| Outline of Final Research Achievements |
It has been recognized that hinoki (Chamaecyparis obtusa) has a characteristic that generally rooting difficult. We focused on cutting cultiver 'Nangouhi' with superior originating nature in rooting ability and investigated whether differences in expression genes can be seen between 'Nangouhi' and ordinary hinoki to detect the root-inducing candidate genes.
In the results of the RNA sequences, it was possible to collect 148,163 of expression genes which are believed to be related to rooting after cuttings. Examination of the nucleotide sequence similarity with rooting related candidate genes of Arabidopsis, 90 genes showed similarity to sequences of hinoki. In between 'Nangouhi' and ordinary hinoki, there were differences in the amount of expression level in the 1,312 genes. Many of them were related to the stress response and the signal transduction.
