Phylomitogenomics bolsters the high-level classification of Demospongiae (phylum Porifera). [PDF]

PLoS ONE, 2023
Class Demospongiae is the largest in the phylum Porifera (Sponges) and encompasses nearly 8,000 accepted species in three subclasses: Keratosa, Verongimorpha, and Heteroscleromorpha.

Recovering Historical eDNA From Museum-Preserved Filter Feeders via Non-Destructive Metabarcoding. [PDF]

Mol Ecol Resour
ABSTRACT Recent technical advances have significantly enhanced the value of museum specimens for molecular research, with metagenomic and metabarcoding approaches expanding further the utility of museum collections. However, given the finite number of specimens, there is a critical need to move past destructive DNA extraction approaches and to explore ...

Sex Determination in Sponges. [PDF]

Mol Reprod Dev
ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

Triterpene and Steroid Glycosides from Marine Sponges (Porifera, Demospongiae): Structures, Taxonomical Distribution, Biological Activities

Molecules, 2023
The article is a comprehensive review concerning tetracyclic triterpene and steroid glycosides from sponges (Porifera, Demospongiae). The extensive oxidative transformations of the aglycone and the use of various monosaccharide residues, with up to six ...

Direct Development of Golf Ball Sponges, Genus Craniella (Demospongiae, Tetractinellida) From the Northeast Atlantic Ocean. [PDF]

Mol Reprod Dev
ABSTRACT Among the eight types of development in sponges, the least common and least studied is direct, non‐larval development during viviparity. To supplement our knowledge of this rare type of demosponge development, we present here a description of the embryonic development of four species of the genus Craniella (Demospongiae, order Tetractinellida)

Gems From the Caves: Genomic Insights Into the Biosynthetic Potential of Antimicrobial-Producing Bacteria Associated With Tropical Cave-Dwelling Sponges. [PDF]

Environ Microbiol
Our study reveals that cave‐dwelling marine sponges host bacteria with antimicrobial activity against multidrug‐resistant strains. The bioactive Pseudomonadaceae strains exhibited biosynthetic clusters encoding both characterized and putative antimicrobial compounds and peptides. The findings highlight their potential for discovering novel biomolecules

The chromosomal genome sequence of the sponge, Rhopaloeides odorabile Thompson, Murphy, Bergquist & Evans, 1987 (Dictyoceratida: Spongiidae) and its associated microbial metagenome sequences [version 1; peer review: 2 approved] [PDF]

Wellcome Open Research
We present a genome assembly from an individual Rhopaloeides odorabile (Porifera; Demospongiae; Dictyoceratida; Spongiidae). The genome sequence has a total length of 291.63 megabases.

First draft genome assembly of sponge Halisarca dujardinii reveals key components of basement membrane and broad repertoire of aggregation factors [PDF]

Scientific Reports
How features characteristic of multicellular animals emerged in evolution is one of the key topics of modern evolutionary biology. We can get closer to answering that question by studying animals that occupy a sister taxon position to all other animals ...

Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux. [PDF]

J Exp Zool B Mol Dev Evol
Epithelia are typically ciliated, except in sponges. Of all Porifera only Homoscleromorphs have motile cilia on their epithelia. Our data highlight the presence of cilia and mucociliary particle transport as a common feature of metazoa and a secondary loss in other sponge lineages.
