5. Relationship between Freezing Tolerance in Plant and the Stability of the Plasma Membrane during Freeze-Induced Dehydration(the 45th Annual Meeting)

Abstract

Effect of lipid alterations in the chloroplast envelope, manipulation of cytosolic sugar content, and expression of the cold-regulated (COR) genes on the cryostability of the plasma membrane was determined. All of these three factors were shown to contribute to the increase in the cryostability of the plasma membrane during freeze-induced dehydration, which consequently results in an increase in the freezing tolerance. The results suggest that the action mechanism (s) of each factor to increase the cryostability of the plasma membrane must be determined in detail.
