yield and GPC simultaneously. This review summarized quantitative trait loci/genes which can increase spikes and grain number by enhancing N uptake and assimilation at relative early growth stage, and 1000-grain weight and GPC by increasing post-anthesis N uptake and N allocation to grains.

“…For instance, the dual-affinity of NO 3 transporter like AtNRT1.1 (AtNPF6.3) and the low-affinity transporter-like AtNR1.2 (AtNPF4.6/CHL1) in Arabidopsis thaliana (Arabidopsis; Huang et al, 1999;Liu and Tsay, 2003) were reported to be influenced under high NO 3 conditions. Similarly, the dualaffinity behaviour of NO 3 transporter, MtNRT1.3 in Medicago truncatula (barrel medick; Morere-Le Paven et al, 2011), and the low-affinity NO 3 transporter ZmNPF7.9 (NRT1.5) in maize (Wei et al, 2021) and OsNPF8.9 (OsNRT1.1, Os3g13274, or AF140606), the OsNRT1.1 allele of OsNPF6.5 (OsNRT1.1B), OsNPF2.4 (OsNRT1.6), and a possible 6-transmembrane NO 3 transporter OsNRT1.1b (AK066920) in rice (Xia et al, 2015;Fan et al, 2016;Li et al, 2022a) all were shown to be implicated in the uptake of NO 3 -. + respectively.…”

“…For instance, NO 3 transporter-like NRT2.1, NRT2.2, NRT2.4, and NRT2.5 require a partner protein, NAR2.1 (Kiba et al, 2012;Lezhneva et al, 2014;Zou et al, 2020) in Arabidopsis to acclimatize under such conditions. In addition, other transporters such as CmNRT2.1 in Chrysanthemum indicum (Chrysanthemum; Gu et al, 2016), TaNRT2.1-6B in wheat (Li et al, 2022a), BnaZSNRT2s in Brassica napus (Canola; Du et al, 2022) and OsNRT2.1, OsNRT2.2, OsNRT2.4 and their partner protein OsNAR2.1 in rice (Naz et al, 2019;Souza et al, 2022) also function as NO 3 influx transporters (Figure 2). Among all NO 3 transporters, the dual affinity NO 3 transporter NRT1.1 (AtNPF6.3) serve as a multifunctional protein with a critical role in both NO 3 acquisition and sensing.…”

“…The high-affinity nitrate transporter gene (OsNRT2.1) has been widely used for the production and remodelling of transgenic rice with optimized NO 3 utilization, which is critical for maintaining crop yield under low N conditions (Katayama et al, 2009). Additionally, under both limited and sufficient N conditions, overexpression of TaNRT2.1-6B (dual-affinity NO 3 transporter) increased N influx, root growth, SPAD value, grain yield, and NUE in wheat, whereas gene silence lines had the inverse effects (Li et al, 2022a). Similarly, in Hordeum vulgare (barley), overexpression of the high affinity NO 3 transporter, OsNRT2.3b under the influence of ubiquitin promoter optimized yield, NUE, and regulation of nutrient uptake and homeostasis (Luo et al, 2020).…”

In the current changing environment, salt stress has become a major concern for plant growth and food production worldwide. Understanding the mechanisms of how plants function in saline environments is critical for initiating efforts to mitigate the detrimental effects of salt stress. Agricultural productivity is linked to nutrient availability, and it is expected that the judicious metabolism of mineral nutrients has a positive impact on alleviating salt-induced losses in crop plants. Nitrogen (N) is a macronutrient that contributes significantly to sustainable agriculture by maintaining productivity and plant growth in both optimal and stressful environments. Significant progress has been made in comprehending the fundamental physiological and molecular mechanisms associated with N-mediated plant responses to salt stress. This review provided an (a) overview of N-sensing, transportation, and assimilation in plants; (b) assess the salt stress-mediated regulation of N dynamics and nitrogen use- efficiency; (c) critically appraise the role of N in plants exposed to salt stress. Furthermore, the existing but less explored crosstalk between N and phytohormones has been discussed that may be utilized to gain a better understanding of plant adaptive responses to salt stress. In addition, the shade of a small beam of light on the manipulation of N dynamics through genetic engineering with an aim of developing salt-tolerant plants is also highlighted.

“…The modulation of nitrate uptake systems and the proliferation of lateral roots regulate nitrogen acquisition [ 33 , 34 , 35 , 36 ]. It is generally considered that transporters encoded by the NRT1 and NRT2 families have a low and high affinity for nitrate, respectively [ 37 , 38 , 39 , 40 , 41 ]. Numerous signals regulate the expression of NRT genes.…”

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