| Research Abstract |
We have studied about the molecular mechanisms controlling the phototropic responses in plants. Our analyses have indicated that the blue-light photoreceptor phototropin stabilizes the signaling transducer RPT2 proteins, which are required for phototropism and degraded under the dark condition. Furthermore, we have revealed that PIN auxin efflux carriers are necessary for pulse-induced but not continuous light-induced phototropism in Arabidopsis.
