| Outline of Final Research Achievements |
Abnormal enlargement of the ovary in Pacific oyster, Crassostrea gigas, is characterized as development of the ovary and active oogenesis after the regular spawning season of Pacific oyster. This unusual physiological condition is considered to be induced and regulated by a protozoan parasite, Marteilioides chungmuensis, which sporulates in oocyte of Pacific oyster, but its mechanisms has not been fully elucidated. In the present study, transcriptome data were sucessfully accumulated from the ovaries infected with the causative protozoan parasite. Based on these data, it was revealed that the gene expression profiles of the infected ovary were obviously different from uninfected/normal ovary, suggesting that information collected from this project will be useful to understand both the targeted phenomenon and the bivalve reproduction systems.
