Comparing Deep-Sea Sponges of the Species Geodia Barretti from Different Locations in the North Atlantic
Comparing deep-sea sponges of the species Geodia barretti from different locations in the North Atlantic Isabel Ordaz Németh The study of genetic and geographic structures of populations for poorly studied species is not exactly straightforward. It is difficult to accurately compare populations of a species from which no genetic data is available. So, is there a way of comparing populations of such as species? There is one possibility, which is by using genetic markers called “Exon-Primed Intron- Crossing” (EPIC) markers. These markers, which are first designed for well-studied species, find a specific piece of DNA that all individuals of a species have. So, by using the markers we can, for example, take the same DNA fragment from several individuals that come from different locations. Then we translate the DNA fragments of these individuals and look at how different they are. This can give us a lot of information about the relationships within and between the populations of a species, as well as its history. Since a lot of genetic information is conserved across different species, we can test these markers on a species that we barely know, and the probability of finding a corresponding DNA fragment can still be quite high. EPIC markers could be very useful for different studies but they haven’t been extensively used since they are relatively new. In this project, the markers were tested on samples of the deep-sea sponge Geodia barretti. The sponges that were used came from different locations; from the Mediterranean Sea, to the coast of Norway, and all the way to the other side of the Atlantic, by the Eastern coast of Canada. -

Abstract : Although most of the key components of the transcription apparatus, and in particular, RNA polymerase (RNAP) subunits, are conserved between archaea and eukaryotes, no archaeal homologs of the small RPB8 subunit of eukaryotic RNAP have been detected. We report that orthologs of RPB8 are encoded in all sequenced genomes of hyperthermophilic Crenarchaeota and a recently sequenced "korarchaeal" genome, but not in Euryarchaeota or the mesophilic crenarchaeon Cenarchaeum symbiosum. These findings suggest that all 12 core subunits of eukaryotic RNAPs were already present in the last common ancestor of the extant archaea. -

Novel Insights Into the Thaumarchaeota in the Deepest Oceans: Their Metabolism and Potential Adaptation Mechanisms
Zhong et al. Microbiome (2020) 8:78 https://doi.org/10.1186/s40168-020-00849-2 RESEARCH Open Access Novel insights into the Thaumarchaeota in the deepest oceans: their metabolism and potential adaptation mechanisms Haohui Zhong1,2, Laura Lehtovirta-Morley3, Jiwen Liu1,2, Yanfen Zheng1, Heyu Lin1, Delei Song1, Jonathan D. Todd3, Jiwei Tian4 and Xiao-Hua Zhang1,2,5* Abstract Background: Marine Group I (MGI) Thaumarchaeota, which play key roles in the global biogeochemical cycling of nitrogen and carbon (ammonia oxidizers), thrive in the aphotic deep sea with massive populations. Recent studies have revealed that MGI Thaumarchaeota were present in the deepest part of oceans—the hadal zone (depth > 6000 m, consisting almost entirely of trenches), with the predominant phylotype being distinct from that in the “shallower” deep sea. However, little is known about the metabolism and distribution of these ammonia oxidizers in the hadal water. Results: In this study, metagenomic data were obtained from 0–10,500 m deep seawater samples from the Mariana Trench. The distribution patterns of Thaumarchaeota derived from metagenomics and 16S rRNA gene sequencing were in line with that reported in previous studies: abundance of Thaumarchaeota peaked in bathypelagic zone (depth 1000–4000 m) and the predominant clade shifted in the hadal zone. Several metagenome-assembled thaumarchaeotal genomes were recovered, including a near-complete one representing the dominant hadal phylotype of MGI. Using comparative genomics, we predict that unexpected genes involved in bioenergetics, including two distinct ATP synthase genes (predicted to be coupled with H+ and Na+ respectively), and genes horizontally transferred from other extremophiles, such as those encoding putative di-myo-inositol-phosphate (DIP) synthases, might significantly contribute to the success of this hadal clade under the extreme condition. -

This article is published with open access Abstract Ammonia-oxidizing archaea (AOA) are among the most abundant and ubiquitous microorganisms in the ocean, exerting primary control on nitrification and nitrogen oxides emission. Although united by a common physiology of 1234567890();,: 1234567890();,: chemoautotrophic growth on ammonia, a corresponding high genomic and habitat variability suggests tremendous adaptive capacity. Here, we compared 44 diverse AOA genomes, 37 from species cultivated from samples collected across diverse geographic locations and seven assembled from metagenomic sequences from the mesopelagic to hadopelagic zones of the deep ocean. Comparative analysis identified seven major marine AOA genotypic groups having gene content correlated with their distinctive biogeographies. -

The possibility of using Exon-Primed Intron-Crossing (EPIC) markers in the deep-sea sponge species Geodia barretti is explored in this project. The sponge specimens that were tested came from different localities of the North Atlantic. Results: An EPIC marker was found to show genetic variability among the sponge specimens. Based on the resulting DNA sequences of the sponges, a phylogenetic analysis was made, which showed the genetic connectivity among them. Conclusions: EPIC markers are effective genetic markers variable enough to apply them to poorly studied marine species such as G. -
Implications for Dredging Management
www.nature.com/scientificreports OPEN Effects of light attenuation on the sponge holobiont- implications for dredging management Received: 08 June 2016 Mari-Carmen Pineda1,2, Brian Strehlow1,2,3, Alan Duckworth1,2, Jason Doyle1, Ross Jones1,2 & Accepted: 17 November 2016 Nicole S. Webster1,2 Published: 13 December 2016 Dredging and natural sediment resuspension events can cause high levels of turbidity, reducing the amount of light available for photosynthetic benthic biota. To determine how marine sponges respond to light attenuation, five species were experimentally exposed to a range of light treatments. Tolerance thresholds and capacity for recovery varied markedly amongst species. Whilst light attenuation had no effect on the heterotrophic speciesStylissa flabelliformis and Ianthella basta, the phototrophic species Cliona orientalis and Carteriospongia foliascens discoloured (bleached) over a 28 day exposure period to very low light (<0.8 mol photons m−2 d−1). In darkness, both species discoloured within a few days, concomitant with reduced fluorescence yields, chlorophyll concentrations and shifts in their associated microbiomes. The phototrophic species Cymbastela coralliophila was less impacted by light reduction. C. orientalis and C. coralliophila exhibited full recovery under normal light conditions, whilst C. foliascens did not recover and showed high levels of mortality. The light treatments used in the study are directly relevant to conditions that can occur in situ during dredging projects, indicating that light attenuation poses a risk to photosynthetic marine sponges. Examining benthic light levels over temporal scales would enable dredging proponents to be aware of conditions that could impact on sponge physiology. Sponges are filter-feeding organisms with important ecosystem roles including habitat provision, seawater filtra- tion, primary production and binding and/or erosion of the carbonate reef structure1.
