“…The “bioassay directed screening” led to another, albeit related, finding that was published recently (Yang et al, 2021). Phosphatidylinositol (PI) binds to the PM H + ‐ATPase in its low‐activity state (Table 2, Figure 4).…”

“…Furthermore, direct binding is demonstrated between recombinant AHA2 C‐terminal protein and PI using microscale thermophoresis. Here the highest affinity is found for a phospho mimic version (AHA2‐C Ser‐931Asp ) of the regulatory C‐terminal domain (Yang et al, 2021). Upon salt treatment the levels of 4‐phosphatidylinositol 4‐phosphate (PI4P) increases and the ratio between PI and PI4P changes.…”

The plant plasma membrane (PM) H + -ATPase is an essential enzyme controlling plant growth and development. It is an important factor in response to abiotic and biotic stresses and is subject to tight regulation. We are in demand for new sustainable natural growth regulators and as a key enzyme for regulation of transport into the plant cell the PM H + -ATPase is a potential target for these. In this review, we have evaluated the known non-protein natural compounds with regulatory effects on the PM H + -ATPase, focusing on their mechanism of action and their potential as biologicals/growth regulators in plant production of future sustainable agriculture.

“…The total area of salinized soil in China is about 99.13 × 10 6 hm 2 , which accounts for 1.03% of the total Chinese land area (Yang and Wang, 2015). It is expected that 50% of arable land will be under salinealkali stress by 2050 due to environmental pollution, lack of freshwater, improper irrigation methods, and other factors (Dou et al, 2019;Yang et al, 2021). Wheat (Triticum aestivum L.), one of the medium salt-tolerant crops and the secondlargest food crop in the world, also faces soil salinization in its growing area.…”

Melatonin (MT) is a small molecule indole hormone that plays an important role in the regulation of biological processes and abiotic stress resistance. Previous studies have confirmed that MT promotes the normal development of plants under stress by mediating physiological regulation mechanisms. However, the physiological mechanism of exogenous MT regulating seed germination and seedling growth of wheat under salt stress is still unclear. In this study, NaCl stress decreased germination rate and inhibited seedling growth of wheat, but shoot length, root length, and plant weight of SM15 did not change significantly. The addition of 300 μM MT in the cultivation solution directly promoted the germination rate of SM15 and ZM18, and lateral root production, but decreased the germination rate of JM22 and inhibited the length of germ and radicle of three varieties under salt stress. For wheat seedling, application of MT could increase proline content, soluble protein, soluble sugar, Ca2+ content, and vital amino acid content in leaves to keep high water content, low level of H2O2 content, and low [K+]/[Na+] ratio. MT increased root vigor and [K+]/[Na+] ratio and decreased H2O2 content in root induced by salt stress. In conclusion, MT enhanced salt tolerance in wheat seeds and seedlings by regulating the synthesis of soluble protein and sugar, ion compartmentation in roots and leaves, enhancement of enzymatic systems, and changes in amino acid levels. Salt resistance varied with different varieties under the same environmental condition. SM15 was a higher salt-resistant variety and JM22 was a salt-sensitive one. In wheat production, the application of exogenous MT should consider the differences among varieties of wheat during the sowing and seedling stages.

“…However, salt stress does induce the turnover of PI to PI4P, which in turn stimulates SOS1 activity to exclude excess Na + from the cell. This turnover is genetically evidenced by the PI synthase mutations pis1-1 and pis1-2, which feature a reduced PI level and the salt-tolerant phenotype, and also by the PI4P synthase mutation pi4kβ1, which has a reduced PI4P level and the salt-sensitive phenotype [92]. Our study reveals that the metabolic turnover of PIs plays a key role in salt stress response.…”

“…In this way, they can communicate with other molecules; an example of this is the interaction between PA and the salt signaling proteins PINOID mentioned above [6]. Besides PA interacting with proteins, other phospholipidinteracting proteins were also identified, such as the interaction mentioned above between PI and the C-terminus of PM H + -ATPase [92], PI4P and SOS1 [92], PI4P and PUB13 [106], PI3P and ROF1 [141]. Based on this point, the regulatory role of phospholipids in salt stress is to a certain extent dependent on their binding proteins, such as the regulatory role of PA in salt stress depending in part on its interacting protein PINOID [6].…”

High salinity threatens crop production by harming plants and interfering with their development. Plant cells respond to salt stress in various ways, all of which involve multiple components such as proteins, peptides, lipids, sugars, and phytohormones. Phospholipids, important components of bio-membranes, are small amphoteric molecular compounds. These have attracted significant attention in recent years due to the regulatory effect they have on cellular activity. Over the past few decades, genetic and biochemical analyses have partly revealed that phospholipids regulate salt stress response by participating in salt stress signal transduction. In this review, we summarize the generation and metabolism of phospholipid phosphatidic acid (PA), phosphoinositides (PIs), phosphatidylserine (PS), phosphatidylcholine (PC), phosphatidylethanolamine (PE) and phosphatidylglycerol (PG), as well as the regulatory role each phospholipid plays in the salt stress response. We also discuss the possible regulatory role based on how they act during other cellular activities.
