| Research Abstract |
We searched coral lectins involved in the acquisition of Symbiodinium. A lectin SLL-2 purified from Sinularia lochmodes transform Symbiodinium to the coccoid form which is similar to symbiotic form of them. This resulted from binding of SLL-2 to the Forssman like glycosphingolipid on the surface of Symbiodinium. A lectin from Ctenactis echinata attracted Symbiodinium which can symbiose with the coral. The lectin from Acropora tenuis involved in the acquisition of Symbiodinium. These indicated that The acquisition mechanism of Symbiodinium by corals has at least two steps, attraction and acquisition.
