| trace elements found to be variable in two coral reef species, heliofungia actiniformis and galaxea fascicularis, collected from the ryukyu islands. | biominerals and metals of intertidal corals of two species (heliofungia actiniformis, quoy and gaimard; galaxea fascicularis, linnaeus), collected from the iriomote island of ryukyu, were examined with an inductively coupled plasma atomic emission spectrometer (icp-aes). twelve elements were detectable in the coralline skeletons dissected radially along the growth axis. the relative content (rc) of hg periodically fluctuated and was minimum at the hollow sites of the coralline slab of heliofungi ... | 1998 | 9881520 |
| how a host cell signalling molecule modifies carbon metabolism in symbionts of the coral plesiastrea versipora. | cnidarian cell signalling remains poorly understood. this study has expanded our knowledge of the cell signalling molecule host release factor (hrf) from the coral plesiastrea versipora. we have now confirmed that hrf is present in coral host cells that lack intracellular algae. previous studies showed that hrf stimulates the release of photosynthetic products (mainly glycerol) from symbiodinium algae, thus providing the host with carbon; glycerol release was accompanied by reduced synthesis of ... | 2013 | 23490026 |
| highly organized structure in the non-coding region of the psba minicircle from clade c symbiodinium. | the chloroplast genes of dinoflagellates are distributed among small, circular dsdna molecules termed minicircles. in this paper, we describe the structure of the non-coding region of the psba minicircle from symbiodinium: dna sequence was obtained from five symbiodinium strains obtained from four different coral host species (goniopora tenuidens, heliofungia actiniformis, leptastrea purpurea and pocillopora damicornis), which had previously been determined to be closely related using lsu rdna r ... | 2003 | 14657100 |
