Species Diversity and Secondary Metabolites of Sarcophyton-Associated Marine Fungi

Molecules, 2021
Soft corals are widely distributed across the globe, especially in the Indo-Pacific region, with Sarcophyton being one of the most abundant genera. To date, there have been 50 species of identified Sarcophyton.

Octocorals in the Gulf of Aqaba exhibit high photosymbiont fidelity. [PDF]

Front Microbiol, 2022
Symbiotic associations, widespread in terrestrial and marine ecosystems, are of considerable ecological importance. Many tropical coral species are holobionts, formed by the obligate association between a cnidarian host and endosymbiotic dinoflagellates of the family Symbiodiniaceae.

Actions of octocoral and tobacco cembranoids on nicotinic receptors [PDF]

Toxicon, 2009
Nicotinic acetylcholine receptors (AChRs) are pentameric proteins that form agonist-gated cation channels through the plasma membrane. AChR agonists and antagonists are potential candidates for the treatment of neurodegenerative diseases. Cembranoids are naturally occurring diterpenoids that contain a 14-carbon ring.

Host-microbe interactions in octocoral holobionts - recent advances and perspectives

Microbiome, 2018
Octocorals are one of the most ubiquitous benthic organisms in marine ecosystems from the shallow tropics to the Antarctic deep sea, providing habitat for numerous organisms as well as ecosystem services for humans.

Mitogenomic phylogenetic analyses of Leptogorgia virgulata and Leptogorgia hebes (Anthozoa: Octocorallia) from the Gulf of Mexico provides insight on Gorgoniidae divergence between Pacific and Atlantic lineages

Ecology and Evolution, 2019
The use of genetics in recent years has brought to light the need to reevaluate the classification of many gorgonian octocorals. This study focuses on two Leptogorgia species—Leptogorgia virgulata and Leptogorgia hebes—from the northwestern Gulf of ...

Grazers and predators mediate the post-settlement bottleneck in Caribbean octocoral forests

Frontiers in Marine Science
In the Caribbean, reef-building scleractinian corals have declined precipitously and octocorals have emerged as one of their main successors. The success of octocorals and the formation of octocoral forests has been attributed to their continuing ...

Know Thy Anemone: A Review of Threats to Octocorals and Anemones and Opportunities for Their Restoration

Frontiers in Marine Science, 2020
In studies of habitat-forming species, those that are not spatially dominant are often considered “non-primary” habitat and may be overlooked. This is despite the fact that minority habitat formers can provide critical complexity, food, and other ...

Polyoxygenated Steroids from the Octocoral Leptogorgia punicea and in Vitro Evaluation of Their Cytotoxic Activity

Marine Drugs, 2014
Five new polyoxygenated marine steroids—punicinols A–E (1–5)—were isolated from the gorgonian Leptogorgia punicea and characterized by spectroscopic methods (IR, MS, 1H, 13C and 2-D NMR). The five compounds induced in vitro cytotoxic effects against lung

The Genome Sequence of the Octocoral Paramuricea clavata – A Key Resource To Study the Impact of Climate Change in the Mediterranean

G3: Genes, Genomes, Genetics, 2020
The octocoral, Paramuricea clavata, is a habitat-forming anthozoan with a key ecological role in rocky benthic and biodiversity-rich communities in the Mediterranean and Eastern Atlantic. Shallow populations of P.
