Draft genomes shed light on the dual bacterial symbiosis that dominates the microbiome of the coral reef sponge Amphimedon queenslandica

Frontiers in Marine Science, 2016
Amphimedon queenslandica is a coral reef demosponge that houses a low complexity and low abundance microbiota dominated by a proteobacterial duo for which draft genomes are presented here.

The complete mitochondrial genome of sponge Halichondria sp. (Demospongiae, Suberitida, Halichondriidae) from Dok-do

Mitochondrial DNA. Part B. Resources, 2019
The mitogenome sequence of Halichondria sp. was determined for the first time in this study. Specimens were identified as a new species belonging to genus Halichondria and more detailed taxonomic study is ongoing.

Divergence times in demosponges (Porifera): first insights from new mitogenomes and the inclusion of fossils in a birth-death clock model

BMC Evolutionary Biology, 2018
Background Approximately 80% of all described extant sponge species belong to the class Demospongiae. Yet, despite their diversity and importance, accurate divergence times are still unknown for most demosponge clades.

The complete mitochondrial genome of sponge Pseudosuberites sp. (Demospongiae, Suberitida, Suberitidae) from Dokdo, Republic of Korea (East Sea)

Mitochondrial DNA. Part B. Resources, 2019
The mitogenome of Pseudosuberites sp. (Suberitida, Suberitidae) has been determined first in the genus Pseudosuberites. Assembled mitogenome was 23,502 bp in length, including 14 protein-coding genes, 25 transfer RNA, and 2 ribosomal RNA genes. The order

Sponge Takeover from End-Permian Mass Extinction to Early Induan Time: Records in Central Iran Microbial Buildups

Frontiers in Earth Science, 2021
The end-Permian mass extinction was the most severe biotic crisis in Earth’s history. In its direct aftermath, microbial communities were abundant on shallow-marine shelves around the Tethys.

Taxonomical and biogeographical notes on the sponges of the Strait of Magellan

Scientia Marina, 1999
The sponge material from the Straits of Magellan collected by the research vessels Cariboo in 1991 and Victor Hensen in 1994, and by a shallow water diving team, were studied.

Syntheses of porphyrins isolated from the Coral Sea demosponge Corallistes sp.

ARKIVOC, 2002
Methyl esters 2, 3, and 5 of corallistins B, C, and E, respectively, isolated from the Coral Sea demosponge Corallistes sp., were successfully synthesized by the MacDonald method (for corallistin B ester) and via a,c-biladiene cyclization (for ...

A horizontal gene transfer supported the evolution of an early metazoan biomineralization strategy

BMC Evolutionary Biology, 2011
Background The synchronous and widespread adoption of the ability to biomineralize was a defining event for metazoan evolution during the late Precambrian/early Cambrian 545 million years ago.

Antifouling activity of twelve demosponges from Brazil [PDF]

Brazilian Journal of Biology, 2013
Benthic marine organisms are constantly exposed to fouling, which is harmful to most host species. Thus, the production of secondary metabolites containing antifouling properties is an important ecological advantage for sessile organisms and may also provide leading compounds for the development of antifouling paints.

Discovery of missing link between demosponges and hexactinellids confirms palaeontological model of sponge evolution

Scientific Reports, 2017
The two major extant groups of siliceous sponges, Demospongiae and Hexactinellida, are generally regarded as sister groups forming the clade Silicea, although the nature of their last common ancestor is uncertain.
