| Outline of Final Research Achievements |
Etiolated hypocotyls of Arabidopsis seedlings show the phototropic responses in the asymmetric auxin distribution-dependent and -independent manners. We have identified the PP2C gene subfamily, which is probably involved in the asymmetric auxin distribution-independent phototropism. One of them is regulated by light irradiation transcriptionally, and another is phosphorylated in a phototropin-dependent manner. Our phosphoproteome analysis suggests that they function in the phosphorylation modification of many proteins in the etiolated seedlings.
