当植物细胞遭受细胞外冷冻时，质膜被认为是主要的损伤部位。因此，为了使植物或植物细胞获得耐寒性，质膜必须在冻融漂移过程中增加其低温稳定性。在自然和人工条件下的冷驯化过程中，质膜的组成、结构和功能发生了变化，其中许多（如果不是全部的话）最终有助于提高质膜在冷冻条件下的稳定性。此外，细胞质溶胶或细胞内区室的变化也会影响在冷冻脱水过程中质膜的低温行为。尽管在冷驯化过程中发生的许多变化会全面影响质膜的低温行为，但功能基因组学方法的最新进展为在冷冻条件下质膜行为的特定蛋白质的功能提供了有趣的信息。
The plasma membrane is considered to be the primary site of injury when plant cells are subjected to extracellular freezing. In order for plants or plant cells to acquire freezing tolerance, it is, thus, necessary that the plasma membrane increases its cryostability during freeze-thaw excursion. During cold acclimation both under natural and artificial conditions, there are compositional, structural and functional changes occurring in the plasma membrane, many, if not all, of which ultimately contribute to increased stability of the plasma membrane under freezing conditions. In addition, changes in the cytosol or intracellular compartments also affect the cryobehaviour of the plasma membrane during freeze-induced dehydration. Although many alterations occurring during cold acclimation influence the cryobehaviour of the plasma membrane comprehensively, recent advances in functional genomics approaches provide interesting information on the function of specific proteins for plasma membrane behaviour under freezing conditions.
