Outline of Final Research Achievements |
Loss of arabinosyl residues from cell wall polysaccharides was observed in petals of carnation, rose and Eustoma during flower opening. Concomitantly, an increase in α-arabinofuranosidase activity was observed. At least nine α-arabinofuranosidase genes are present in carnation, the expression of two of them coincided with increase of the activity. When xyloglucan derived oligosaccharides were absorbed together with water, the flowering was promoted in carnation and chrysanthemum. It was suggested that water influx by aquaporin, degradation of arabinose-containing cell wall matrix and restructuring of xyloglucan occurred in flower opening of carnation.
