Outline of Final Research Achievements

In this study, we identified that plant histones are glycosylated by a sugar chain having N-acetylglucosamine in the non-reducing end. This is the first report on the glycosylation of plant histones, and it indicates that glycosylation might play an epigenetic role in plants.
We also identified that acetylation of α-tubulin is a widespread post-translational modification in angiosperms, and we characterized regulated changes in acetylation of α-tubulin during the growth and the organ development of Fast Plants.
