ABSTRACT Complex microbiomes reside in marine sponges and consist of diverse microbial taxa, including functional guilds that may contribute to host metabolism coastal nutrient cycles. Our understanding these symbiotic systems is based primarily on static accounts sponge microbiota, while their temporal dynamics across seasonal cycles remain largely unknown. Here, we investigated variation bacterial symbionts three sympatric ( Ircinia spp.) over 1.5 years the northwestern (NW) Mediterranean...
Almost all animals and plants are inhabited by diverse communities of microorganisms, the microbiota, thereby forming an integrated entity, metaorganism. Natural selection should favor hosts that shape community composition these microbes to promote a beneficial host-microbe symbiosis. Indeed, animal often pose selective environments, which only subset environmentally available able colonize. How assemble after colonization form complex microbiota is less clear. Neutral models based on...
Abstract In the deep ocean symbioses between microbes and invertebrates are emerging as key drivers of ecosystem health services. We present a large-scale analysis microbial diversity in deep-sea sponges (Porifera) from scales sponge individuals to basins, covering 52 locations, 1077 host translating into 169 species (including understudied glass sponges), 469 reference samples, collected anew during 21 ship-based expeditions. demonstrate impacts abundance status, geographic distance,...
Dispersal limitation and environmental selection are the main processes shaping free-living microbial communities, but host-related factors may also play a major role in structuring symbiotic communities. Here, we aimed to determine effects of isolation-by-distance host species on spatial structure sponge-associated bacterial communities using as model abundant demosponge genus Ircinia. We targeted three co-occurring Ircinia used terminal restriction fragment length polymorphism (T-RFLP)...
The innate immune system helps animals to navigate the microbial world. response microbes relies on specific recognition of microbial-associated molecular patterns (MAMPs) by receptors. Sponges (phylum Porifera), as early-diverging animals, provide insights into conserved mechanisms for animal-microbe crosstalk. However, experimental data is limited. We adopted an approach followed RNA-Seq and differential gene expression analysis in order characterise sponge response. Two Mediterranean...
Sporadic mass mortality events of Mediterranean sponges following periods anomalously high temperatures or longer than usual stratification the seawater column (i.e. low food availability) suggest that these animals are sensitive to environmental stresses. The Ircinia fasciculata and I. oros harbor distinct, species-specific bacterial communities highly stable over time space but little is known about how anomalous conditions affect structure resident communities. Here, we monitored in...
Recent episodes of mass mortalities in the Mediterranean Sea have been reported for closely related marine sponges Ircinia fasciculata and variabilis that live sympatry. In this context, assessment genetic diversity, bottlenecks connectivity these has become urgent order to evaluate potential effects on their latitudinal range. Our study aims establish (1) structure, signs across populations I. (2) hybridization levels between variabilis. To accomplish first objective, 194 individuals from...
Bacteriophages (phages) are ubiquitous elements in nature, but their ecology and role animals remains little understood. Sponges represent the oldest known extant animal-microbe symbiosis associated with dense diverse microbial consortia. Here we investigate tripartite interaction between phages, bacterial symbionts, sponge host. We combined imaging bioinformatics to tackle important questions on who phage hosts what replication mode spatial distribution within animal is. This approach led...
Archaea associated with marine sponges are active and influence the nitrogen metabolism of sponges. However, we know little about their occurrence, specificity, persistence. We aimed to elucidate relative importance host specificity biogeographic background in shaping symbiotic archaeal communities. investigated these communities sympatric from Mediterranean (Ircinia fasciculata Ircinia oros, sampled summer winter) Caribbean strobilina Mycale laxissima). PCR cloning sequencing 16S rRNA amoA...
The animal immune system mediates host-microbe interactions from the host perspective. Pattern recognition receptors (PRRs) and downstream signaling cascades they induce are a central part of innate immunity. These molecular mechanisms still not fully understood, particularly in terms baseline immunity vs induced specific responses regulated upon microbial signals. Early-divergent phyla like sponges (Porifera) can help to identify evolutionarily conserved signaling. We characterized both...
Abstract Upon injury, the homeostatic balance that ensures tissue function is disrupted. Wound-induced signaling triggers recovery of integrity and offers a context to understand molecular mechanisms for restoring homeostasis upon disturbances. Marine sessile animals are particularly vulnerable chronic wounds caused by grazers can compromise prey’s health. Yet, in comparison other stressors like warming or acidification, we know little on how marine respond grazing. sponges (Phylum Porifera)...
Marine sponges are known for their complex and stable microbiomes. However, the lack of a gnotobiotic sponge-model experimental methods to manipulate both host microbial symbionts currently limit our mechanistic understanding sponge-microbial symbioses. We have used North Atlantic sponge species Halichondria panicea evaluate use antibiotics generate sponges. further asked whether microbiome can be reestablished via recolonization with natural microbiome. Experiments were performed in marine...
Ctenophora are basal marine metazoans, the sister group of all other animals. Mnemiopsis leidyi is one most successful invasive species worldwide with intense ecological and evolutionary research interest. Here, we generated a chromosome-level genome assembly M. focus on its immune gene repertoire. The was 247.97 Mb, N50 16.84 84.7% completeness. Its karyotype 13 chromosomes. In this that two ctenophores, Bolinopsis microptera Hormiphora californensis, detected high number protein domains...
Abstract The study of oral regeneration in the sea anemone Exaiptasia diaphana (commonly called Aiptasia) - a prominent model for coral-algal symbiosis offers unique opportunity to investigate role symbionts regeneration. Algal have potential affect healing and by supplementing host nutrition and/or modulating immune responses. Here we revisited descriptions Aiptasia from 1970s with modern imaging techniques. Upon amputation, anemones progressed through six distinct repeatable stages wound...
