About this Research Topic
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.
Keywords: physiological activities, salt stress, signal transmission, ion regulation
