Abstract Marine Porifera host diverse microbial communities, which influence metabolism and fitness. However, functional relationships between sponge microbiomes metabolic signatures are poorly understood. We integrate microbiome characterization, metabolomics predicted functions of four coexisting Mediterranean sponges – Petrosia ficiformis , Chondrosia reniformis Crambe crambe Chondrilla nucula . Microscopy observations reveal anatomical differences in densities. Microbiomes exhibit strong species-specific trends. C. shares many rare amplicon sequence variants (ASV) with the surrounding seawater. This suggests important inputs diversity acquired by selective horizontal acquisition. Phylum Cyanobacteria is mainly represented According to putative functions, P. functionally heterotrophic, while autotrophic. The species display distinct profiles at single compound level. molecular class level they share a “core metabolome”. Concurrently, we find global microbiome-metabolome association when considering all species. Within each still, sets microbe/metabolites identified driving multi-omics congruence. Our findings suggest that players may promote niche diversification, but also, analogous phenotypic patterns “symbiont evolutionary convergence” assemblages where holobionts co-exist same area.

Dispersal is an important life history trait that plays a key role in the demography and evolution of species. We employed combined approach DNA sequencing transmission electron microscopy to examine changes microbiome during ontogeny dispersal coral-excavating sponge Thoosa mismalolli. The results show can acquired their associated bacteria via both vertical (VT) horizontal (HT). Adult sponges, brooding larvae, early free-swimming larvae harbor similar high-diversity microbial assemblage, dominated by Proteobacteria Chloroflexi, which change throughout larval phase. Larvae collected offshore showed reorganization with significant reduction dominance inherited (Proteobacteria Chloroflexi), enrichment environmentally derived taxa (Bacteroidetes, Tenericutes, Firmicutes). TEM confirmed substantial cell structure composition, attributed symbionts' massive phagocytosis. This research provides information on dynamics through sheds possible capacity larvae.

ABSTRACT Marine invertebrates mainly reproduce by energy-poor eggs that develop into feeding larvae or energy-rich non-feeding larvae. Evolutionary transitions between these developmental modes have been studied in detail, yet the evolutionary factor(s) responsible for switches remains elusive. Here, we use theoretical models to support premise microbes with capacity manipulate host reproduction may be one possible factor. Our model predicts microbial manipulators could create a sperm-limited environment selects larger shifting host’s sex ratio toward female dominance and, as result, drive an transition mode marine invertebrates. The loss of manipulator then recover ancestral egg size and mode. We also suggest more than dozen genera from throughout world’s oceans fit framework microbe-induced predominant modes. anticipate yet-to-be-appreciated influence on evolution find it paramount understand whether occur without well underlying mechanisms manipulations are convergent terrestrial systems.

Metaorganism research contributes substantially to our understanding of the interaction between microbes and their hosts, as well co-evolution. Most is currently focused on bacterial community, while archaea often remain at sidelines metaorganism-related research. Here, we describe archaeome a total eleven classical emerging multicellular model organisms across phylogenetic tree life. To determine microbial community composition each host, utilized combination bacteria-specific 16S rRNA gene amplicons. Members two prokaryotic domains were described regarding composition, diversity, richness in host. Moreover, association with specific hosts possible partners archaeal communities determined for marine models. Our data show that predominantly consists Nitrosopumilaceae Nanoarchaeota , which represent keystone taxa among porifera. The presence an terrestrial varies substantially. With respect abundant taxa, they harbor higher proportion methanoarchaea over aquatic environment. We find much less diverse than its counterpart. Archaeal amplicon sequence variants are usually host-specific, suggesting adaptation through co-evolution While was significant difference diversity these groups could not be observed dataset. large unclassifiable highlighting need improved cultivation efforts expanded databases.

Sponge-associated bacteria play important roles in the physiology of their host, whose recruitment processes are crucial to maintain symbiotic associations. However, acquisition bacterial communities within freshwater sponges is still under explored. Spongilla lacustris a model sponge widely distributed European rivers and lakes, producing dormant cysts (named gemmules) for asexual reproduction, before winter. Through an vitro experiment, this study aims describe dynamics transmission modes following hatching these gemmules.

Abstract Background: Sponges-associated bacteria play important roles in the physiology of their host, whose recruitment processes are crucial to maintain symbiotic associations. However, acquisition bacterial communities within freshwater sponges is still unexplored. Spongilla lacustris a model sponge widely distributed European rivers and lakes, producing dormant cysts (named gemmules) for asexual reproduction, before winter. Through an in vitroexperiment, this study aims describe dynamics transmission modes following hatching these gemmules. Results: An overall change β-diversity was observed through ontology new juvenile sponges. These temporal differences were potentially linked first osculum development canal system, then, increasing colonization Chlorella-like photosymbionts. Gemmules with sterilized surface found have more dispersed less diverse microbiome, revealing importance gemmule epibacteria whole holobiont stability. suggested be vertically transmitted from maternal tissues surface. Vertical incorporation inside gemmule, also as dominant mode, especially nitrogen fixers Terasakiellaceae. Finally, we showed that almost no ASVs shared between free-living community juveniles, suggesting horizontal unlikely happen during stages development. filtered probably used source nutrients, allowing enrichment copiotrophic already present its microbiome.
