“…Ding et al (2020) demonstrated that SPDT transporter in Arabidopsis thaliana showed a high affinity for Pi transport, as it was able to uptake Pi when injected into the Xenopus oocyte. Furthermore, its localization has been shown in the plasma membrane, while Wang et al., 2021 reported its localization in the chloroplast. These data are in agreement with reported SPDT genes which confer grain lpa phenotype (Larson et al., 2000; Liu et al., 2007).…”

“…Despite of considerable progress in understanding inorganic phosphate (Pi) acquisition and the response to its starvation, no direct link is reported between these traits and grain P concentration (Baker et al., 2015; Lal et al., 2019). The mineral nutrients needed for growth and development is absorbed mainly in the root hair, which is further translocated to the different organ through the xylem (Wang et al., 2021). Recent research has shown that the transport of minerals to the grain is mediated by transporter localized at the upper nodes of the plants.…”

Phosphorus (P) flow in agricultural land depends on the P taken off from harvested product, its losses through runoff and fertilizer applied to balance the removed P. Phytic acid (PA), the major storage form of phosphorus (P) in cereal grains is a key anti‐nutrient for human and non‐ruminants leads to eutrophication of waterways. As the natural non‐renewable P reserves are limited, enhancing P use efficiency is needed for field crops. SULTR‐like phosphorus distribution transporter (SPDT) is a novel rice transporter transfer P to the grain. Any alteration in transporter gene reduce grain P with concomitant rise in the leaves. A low PA (3.0 g/kg) rice Khira was identified where a single nucleotide mutation in LOC_Os06g05160 gene encoding SPDT showed low P transportation to grain. An amino acid change was detected as Valine‐330 to Alanine at the 3′ end of fifth exon. Highest expression of SPDT was observed in node I of rice as compared to low PA genotype. The mutation in SPDT could significantly affect P and PA accumulation in the grains with increased mineral bioavailability. Practical applications Excessive P application in crop leads to higher production cost as well as rapid depletion of limited rock phosphate. Alteration of P transporter function in the rice lower PA and total P accumulation in the grains with increased mineral bioavailability. The re‐distributed P in the straw can be applied as manure to the rice field. Thus, less P will be removed from the field, result in the decreased requirement for P fertilizer.

“…The following RT-qPCR detection also confirmed this prediction, which indicated the regulatory role of light and dark in NtCIPK23 expression ( Figure 5c). As other CIPK23 genes are proved to occupy a crucial position in nutrition, development, and stress tolerance in plants [3,4,22,38], the upstream regulation pathway of NtCIPK23 might be an interesting point to be focused on.…”

CBL-interacting protein kinase (CIPK) family is a unique group of serine/threonine protein kinase family identified in plants. Among this family, AtCIPK23 and its homologs in some plants are taken as a notable group for their importance in ions transport and stress responses. However, there are limited reports on their roles in seedling growth and development, especially in Solanaceae plants. In this study, NtCIPK23, a homolog of AtCIPK23 was cloned from Nicotiana tabacum. Expression analysis showed that NtCIPK23 is mainly expressed in the radicle, hypocotyl, and cotyledons of young tobacco seedlings. The transcriptional level of NtCIPK23 changes rapidly and spatiotemporally during seed germination and early seedling growth. To study the biological function of NtCIPK23 at these stages, the overexpressing and CRISPR/Cas9-mediated knock-out (ntcipk23) tobacco lines were generated. Phenotype analysis indicated that knock-out of NtCIPK23 significantly delays seed germination and the appearance of green cotyledon of young tobacco seedling. Overexpression of NtCIPK23 promotes cotyledon expansion and hypocotyl elongation of young tobacco seedlings. The expression of NtCIPK23 in hypocotyl is strongly upregulated by darkness and inhibited under light, suggesting that a regulatory mechanism of light might underlie. Consistently, a more obvious difference in hypocotyl length among different tobacco materials was observed in the dark, compared to that under the light, indicating that the upregulation of NtCIPK23 contributes greatly to the hypocotyl elongation. Taken together, NtCIPK23 not only enhances tobacco seed germination, but also accelerate early seedling growth by promoting cotyledon greening rate, cotyledon expansion and hypocotyl elongation of young tobacco seedlings.

“…Inorganic Pi signaling and transport have been investigated extensively in model organisms such as A. thaliana and rice. PSR appears to involve both a long-distance, systemic response that senses cellular Pi levels, and a local, root tip inhibition response that senses extracellular Pi availability ( Wang et al, 2020d ). Sensing of cellular Pi levels relies on the PHR1-PHT1 module ( Puga et al, 2017 ; Lu et al, 2020 ), which is a multicomponent, transcriptional, and posttranscriptional regulatory network.…”

Nitrogen (N) and phosphorus (P) are the two predominant mineral elements, which are not only essential for plant growth and development in general but also play a key role in symbiotic N fixation in legumes. Legume plants have evolved complex signaling networks to respond to both external and internal levels of these macronutrients to optimize symbiotic N fixation in nodules. Inorganic phosphate (Pi) and nitrate (NO3−) are the two major forms of P and N elements utilized by plants, respectively. Pi starvation and NO3− application both reduce symbiotic N fixation via similar changes in the nodule gene expression and invoke local and long-distance, systemic responses, of which N-compound feedback regulation of rhizobial nitrogenase activity appears to operate under both conditions. Most of the N and P signaling and transport processes have been investigated in model organisms, such as Medicago truncatula, Lotus japonicus, Glycine max, Phaseolus vulgaris, Arabidopsis thaliana, Oryza sativa, etc. We attempted to discuss some of these processes wherever appropriate, to serve as references for a better understanding of the N and P signaling and transport during symbiosis.
