| Outline of Final Research Achievements |
FT gene from Japanese beech tree (Fagus crenata) (FcFT) transcripts increased in the leaves of flowered branches a year before. The result suggests application of FcFT gene expression pattern as prediction indicator of flowering following year, by measuring FcFT gene expression. E-box motif induced by blue light and motifs induced by white light were identified from FcFT gene regulated promoter sequences. Arabidopsis PIF4 homologue FcPIF3 expression pattern was positively correlated with FcFT expression. This correlation suggests that FcPIF4 transcript directly induce FcFT gene as formerly reported in Arabidopsis. Several proteins in which their production amounts are influenced by temperature were also identified by proteomics analysis.
