1), in contrast to previous studies that have rarely reported this group as one of the dominant taxa in either active or extinct sulfide chimneys [16, 22, 76, 85, 93, 96]. Nat Microbiol. Further, napA/B genes were identified in every MAG assigned to Campylobacteria and 45% of Aquificae MAGs. Frontiers in Microbiology. 2006;314:1920–2. Hydrothermal vents generate CO2, which contributes to ocean acidification by forming carbonic acid in water. PubMed  For sulfur oxidation, most of the MAGs contained the genes encoding for the Sox system (69%) and sqr gene (63%) (Fig. The term succession refers to the gradual process of change that occurs in community structure over a period of time. Genes encoding for the enzymes catalyzing the subsequent steps of denitrification (nirS/K, norB/C, nosZ; Additional file 2: Table S7) were identified in 73% and 47% of the MAGs belonging to the Aquificae and Campylobacteria, respectively (Fig. Clean reads were mapped onto their assembled contigs respectively using bowtie2 (v2.2.8) with --very sensitive mode [41]. In contrast, the bacterial community of the inactive M-vent chimney was mainly composed of Gammaproteobacteria (22.9%) and Nitrospirae (17.3%), as well as Alpha- and Deltaproteobacteria (7.4% and 5.6%, respectively) (Fig. Thus, sulfide mineral utilization might be a key factor allowing these Nitrospirae to thrive in recently inactive sulfide chimneys, whose decay by oxidative weathering is largely proportional to the age of the inactive chimney, but is also controlled by their particular mineralogical and geological properties. Proceedings of the National Academy of Sciences. Oceanus. Generally, putative heterotrophic bacteria dominating the M-vent and other inactive chimneys, like Alpha-/Deltaproteobacteria, Chloroflexi, PVC, and FCB group, have also been widely identified in active chimneys, although generally with much lower relative abundances [16, 18, 85, 92,93,94]. Google Scholar. Table S7 Key genes of metabolic pathways for MAG annotation. This is well supported by the distinct differences between active and inactive sulfide chimneys extinct for > 1000 years, i.e., a community dominated by the Aquificae and Campylobacteria on one hand and an assemblage of the Gamma-/Delta-/Alphaproteobacteria and Bacteroidetes on the other hand [4, 33,34,35, 84].

Dahle H, Roalkvam I, Thorseth IH, Pedersen RB, Steen IH. Deep-sea hydrothermal vents are highly productive biodiversity hotspots in the deep ocean supported by chemosynthetic microorganisms. Miller CS, Baker BJ, Thomas BC, Singer SW, Banfield JF. The P values are based on Fisher’s exact test and corrected by Benjamini-Hochberg FDR. The completeness and contamination of MAGs were estimated via CheckM (v1.0.9) with lineage-specific markers genes [61]. New insight into microbial iron oxidation as revealed by the proteomic profile of an obligate iron-oxidizing chemolithoautotroph. 2b), with the majority of them assigned to Campylobacteria and Aquificae (Additional file 1: Figure S1a; 80% of norB and 75% of nosZ). Oceanography. 2006;8:114–25. As gigantic plates along the Earth’s crust move apart, crevices form in the ocean floor. We could further identify a unique “sulfide-mineral” Nitrospirae clade, making it a potential marker microorganism for young, recently extinct sulfide chimneys. The ISME Journal. Hydrothermal sulfide chimneys are typical vent structures, which are formed over short spatial and temporal scales by the precipitation of metal sulfides following the mixing of venting hydrothermal fluids with the surrounding cool, oxygenated seawater [10, 11]. ISME J. Water seeps in through the cracks and is heated by magma below the surface. In support of this hypothesis, Thiomicrospira sp. nov., a heavily flagellated archaeon that adheres to surfaces and forms cell-cell contacts. The other major microbial groups, such as Chloroflexi and the FCB group, have organotrophic potential, either using fermentation or respiration, which is supported by the considerable number of genes related to carbohydrate degradation and nitrate reduction (Fig. Since the … Hydrothermal mineral deposit, any concentration of metallic minerals formed by the precipitation of solids from hot mineral-laden water (hydrothermal solution).The solutions are thought to arise in most cases from the action of deeply circulating water heated by magma. Genome-resolved metagenomics was applied to an active and a recently extinct (~ 7 years) sulfide chimney from the 9–10° N hydrothermal vent field on the East Pacific Rise. The detailed taxonomic information and relative abundance of all reconstructed 16S rRNA genes are listed in Additional file 2: Table S3 and S4. Furthermore, 5 of all 9 Nitrospirae from the “sulfide mineral” clade (including the 2 most abundant recovered from the M-vent and the other 3 derived from recently extinct sulfide chimneys and SMS, respectively [37, 71]) encode the cyc2 gene (Additional file 2: Table S9). Image from NOAA. Energy landscapes shape microbial communities in hydrothermal systems on the Arctic Mid-Ocean Ridge. Figure S7 Phylogeny of 20 Gammaproteobacteria MAGs recovered from M- and L-vent