| Outline of Final Research Achievements |
I studied about “how heterocyst cells are differentiated at almost every 10 cells along a filament in a multicellular cyanobacterium”. First, I measured Raman spectra from vegetative and heterocyst cells, and found that Raman bands were assigned to four kinds of photosynthesis proteins. Especially, the Raman bands assigned to phycocyanin were gradually decreased during the heterocyst differentiation. Second, such changes in the Raman band intensities were observed in adjacent several vegetative cells. When any one cell was selected to be differentiated, the Raman bands assigned to phycocyanin were reversely increased in other cells. That is, we showed that the cellular fate is determined thorough the cellular interaction by measuring the Raman bands assigned to the photosynthesis proteins.
