| Outline of Final Research Achievements |
In this study, we have sampled multi-organ (apical-shoot, needle-leaf, cambium) from single tree throughout a year, and then constructed a gene expression network using microarray analysis, which can examine the expression levels of several tens of thousands of genes at the same time. In gene expression data, there were gene groups that do not indicate fluctuation regardless of organ or time, on the other hand, two fluctuation gene expression trends were indicated. Firstly, gene expression pattern was divided into two groups as the cambium group and apical-shoot/needle-leaf group. These findings suggest that difference among two groups indicated in functional difference in tissue. Secondly, gene expression pattern in each group was split into the growing season and dormant season.
