Interpretive Summary:

Technical Abstract: Phenotypic studies have shown that cold acclimation in wheat and its relatives start at different temperatures. To gain insight into the underlying mechanisms that regulate the induction of cold-acclimation process in cereals we compared the expression of genes in winter-habit (winter Norstar and winter Manitou) and spring-habit (spring Manitou and spring Norstar) cultivars that vary in tolerance to cold. Global expression of genes in the crowns of juvenile plants cold-acclimated at four different temperatures (6o C, 9 oC, 12o C, 15 oC and 18 oC) for 12-hrs, 60-hrs and 380-hrs was examined. Expression of genes associated with induction of cold-acclimation at different temperatures will be presented.
