With the continuous growth of the global population and economic development, the population-environment-resources problems faced by the world are becoming more and more serious, the pressure on land bearing is increasing, and the problem of soil degradation is becoming more and more prominent. Among them, soil salinization is an increasingly serious problem. It is estimated that the global saline-alkali land is growing at a rate of 1×106 - 1.5×106 ha per year. Especially in coastal areas, a large number of tidal flats are formed every year due to natural deposition or artificial reclamation and gradually evolve into saline-alkali land, in which generally there are few halophytes such as Suaeda glauca, S. salsa, and Salicornia europaea, etc. growing due to the adverse soil conditions. In order to relieve the population pressure, improve the ecological environment of the saline-alkali land, better develop and utilize the saline-alkali land, and make it an important potential land resource, it is necessary to implement ecological restoration of the saline-alkali land. From an ecological point of view, the fundamental way to manage saline-alkali land is to use the principle of ecosystem control to carry out the ecological restoration of saline-alkali land, restore vegetation, and improve soil structure. The key measure is the selection of salt-tolerant plants, which is scientifically based on figuring out the adaptation and resistance mechanisms of plants under saline-alkali stress.
In order to make good use of saline-alkali land as an important reserve land resource, the selection of salt-tolerant plant materials is a necessary condition based on the implementation of ecological restoration. By exploring the mechanisms of plants’ responses to saline-alkali stress, it is also important to improve the salt-tolerant ability of plants and breed new salt-tolerant plants. This Research Topic intends to probe the effects of salt stress on plants' growth and physiological activities and to understand the salt tolerance and growth laws of plants grown in sodic soils and coastal saline lands. We welcome articles that provide up-to-date and in-depth scientific knowledge on revealing the ion regulation and the physiological and biochemical responses of plants under salt stress, elucidating the "switch" of metabolic activities adapted to salt stress, and preliminarily analyzing the mechanism of salt tolerance, which would benefit to the breeding of new salt-tolerant plants and improve their tolerance capacity in the future.
For this Research Topic the following themes will be covered such as:
- The physiological and biochemical activities of different plants in saline-alkali land, such as salted sea beaches, saline sodic land, discarded salkaline land, salinized grassland, etc.
- Mechanisms of adaptive responses of plants to salt stress through ion regulation
- Possible signal transmission (e.g. immunogenic signals, chemical signals and hormone salicylic acid (SA)) of plants under salt stress
- The role of growth regulators in enhancing salt tolerance
- Environmental effects on plant adaptation capacity such as drought, high temperature, salinized and easily waterlogged low land, percolating water, etc.
