Plant salt response: Perception, signaling, and tolerance
In general, there are two plant types regarding their distinct salt tolerance. Some plants, termed halophytes, naturally grow in or even adapt to the saline environment with more than 200 mM NaCl (Duarte et al., 2014).By contrast, most other plant species are salt-sensitive glycophytes, and their growth and development are adversely inhibited by …
