Outline of Final Research Achievements

To understand the early step of cold-deacclimation process in boreal trees, changes in proteins in artificially-deacclimated twigs of Betula platyphylla and seasonally-deacclimated twigs of Populous nigra were investigated.
In this research, semiquantitative data on the contents of more than 2,000 independent proteins in twigs of boreal trees during deaccliamation were collected. These data indicated the involvement of other factors, including changes in protein localization, than de novo protein synthesis in the early step of deacclimation process.
