| genetic isolation among morphotypes in the photosymbiotic didemnid didemnum molle (ascidiacea, tunicata) from the ryukyus and taiwan. | didemnum molle, a colonial ascidian that harbors the symbiotic cyanophyte prochloron spp., is distributed throughout the coral reefs of the indo-west pacific ocean. several morphotypes of d. molle are characterized by the color and size of their colonies. previous molecular phylogeny inferred from gene sequences for the cytochrome oxidase subunit i (coi) identified four morphotypes (i.e., gray, brown, white, and large) from several sites in the ryukyu islands, japan. with the addition of 17 spec ... | 2010 | 21110723 |
