| Outline of Final Research Achievements |
To investigate the function and the action mechanism of sex pheromone (gamone) in ciliate Blepharisma, ①Isolated gamone 1 genes from several stocks of Blepharisma and identified the sites which determine the specificity of species, ② examined the localization of gamone receptors in the cells, ③ tried to identify genes involved in biosynthesis of gamone 2. In order to clarify the phylogenetic relationship of the strains of Blepharisma, ④ isolated several genes and constructed phylogenetic trees, and ⑤ investigated the specificity of gamone 1 between species, whether the pair formation between different megakaryotype strains and between different species occrred, and whether progenies between such crosses survived, and reexamined the classification of the genus Blepharisma.
