Technical Abstract: Exposure of woody plants to near-lethal stresses during endodormancy can reduce the level of cold hardiness and result in plant dieback and/or earlier budbreak. The impact of near-lethal stresses on temperate woody plants under natural conditions is poorly understood. Our research indicates that near-lethal stresses may help to explain, in some instances, occurrences of plant dieback in temperate zones, the failure of predictive models for timing of budbreak of temperate woody plants, and the unexpected early and/or delayed spring budbreak of temperate plants. Although numerous stress-induced proteins, as well as their corresponding genes, have been reported in the literature for herbaceous plants, little is known about their existence in woody plants. The use of near-lethal stresses offers an excellent opportunity to make progress in understanding the biochemical and molecular basis for dormancy in woody plants. Although several proteins have been associated with changes in dormancy status, the direct relation of these proteins to either endodormancy or near-lethal stress physiology remains to be elucidated.
