Leaf rolling phenotype
The physical curling or rolling of leaf margins inward as a mechanical response to water deficit, reducing exposed leaf surface area and transpiration rate. This visible morphological adaptation appears as an early stress symptom in many grass and crop species.
Freezing tolerance
The physiological capacity of organisms to survive intracellular and extracellular ice crystal formation without sustain...
Freezing tolerance mechanism
The physiological and biochemical adaptations that prevent ice crystal formation in cells or allow controlled extracellu...
Freezing-induced plasmolysis
The separation of cell cytoplasm from the cell wall due to ice crystal formation in intercellular spaces during freezing...
