Abstract
We need to improve food production to feed the ever growing world population especially in a changing climate. Nutrient deficiency in soils is one of the primary bottlenecks affecting the crop production both in developed and developing countries. Farmers are forced to apply synthetic fertilizers to improve the crop production to meet the demand. Understanding the mechanism of nutrient transport is helpful to improve the nutrient-use efficiency of crops and promote the sustainable agriculture. Many transporters involved in the acquisition, export and redistribution of nutrients in plants are characterized. In these studies, heterologous systems like yeast and Xenopus were most frequently used to study the transport function of plant nutrient transporters. CRIPSR/Cas system introduced recently has taken central stage for efficient genome editing in diverse organisms including plants. In this review, we discuss the key nutrient transporters involved in the acquisition and redistribution of nutrients from soil. We draw insights on the possible application CRISPR/Cas system for improving the nutrient transport in plants by engineering key residues of nutrient transporters, transcriptional regulation of nutrient transport signals, engineering motifs in promoters and transcription factors. CRISPR-based engineering of plant nutrient transport not only helps to study the process in native plants with conserved regulatory system but also aid to develop non-transgenic crops with better nutrient use-efficiency. This will reduce the application of synthetic fertilizers and promote the sustainable agriculture strengthening the food and nutrient security.

Abstract
Salinity is among the most important abiotic stresses affecting crop production throughout the earth. Halophyte plants can sustain high salinity levels, therefore elucidating molecular mechanisms underlying their salinity resistance is beneficial for crop improvement. Aeluropus littoralis, a halophyte weed, is a great genetic resource for this purpose. Isolated expressed sequence taq (EST) sequences from A. littoralis under salinity stress, have given us the chance to find and analyze transcripts of genes involved in response to salinity. Transcriptome analyses indicated the expression levels of mRNAs corresponding to 10 of sequences were increased under treatments. All mRNAs were significantly induced under salt treatment with the highest peaks observed at different hours of treatments. Moreover, the full-length cDNA of vacuolar H+-pyrophosphatase (VP) was isolated utilizing 3' and 5' rapid amplification of cDNA ends polymerase chain reaction (RACE-PCR) and characterized (GenBank accession number of KT253223.1). The extracted full-length of VP was 2732 bp, which contained ORF of 2292 bp encoding 763 amino acids.

Abstract
High-affinity K+ (HAK) transporters are encoded by a large family of genes and are ubiquitous in the plant kingdom. These HAK-type transporters participate in low- and high-affinity potassium (K+) uptake and are crucial for the maintenance of K+ homeostasis under hostile conditions. In this study, the full-length cDNA of CcHAK1 gene was isolated from roots of the habanero pepper (Capsicum chinense). CcHAK1 expression was positively regulated by K+ starvation in roots and was not inhibited in the presence of NaCl. Phylogenetic analysis placed the CcHAK1 transporter in group I of the HAK K+ transporters, showing that it is closely related to Capsicum annuum CaHAK1 and Solanum lycopersicum LeHAK5. Characterization of the protein in a yeast mutant deficient in high-affinity K+ uptake (WΔ3) suggested that CcHAK1 function is associated with high-affinity K+ uptake, with Km and Vmax for Rb of 50 μM and 0.52 nmol mg-1 min-1, respectively. K+ uptake in yeast expressing the CcHAK1 transporter was inhibited by millimolar concentrations of the cations ammonium ([Formula: see text]) and cesium (Cs+) but not by sodium (Na+). The results presented in this study suggest that the CcHAK1 transporter may contribute to the maintenance of K+ homeostasis in root cells in C. chinense plants undergoing K+-deficiency and salt stress.

Rice potassium transporter OsHAK1 is essential for maintaining potassium-mediated growth and functions in salt tolerance over low and high potassium concentration ranges. PLANT, CELL & ENVIRONMENT 2015; 38:2747-65. [PMID: 26046301 DOI: 10.1111/pce.12585] [Citation(s) in RCA: 146] [Impact Index Per Article: 16.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/01/2015] [Revised: 05/16/2015] [Accepted: 06/01/2015] [Indexed: 05/17/2023]
Abstract
Potassium (K) absorption and translocation in plants rely upon multiple K transporters for adapting varied K supply and saline conditions. Here, we report the expression patterns and physiological roles of OsHAK1, a member belonging to the KT/KUP/HAK gene family in rice (Oryza sativa L.). The expression of OsHAK1 is up-regulated by K deficiency or salt stress in various tissues, particularly in the root and shoot apical meristem, the epidermises and steles of root, and vascular bundles of shoot. Both oshak1 knockout mutants in comparison to their respective Dongjin or Manan wild types showed a dramatic reduction in K concentration and stunted root and shoot growth. Knockout of OsHAK1 reduced the K absorption rate of unit root surface area by ∼50-55 and ∼30%, and total K uptake by ∼80 and ∼65% at 0.05-0.1 and 1 mm K supply level, respectively. The root net high-affinity K uptake of oshak1 mutants was sensitive to salt stress but not to ammonium supply. Overexpression of OsHAK1 in rice increased K uptake and K/Na ratio. The positive relationship between K concentration and shoot biomass in the mutants suggests that OsHAK1 plays an essential role in K-mediated rice growth and salt tolerance over low and high K concentration ranges.

