| Outline of Final Research Achievements |
Diurnal periodicity in wood cell wall formation in a conifer, Cryptomeria japonica, was investigated at the gene level. In differentiating xylem of C. japonica saplings, diurnal changes in expression of some genes involved in cellulose biosynthesis were observed. Clear diurnal patterns of gene expression involved in hemicellulose biosynthesis were not observed, while diurnal changes in expression of some genes involved in secretion of hemicelluloses via exocytosis were observed. These results suggest a possibility that diurnal periodicity in cellulose biosynthesis and hemicellulose secretion exists during wood cell wall formation. It seems probable that diurnal changes in gene expression are associated with diurnal periodicity in wood cell wall formation.
