Abstract:
Plants from temperate and cold climates are able to increase their freezing tolerance during exposure to low non-freezing temperatures. It has been shown that several genes are induced in a coordinated manner during this process of cold acclimation. The functional role of most of the corresponding cold-regulated proteins is not yet known. We summarize our knowledge of those cold-regulated proteins that are able to stabilize membranes during a freeze-thaw cycle. Special emphasis is placed on cryoprotectin, a lipid-transfer protein homologue that was isolated from cold-acclimated cabbage leaves and that protects isolated chloroplast thylakoid membranes from freeze-thaw damage.
