Outline of Final Research Achievements

In this study, we analied flower movement under circadian clock. There are 3 of newly idenfified circadian flower movement mutants. These 3 mutants showed loss of flower closing and remarkable abnormality in circadian clock gene expression (CCA1, LHY1, and TOC1), suggesting the causative gene is a circadian clock gene. Genetic mapping experiment suggested the loacation of the mutation between 2 genetic molecular markers. There is no reported circadian clock gene in the genomic region. Whole genome sequencing analisis of the flower movement mutants determined several substitutions of base-pair among the suggested genetic marker region.
