Marine Sponges and Natural Products

This study investigates microbial changes in sponge reproductive stages, finding that Nitrososphaeria archaea are significantly associated with microbial composition shifts in species with previtellogenic oocytes.

This study examines dissolved organic matter (DOM) fluxes and fatty acid composition in New Zealand sponges, finding that some species release TDN and alter FDOM fluorophores, suggesting bacterial involvement in DOM transformation.

This study measures nitrification rates and nitrogen fluxes in a seagrass-sponge association, finding that the sponge supports the seagrass holobiont's nitrogen demand during growth and senescence.

This study identifies vertical transmission of cytotoxin-producing bacteria in marine sponges through bacteriocyte-like structures.

This study characterizes spirochete symbionts in latrunculid sponges, finding they are phylogenetically distinct and may provide functional benefits to their host.

This study examines nutrient fluxes, oxygen consumption, and fatty acid composition in deep-water sponges from New Zealand, identifying differences in nitrogen cycling and microbial communities among sponge clusters.

The paper analyzes mitochondrial DNA and 18S rRNA sequences from sponge species in an anchialine cave, revealing new species and genomic variation in the Demospongiae class.

The paper describes eleven new Haliclona species and redescribes Haliclona mollis from British Columbia, providing updated taxonomic placements.

This study examines transcriptomic responses of two sponge species to different microbial consortia, finding species-specific immune gene expression and a role for NLRs in microbial discrimination.

This study shows that losing a key microbial symbiont in sponges leads to body plan reorganization and transcriptomic changes, linking microbiome state to host development.

The paper introduces a hybrid-capture strategy for rRNA depletion in demosponge metatranscriptomes to better study host-microbe interactions.

The paper shows that bacterial symbionts in Amphimedon queenslandica larvae provide arginine for nitric oxide synthesis, enabling settlement and metamorphosis, and suggests a broader role for symbionts in metazoan development.

The paper compares metagenomic data of sponge-dwelling and pelagic bacteria to identify evolutionary trends in genome structure and function associated with sponge symbiosis.

This study investigates how light and biochemical cues interact to regulate larval settlement in the sponge Amphimedon queenslandica through transcriptomic analysis and settlement assays.

This paper uses mitochondrial genome data to test phylogenetic relationships within demosponges, particularly Heteroscleromorpha, and places Myceliospongia araneosa within a new clade.

This study identifies novel antimicrobial compounds from marine sponges through bioassay-guided fractionation and synthetic validation, showing activity against MRSA and other pathogens.
