| Outline of Final Research Achievements |
DLLs genes are involved in the signaling process within statocytes in gravitropism of Arabidopsis. The genes also make the lateral shoots grow upward. AtTAC1 shows sequence similarity to DLLs except for lacking CDL sequence which is essential for molecular function of DLLs. Interestingly, AtTAC1 plays a role in downward growth of lateral shoots, that is, an opposite effect on the direction of shoot growth. Our aim is to understand how gravitropism of main axes and plageotropism of lateral shoots are unified. In this study, we determined the gene structures of DLLs family including CCP1-3 and of AtTAC1, and analyzed their physiological functions in growth angle control.
