Natural genetic variation in acclimation capacity at sub-zero temperatures after cold acclimation at 4 degrees C in different Arabidopsis thaliana accessions.

Abstract excerpt

Freezing tolerance is an important factor in the geographical distribution of plants and strongly influences crop yield. Many plants increase their freezing tolerance during exposure to low, nonfreezing temperatures (cold acclimation) and acclimation may continue at mild freezing temperatures in a process termed sub-zero acclimation. There is considerable natural variation in the cold acclimation capacity of...
