Abstract

To date, many mutants have been isolated from dicot plants, including Arabidopsis thaliana, and the physiological roles of the isolated genes have been identified. Molecular genetic analyses have usually been conducted in the model plant Arabidopsis to identify blue-light photoreceptors and key signaling components in phototropic responses. Despite these investigations, several molecular mechanisms involved in phototropism remain unknown, possibly because detailed physiological analyses have not been conducted properly in the isolated mutants. This chapter describes an approach for the detailed investigation of hypocotyl and root phototropism in Arabidopsis seedlings. The information provided here is expected to facilitate the analysis of phototropic responses in other plant species.
