Outline of Final Research Achievements |
Mussels, known as major fouling animals in the sea, can change position by cutting byssus, the attachment apparatus, after they attached to a substrate. The purpose of this study is to contribute to the development of new anti-biofouling methods, by identifying the conditions that can induce the translocation and also the mechanisms to cut the byssus. Results of exposure experiments to various conditions (temperature, salinity, air exposure, existence of predators, etc.) suggested that some conditions induce translocation but some other conditions rather induce withdrawal into their shells. When they cut the byssus, two different methods were observed; one is just to tug a single byssus and the other is to digest the stem connecting multiple byssi. Cloning of cDNAs encoding enzymes that may be involved in stem digestion were also conducted.
