Rickettsiales are an enigmatic clade of strictly host-associated bacteria, which some very common in aquatic habitats. Despite a wealth sequencing-based observations, the hosts for many these marine still unknown. The first molecular data from two closely related placozoan species points to as abundant symbionts simple and early-branching animals. Given electron microscopy observations intracellular Rickettsia-like-organisms all placozoans examined, we systematically characterized...
Abstract. Increased human impacts on Earth systems are radically altering biogeochemical cycles. While long-term environmental observatories and System Models (ESMs) provide valuable insights into the mechanisms of nutrient dynamics, their performance is limited at fine spatial scales controlled by functional diversity plant microbial communities. This gap in our understanding concerning roles plant-microbial interactions decomposition dynamics extends across many global ecosystems. Recent...
Abstract Sulfate-reducing bacteria inhabit marine and terrestrial environments, forming syntrophic associations with other bacteria, archaea eukaryotes. A notable example is the symbiosis between sulfate-reducing (SRB) gutless oligochaete worms found in sediments worldwide. These endosymbionts participate a sulfur exchange primary endosymbiont of oligochaetes, sulfur-oxidizing bacterium, thus providing otherwise inaccessible metabolic capabilities to animal host. Here, we used combination...
Abstract Many animals are obligately associated with microbial symbionts that provide essential services such as nutrition or protection against predators. It is assumed in obligate associations fidelity between the host and its must be high to ensure evolutionary success of symbiosis. We show here this not case marine oligochaete worms, despite fact they so dependent on their bacterial for waste recycling have lost digestive excretory systems. Our metagenomic analyses 64 gutless species...
Saltmarshes are hotspots of organosulfur compound cycling due to production dimethylsulfoniopropionate (DMSP) by benthic microorganisms, macroalgae, and saltmarsh vegetation. Degradation DMSP is a source dimethylsulfide (DMS), an important precursor for formation secondary organic aerosol. Microorganisms degrading DMS play role in controlling the amount available emission into atmosphere. Previous work has implicated sediment microbial populations as major sink DMS. Here, we show that...
