“…The symplastic transport of NaCl through transporters and channels has been well known in the cells of animals, plants and algae. These ion channels play a crucial role in the total uptake of ions inside cells (Saibi and Brini, 2021). It was observed that in guard cells, the inward K + channels can remain active for more than half an hour.…”

Soil salinity is one of the most serious threats to plant growth and productivity. Due to global climate change, burgeoning population and shrinking arable land, there is an urgent need to develop crops with minimum reduction in yield when cultivated in salt‐affected areas. Salinity stress imposes osmotic stress as well as ion toxicity, which impairs major plant processes such as photosynthesis, cellular metabolism, and plant nutrition. One of the major effects of salinity stress in plants includes the disturbance of ion homeostasis in various tissues. In the present study, we aimed to review the regulation of uptake, transport, storage, efflux, influx, and accumulation of various ions in plants under salinity stress. We have summarized major research advancements towards understanding the ion homeostasis at both cellular and whole‐plant level under salinity stress. We have also discussed various factors regulating the function of ion transporters and channels in maintaining ion homeostasis and ionic interactions under salt stress, including plant antioxidative defense, osmo‐protection, and osmoregulation. We further elaborated on stress perception at extracellular and intracellular levels, which triggers downstream intracellular‐signaling cascade, including secondary messenger molecules generation. Various signaling and signal transduction mechanisms under salinity stress and their role in improving ion homeostasis in plants are also discussed. Taken together, the present review focuses on recent advancements in understanding the regulation and function of different ion channels and transporters under salt stress, which may pave the way for crop improvement.

“…Mechanisms were proposed to work in sequences, one at the plasmalemma and one at the vacuolar membrane or tonoplast (Laties, 1969;Alaoui et al, 2022). Uptake mechanisms go on unaffected over varied concentration series, but their features adjust at definite distinct outside concentrations (Nissen, 1974;Le Deunff et al, 2016;Saibi and Brini, 2021). Ion absorption data were revisited in many plant species and it was concluded that ion uptake in higher plants can be explained by multiphasic mechanisms which account for ostensible opposing evidence for analogous and sequence models (Nissen et al, 1980;Wang et al, 2023).…”

Nutrient demands of plants are fulfilled via nutrient uptake by the roots, even though minor quantities of certain nutrients might be assimilated via leaves. For the reason that the majority of nutrients are assimilated by roots, an understanding of root morphology and cell structure is crucial in knowing this basic plant process. Nutrient achievement by plants hinges on ion applications on superficial, root assimilation capacity, and plant requirement. Movement of ion in plant cells is classified into active and passive. Ion concentrations in the cytoplasm of plant cells are frequently and considerably observed to be greater than in soil solutions. Consequently, roots ought to be able to take up ions in contrast to broadly diverse concentration gradients. Currently, two major theories of ion transport across membranes are reported in literature: carrier theory where carrier agents accountable for transferring ions from one side of membrane to the other; encounter specific ions for which they have attraction, form carrier ion complexes; and move across membranes and connecting ATPase theory of ion transport; which is related with the plasmalemma and is activated by cations; the ion pump theory, which is a demanding proces, transporting via electrochemical gradient. Measurements of ion uptake could be achieved through tracer techniques. Long-distance transport of ions to shoots happens in the vascular system, with water being the transporting agent. New and stimulating developments in mineral uptake mechanism of plants have momentously added to our understanding of the function of nutrients uptake in plants. Most research comparative to physiology of nutrient uptake has been conducted under controlled environment by means of particular nutrient cultures in the growth medium.

“…K + ions are associated with reactive oxygen species (ROS) detoxification under various abiotic stresses (Anil Kumar et al, 2022). The key instrument for achieving cell homeostasis in saline stress conditions is maintaining Na + and K + transporters and channel activity (Saibi and Brini, 2021) and the coordinated work of several K + channels and transporters (Mostofa et al, 2022). Transcription of genes related to ion homeostasis serves as the primary regulator under saline conditions (Parvaiz and Satyawati, 2008).…”

Global climate change presents various challenges to agricultural biotechnology in developing crops with increased resilience to various adverse natural conditions. Given the importance of this problem, we explored the mechanisms of plant salt tolerance and the role of plant-associated microbes, in mediating important physiological and metabolic processes that increase plant resistance to salt stress. Understanding the physiological, metabolic, and molecular responses of the entire plant holobiont, primarily including microorganisms, to the combination of abiotic stresses may be the key to developing more effective methods of combating various stress conditions and increasing agricultural efficiency. This work encompassed 86 peer-reviewed articles focused on various aspects of plant development in saline conditions and especially on key mechanisms of mitigating stress conditions, including the role of rhizobiome and endophytic microorganisms. It is shown that host plants and various microorganisms can form complex relationships where each organism plays a specific role in forming tolerance to stress conditions. Our review proposes that studying microorganisms that are resistant to soil salinity can lead to the development of new strategies to combat salinization and improve crop stress resistance. The paper concludes that using salt-adapted biostimulant microorganisms, which are natural components of agricultural plant microbiomes, is a highly promising research area.
