Review Description

Plants require substantial resistance against freezing and pathogens for overwintering. These two traits are acquired through cold acclimation. In contrast to freezing tolerance, molecular basis of disease resistance acquired through cold acclimation is poorly understood. Recent studies have suggested that pathogenesis-related (PR) proteins that are secreted into the apoplast during cold acclimation are responsible for the disease resistance. Interestingly, some of the cold-induced PR proteins display both antifungal and antifreeze activities, suggesting a dual function in protecting plants from overwintering stresses. The signaling pathway for cold-induced disease resistance is currently unknown but can be independent of pathogen-induced defense mechanisms. © The Botanical Society of Korea 2009.
