Abstract excerpt
Overwintering plants develop tolerance to freezing stress through a cold acclimation process by which the cells provoke internal protective mechanisms against freezing. The stress hormone abscisic acid (ABA) is known to increase freezing tolerance of plant cells, but its role in cold acclimation has not been determined. In this study, we used ABA-insensitive lines of the moss Physcomitrella patens to determine...
