RNA interference in marine and freshwater sponges [PDF]

open access: yes, 2011
Background: The marine sponge Tethya wilhelma and the freshwater sponge Ephydatia muelleri are emerging model organisms to study evolution, gene regulation, development, and physiology in non-bilaterian animal systems. Thus far, functional methods (i.e.,

The early expansion and evolutionary dynamics of POU class genes. [PDF]

open access: yes, 2014
The POU genes represent a diverse class of animal-specific transcription factors that play important roles in neurogenesis, pluripotency, and cell-type specification. Although previous attempts have been made to reconstruct the evolution of the POU class,

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

open access: yesBMC 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.

Seasonal Growth Rate of the Sponge Haliclona oculata (Demospongiae: Haplosclerida) [PDF]

open access: yes, 2008
The interest in sponges has increased rapidly since the discovery of potential new pharmaceutical compounds produced by many sponges. A good method to produce these compounds by using aquaculture of sponges is not yet available, because there is ...

A Metataxonomic Approach Reveals Diversified Bacterial Communities in Antarctic Sponges

open access: yesMarine Drugs, 2021
Marine sponges commonly host a repertoire of bacterial-associated organisms, which significantly contribute to their health and survival by producing several anti-predatory molecules. Many of these compounds are produced by sponge-associated bacteria and

Microbial communities and bioactive compounds in marine sponges of the family Irciniidae-a review [PDF]

open access: yes, 2014
Marine sponges harbour complex microbial communities of ecological and biotechnological importance. Here, we propose the application of the widespread sponge family Irciniidae as an appropriate model in microbiology and biochemistry research. Half a gram
