Research Abstract |
Drought stress and accumulation of salt lead to increase the osmolarity of the environmental space. This gave the dehydration of plant cells, which ends up to jeopardize the plant life. The water movement across the biological membrane is affected by osmolarity and therefore the concentrations of cation, sodium ion and potassium ion are crucial for them. The intracellular concentrations of these cation play an important role in ion homeostasis in plant cells. In this study, membrane transport system for sodium ion and potassium ion has been analyzed and their structure and function has been investigated. The increase of the resistance against the environmental stress in plant cells has been studied through the elucidation of their sodium and potassium transport system, which is closely involved in understanding the molecular mechanism of osmolarity homeostasis.
