| montiporic acids a and b, cytotoxic and antimicrobial polyacetylene carboxylic acids from eggs of the scleractinian coral montipora digitata. | two new polyacetylene carboxylic acids, montiporic acids a (1) and b (2), have been isolated from the eggs of the scleractinian coral montipora digitata and their structures elucidated on the basis of spectroscopic data. they exhibited antimicrobial activity against escherichia coli and cytotoxicity against p-388 murine leukemia cells. | 1996 | 8792626 |
| isolation and primary culture of viable multicellular endothelial isolates from hard corals. | conditions for the primary culture of branching scleractinian coral (acropora micropthalma and pocillopora damicornis) cells were established with a calcium-free seawater cell dissociation method. cells were isolated and cultured in supplemented dulbecco's modified eagle media with heat-inactivated fetal bovine serum, antibiotics, and sterile seawater. among the isolated cell types, large (60-100 microm) multicellular endothelial isolates (meis) were seen in high numbers. these isolates were obs ... | 1999 | 10614872 |
| monitoring of heavy metal partitioning in reef corals of lakshadweep archipelago, indian ocean. | this paper focuses on the partitioning of trace metals in five selected coral species from lakshadweep archipelago, which remains as one of the least studied areas in the indian ocean. based on the morphological features, selected coral species are classified as massive (porites andrewsi), ramose or branching (lobophyllia corymbosa, acropora formosa and psammocora contigua) and foliaceous (montipora digitata). relating trace metal concentrations with morphological features in skeleton, highest c ... | 2007 | 17016753 |
| chromera velia is endosymbiotic in larvae of the reef corals acropora digitifera and a. tenuis. | scleractinian corals occur in symbiosis with a range of organisms including the dinoflagellate alga, symbiodinium, an association that is mutualistic. however, not all symbionts benefit the host. in particular, many organisms within the microbial mucus layer that covers the coral epithelium can cause disease and death. other organisms in symbiosis with corals include the recently described chromera velia, a photosynthetic relative of the apicomplexan parasites that shares a common ancestor with ... | 2013 | 23063731 |
| colony-specific investigations reveal highly variable responses among individual corals to ocean acidification and warming. | as anthropogenic climate change is an ongoing concern, scientific investigations on its impacts on coral reefs are increasing. although impacts of combined ocean acidification (oa) and temperature stress (t) on reef-building scleractinian corals have been studied at the genus, species and population levels, there are little data available on how individual corals respond to combined oa and anomalous temperatures. in this study, we exposed individual colonies of acropora digitifera, montipora dig ... | 2015 | 26009841 |
| differential coral bleaching-contrasting the activity and response of enzymatic antioxidants in symbiotic partners under thermal stress. | mass coral bleaching due to thermal stress represents a major threat to the integrity and functioning of coral reefs. thermal thresholds vary, however, between corals, partly as a result of the specific type of endosymbiotic dinoflagellate (symbiodinium sp.) they harbour. the production of reactive oxygen species (ros) in corals under thermal and light stress has been recognised as one mechanism that can lead to cellular damage and the loss of their symbiont population (oxidative theory of coral ... | 2015 | 26310104 |
| gene expression of corals in response to macroalgal competitors. | as corals decline and macroalgae proliferate on coral reefs, coral-macroalgal competition becomes more frequent and ecologically important. whether corals are damaged by these interactions depends on susceptibility of the coral and traits of macroalgal competitors. investigating changes in gene expression of corals and their intracellular symbiotic algae, symbiodinium, in response to contact with different macroalgae provides insight into the biological processes and cellular pathways affected b ... | 2014 | 25500576 |
| identification of a novel yolk protein in the hermatypic coral galaxea fascicularis. | the reef-building (or hermatypic) coral galaxea fascicularis (anthozoa, hexacorallia, scleractinia) has an annual reproductive cycle. females of g. fascicularis release packages (or ;bundles') of eggs for external fertilization, whereas male individuals form bundles consisting of sperm and infertile ;pseudo-eggs' that are thought to confer buoyancy to the male bundle. in the egg of g. fascicularis, four proteins (gfep-1 to 4) were found to be stored in high abundance, and three of them (gfep-1, ... | 2007 | 17551245 |