Abstract
Salinity adversely affects plant growth and development, and disturbs intracellular ion homeostasis, resulting in cellular toxicity. Plants that tolerate salinity, halophytes, do so by manifesting numerous physiological and biochemical processes in coordination to alleviate cellular ionic imbalance. The present study was undertaken to analyse the salt tolerance mechanism in Aeluropus lagopoides (L.) trin. Ex Thw. (Poaceae) at both physiological and molecular levels. Plants secreted salt from glands, which eventually produced pristine salt crystals on leaves and leaf sheaths. The rate of salt secretion increased with increasing salt concentration in the growth medium. Osmotic adjustment was mainly achieved by inorganic osmolytes (Na(+)) and at 100 mM NaCl no change was observed in organic osmolytes in comparison to control plants. At 300 mM NaCl and with 150 mM NaCl + 150 mM KCl, the concentration of proline, soluble sugars and amino acids was significantly increased. Transcript profiling of transporter genes revealed differential spatial and temporal expressions in both shoot and root tissues in a manner synchronized towards maintaining ion homeostasis. In shoots, AlHKT2;1 transcript up-regulation was observed at 12 and 24 h in all the treatments, whereas in roots, maximum induction was observed at 48 h with K(+) starvation. The HAK transcript was relatively abundant in shoot tissue with all the treatments. The plasma membrane Na(+)/H(+) antiporter, SOS1, and tonoplast Na(+)/H(+) antiporter, NHX1, were found to be significantly up-regulated in shoot tissue. Our data demonstrate that AlHKT2;1, HAK, SOS1, NHX1 and V-ATPase genes play a pivotal role in regulating the ion homeostasis in A. lagopoides.

Abstract
Cloning and characterizations of plant K(+) transport systems aside from Arabidopsis have been increasing over the past decade, favored by the availability of more and more plant genome sequences. Information now available enables the comparison of some of these systems between species. In this review, we focus on three families of plant K(+) transport systems that are active at the plasma membrane: the Shaker K(+) channel family, comprised of voltage-gated channels that dominate the plasma membrane conductance to K(+) in most environmental conditions, and two families of transporters, the HAK/KUP/KT K(+) transporter family, which includes some high-affinity transporters, and the HKT K(+) and/or Na(+) transporter family, in which K(+)-permeable members seem to be present in monocots only. The three families are briefly described, giving insights into the structure of their members and on functional properties and their roles in Arabidopsis or rice. The structure of the three families is then compared between plant species through phylogenic analyses. Within clusters of ortologues/paralogues, similarities and differences in terms of expression pattern, functional properties and, when known, regulatory interacting partners, are highlighted. The question of the physiological significance of highlighted differences is also addressed.

Abstract
The AlHAK1 gene encoding a high-affinity K+ transporter was isolated from Aeluropus littoralis (Gouan) Parl, a graminaceous halophyte, and plays a crucial role in nutrition and ion homeostasis in plant cell. To investigate the regulation role of AlHAK1 on the transcriptional level, an about 1.3 kb 5'-flanking region of the AlHAK1 gene containing a putative promoter was cloned by genome walking method. Cis-regulatory elements analysis showed AlHAK1-promoter region contained typical TATA and CAAT boxes, and some growth and development relative motifs, as well as environmental re-sponsive elements. To reveal the function and regulating role, the AlHAK1 promoter was fused to the β-glucuronidase (GUS) reporter gene in the pCAMBIA1301 vector and introduced into rice via Agrobacterium-mediated transformation. Histo-chemical staining indicated that the GUS expression directed by AlHAK1 promoter was observed in leaves, stems, roots, anther, lemma, and palea. GUS quantitative fluorometric analysis indicated that GUS activity directed by AlHAK1 promoter was lower than CaMV35S and Ubiquitin constitutive promoters; however, in the roots and stems the GUS activity was rela-tively high and displayed a tissue-specific expression pattern. Under ABA, high temperature or drought stress, the GUS activity directed by AlHAK1 promoter was inducible in the roots and stems, suggesting the elements of HSE (-682 bp) and MybBS (-1 268 bp) might play a role in the inducible regulation.
