“…Furthermore, the intensified Na + absorption interferes the ionic balance and predominantly restrains K + uptake due to the similar ionic diameter of two ions and, hence, disrupts membrane-anchored carriers actions and prevents many enzymes to be metabolically active and dynamic (Apse and Blumwald 2002). Moreover, under NaCl salinity, Na + partially substitutes Ca 2+ in cell walls, interferes the cell function, and affects plant yield and productivity, causing ionic imbalances or deficiency of nutrients (Farhodi 2011;Guo et al 2017). Cell membrane damage under salinity stress and the subsequent malondialdehyde production followed by cell membrane lipid components breakdown are reliable biomarkers to assay the plant responses to salinity stress (Farhodi 2011).…”

Salinity is an obstacle for plant growth and the exploitation of means like cation foliar to soften the negative effects is of interest. The impacts of NaCl salinity (0, 75, 150, and 225 mM) and nano-Zn and Fe foliar applications (0 and 3 mg L −1) were examined on yield and physiological characteristics of Rosmarinus officinalis grown in an open soilless culture system. Salinity decreased root growth and above-ground plant growth (fresh and dry weight), chlorophyll a and total chlorophyll content, and zinc accumulation. Nano-Fe and Zn foliar application had positive influence on the above-ground plant growth. The results showed that Zn 2+ content was affected by the interaction between salinity and nano-Fe and Zn foliar application. The highest content of Zn 2+ was found at no saline Zn-sprayed plants. The content of Zn 2+ , hydrogen peroxide (H 2 O 2), malondialdehyde (MDA), and phenolics were affected by the independent effects of salinity or foliar application. Salinity increased the H 2 O 2 and MDA content but nano-zinc and iron spraying alleviated salinity impacts and both H 2 O 2 and MDA decreased. Nano-Fe and Zn foliar application increased total phenolics and total flavonoids content. Proline and chlorophyll a content, Na + , K + amounts, and K + /Na + ratio were affected by the salinity stress. Salinity decreased K + content and K + /Na + ratio but increased Na + and proline content with more pronounced effects at 225 mM NaCl. Overall, foliar application of both elements improved the growth and salt tolerance of rosemary and their application would be advisable to the cultivation practices.

“…Interestingly, this inhibition is overcome when plants are not provided a nitrate pretreatment (Glass and Siddiqi, 1985). In another example, nitrate has been shown to be an effective competitor of chloride uptake in soybean (Glycine max), providing a possible mechanism that could be used to alleviate chloride toxicities (Guo et al, 2017). Dhugga et al (1988) demonstrated that both nitrate and chloride uptake into excised maize roots can be inhibited by phenylglyoxal.…”

Maize NPF6 Proteins Are Homologs of Arabidopsis CHL1 That Are Selective for Both Nitrate and Chloride

Nitrate uptake by plant cells requires both high- and low-affinity transport activities. nitrate transporter 1/peptide transporter family (NPF) 6.3 is a dual-affinity plasma membrane transport protein that has both high- and low-affinity functions. At-NPF6.3 imports and senses nitrate and is regulated by phosphorylation at Thr-101 (T101). A detailed functional analysis of two maize () homologs of At-NPF6.3 (Zm-NPF6.6 and Zm-NPF6.4) showed that Zm-NPF6.6 was a pH-dependent nonbiphasic high-affinity nitrate-specific transport protein. By contrast, maize NPF6.4 was a low-affinity nitrate transporter with efflux activity. When supplied chloride, NPF6.4 switched to a high-affinity chloride selective transporter, while NPF6.6 had only a low-affinity chloride transport activity. Structural predictions identified a nitrate binding His (H362) in NPF6.6 but not in NPF6.4. Mutation of NPF6.4 Tyr-370 to His (Y370H) resulted in saturable high-affinity nitrate transport activity and nitrate selectivity. Loss of H362 in NPF6.6 (H362Y) eliminated both nitrate and chloride transport. Furthermore, alterations to Thr-104, a conserved phosphorylation site in NPF6.6, resulted in a similar high-affinity nitrate transport activity with increased, whereas equivalent changes in NPF6.4 (T106) disrupted high-affinity chloride transport activity. NPF6 proteins exhibit different substrate specificity in plants and regulate nitrate transport affinity/selectivity using a conserved His residue.

“…from being outcompeted in the rhizosphere (Guo et al, 2017). Many PGPM genera, such as Bacillus, Streptomyces, and Pseudomonas, can alleviate salt stress in soils through a variety of other mechanisms; however, this has not been investigated in aquaponic solution (Dodd and Pérez-Alfocea, 2012;Egamberdieva et al, 2019).…”

The effects of salt-induced stress in drug-type Cannabis sativa L. (C. sativa), a crop with increasing global importance, are almost entirely unknown. In an indoor controlled factorial experiment involving a type-II chemovar (i.e., one which produces D 9-tetrahydrocannabinolic acid~THCA and cannabidiolic acid~CBDA), the effects of increasing NaCl concentrations (1-40 mM) was tested in hydroponic and aquaponic solutions during the flowering stage. Growth parameters (height, canopy volume), plant physiology (chlorophyll content, leaf-gas exchange, chlorophyll fluorescence, and water use efficiency), and solution physicochemical properties (pH, EC, and nutrients) was measured throughout the experiment. Upon maturation of inflorescences, plants were harvested and yield (dry inflorescence biomass) and inflorescence potency (mass-based concentration of cannabinoids) was determined. It was found that cannabinoids decreased linearly with increasing NaCl concentration:-0.026 and-0.037% THCA•mM NaCl-1 for aquaponic and hydroponic solutions, respectively. The growth and physiological responses to NaCl in hydroponic-but not the aquaponic solutionbecame negatively affected at 40 mM. The mechanisms of aquaponic solution which allow this potential enhanced NaCl tolerance is worthy of future investigation. Commercial cultivation involving the use of hydroponic solution should carefully monitor NaCl concentrations, so that they do not exceed the phytotoxic concentration of 40 mM found here; and are aware that NaCl in excess of 5 mM may decrease yield and potency. Additional research investigating cultivar-and rootzone-specific responses to salt-induced stress is needed.
