Many plants accumulate compatible solutes in response to the imposition of environmental stresses.Glycine betaine, which is one of compatible solutes in cell of plants,has been shown to have surviving ability for plant from salt stress.Effect of glycine betaine on improving plant salt resistance was discussed in plants under salt stress.The accumulation of glycine betaine protects plants against the damaging effects of stress.Strategies of glycine betaine against the damaging effects of stress were analyzed to clarify the roles of glycine betaine in salt stress tolerance of plants.
