Outline of Final Research Achievements

Gene expression of flowering loci for dwarf bamboo species were investigated. Flowering loci (FT) were manifested in flower bud and related tissues and also leaf tissues. The gene expression of leaves were lower than the flower buds. The sequences of flowering locus were different between two major dwarf bamboo species in genus Sasa: Sasa kurilensis and Sasa cernua. The seasonal change in FT gene expression was different between these two species. The difference was detected in flowering time and also after flowering. From these results, we should take into account that the different treatment time in management of Sasa for silviculture.
