Aspects of plant salt tolerance
High salt stress disrupts homeostasis in water potential and ion distribution. This disruption of homeostasis occurs at both the cellular and the whole-plant levels. Drastic changes in ion and water homeostasis lead to molecular damage, growth arrest and even death. To achieve salt tolerance, three interconnected aspects of plant activities are important (Fig. 1). First, damage must be prevented or alleviated. Second, homeostatic conditions must be re-established in the new, stressful
Genetic model systems
Research on salt, drought and cold tolerance has suffered from a dearth of functional genetic analysis 2., 35.. The plants that have been the favourite subjects of stress studies, such as tobacco, ice plant (Mesembryanthemum crystallinum) and tomato, are not amenable to molecular genetic analysis. As a result, most stress studies have been correlative in nature, usually comparing gene expression profiles between stressed and unstressed plants. In the absence of a good plant genetic model
