| Outline of Final Research Achievements |
When considering efficient use of wood, existence of reaction wood becomes a problem. Reaction wood is a special tissue that is formed during secondary growth in an inclined stem. In the reaction wood region, high growth stress is generated and it causes cracks and warp at the time of cross cutting and lumbering. This study aimed to understand a mechanism of the reaction wood formation of conifers from a viewpoint of gene expression. The gene expression of mechanosensitive channels, which respond to external mechanical stimuli and change the concentration of calcium ion within the cells, were focused on. The results showed that the gene expression patterns within the stems had changed when the stimuli of inclination and bending were applied to the stems.
