| Outline of Final Research Achievements |
Aureochrome is a blue-light receptor possessed only in photosynthetic stramenopiles. They contain diverse algae, such as diatoms, brown algae and red tide algae, and it has been reported that photomorphogenesis and photomovement are induced by blue light. In the present, we focused on aureochrome- dependent physiological responses and acquisition of transcript information by new generation sequencing in brown algae. In the two brown algae, blue-light-dependent the thallus formation and transition to sexual phase were observed. As a result of transcriptome, we found that brown algae have a number of aureochrome homologs and the homologs are divided into three groups by phylogenetic analysis. When we analyzed the gene expression profiles of aureochromes and other transcripts under various light conditions, differences in the level of expression between orthologs of aureochromes were confirmed. Furthermore, we also found the regulation of expression of some genes under various light.