chimney. Interestingly, compared with the active L-vent chimney, our results further revealed that the metabolic potential for sulfate reduction was more prevalent in the M-vent chimney, both at the gene and genomic level (Figs. In this study, most of the retrieved bacterial MAGs in the chimneys represent active replicating bacterial taxa as indicated by iRep values calculated from 52 and 91 high-quality bacterial MAGs from the L- and M-vent samples, respectively. Genes of the dissimilatory nitrate reduction to ammonia (DNRA) pathway were more abundant in the inactive M-vent chimney, with 74% of nitrite reductase large subunit (nirB) assigned to the Gammaproteobacteria (Additional file 1: Figure S1b). Hydrothermal Vent. For the denitrification pathway, the gene encoding for the beta subunit of the nitric oxide reductase (norB) and for the nitrous-oxide reductase (nosZ) were identified in significantly higher abundance in the active L-vent chimney compared to M-vent (Fig. Tivey MK. Li J, Zhou H, Fang J, Sun Y, Dasgupta S. Microbial distribution in different spatial positions within the walls of a black sulfide hydrothermal chimney. In the present study, these putative archaeal pioneers were also identified in the active L-vent chimney, including one Methanocaldococcus-like MAG in considerable abundance (3.8%; Fig. 4). Table S4 Taxonomic classification and relative abundance of full-length 16S rRNA genes recovered from M-vent sulfide chimney sample. This phenomenon, known as ecological succession, whereby there are changes in the composition or structure of a community, is well documented among plant and animal species. Water-rock reactions at high temperatures generated by subsurface magmatic heating transforms the seawater percolating into the ocean crust into hot, reduced, metal-rich hydrothermal fluids that vent from the seafloor. Sci Rep. 2016;6:34212. 4). The green-shaded branches are proposed as “Sulfide mineral” clade of Nitrospirae in this study. 2019;10:2296. Recovery of nearly 8,000 metagenome-assembled genomes substantially expands the tree of life. PubMed  mSystems 2020, 5:e00553-00519. Mar Ecol Prog Ser. The difference between primary and secondary succession is that primary succession occurs when a new deep sea vent emerges.This is a newly formed habitat where there has never been a community before. Figure S4 Distribution and quantity of top 50 RpS3 genes retrieved in the MAGs for two chimney samples. CH4 was also detected in both the L-vent and M-vent fluids at concentrations of 83 and 24 μM, respectively. Nguyen L-T, Schmidt HA, Von Haeseler A, Minh BQ. (b) (i) Explain why the water leaving hydrothermal vents is rich in minerals..... [2] (ii) Some minerals provide nutrients for marine organisms. Others live on the surface of rocks and animals wherever there is sufficient hydrogen sulfide to support chemosynthesis. A significantly higher abundance of genes encoding for adenylylsulfate reductase (aprA/B) and sulfite reductase (dsrA/B) were identified in the M-vent sample (Fig. 2015;91:1–11. Combining data obtained in the present study with those published previously (including studies from Guaymas Basin, East Pacific Rise 9°/13° N, Mid-Atlantic Ridge, Main Endeavor Field, Loki’s Castle vent field; as well as some in situ incubations and lab enrichments, details see Additional file 2: Table S11), we are proposing a conceptual model to understand the pattern of microbial succession: microbes in the sulfide chimney shift from a “fluid-shaped” community supported by electron donors in the fluid into a “mineral-shaped” one supported by solid-phase electron donors during the lifetime of a vent from initiation to extinction (Fig. The models of maturation and recently inactive stage are based on L-vent and M-vent in this study; data of initiation and long-time extinction stage are summarized from previous studies. Remarkably, the transition appears to occur within the first few years, after which the communities stay stable for thousands of years. ISME J. Assessing the influence of physical, geochemical and biological factors on anaerobic microbial primary productivity within hydrothermal vent chimneys. Langmead B, Salzberg SL. The coverage of recovered MAGs in the communities were estimated through a method based on the unique marker gene RpS3 [66], which were retrieved from these two chimney metagenomes by using hmmsearch (cutoff e value 1 × 10−10) in the Pfam 31.0 database [50]. Wang Y, Wegener G, Hou J, Wang F, Xiao X. Nature methods. After filtering the reduplicate contigs in multiple MAGs, we kept qualified MAGs with completeness ≥ 70% and contamination ≤ 9% based on the evaluation from CheckM with parameter lineage-specific. 2018;115:6756–61. Table S5 Completeness and contamination of 173 MAGs recovered from L- and M-vent chimney samples. Chloroflexi (5 MAGs), FCB group (7 MAGs), Gammaproteobacteria (4 MAGs), and Thermotogae (2 MAGs) accounted for 2%, 1.7%, 1.5%, and 1.1%, respectively. Differentially shaded tiles represent the completeness of displayed metabolic pathways, including none, partial, incomplete, and complete four levels. 2017;8:682. They contained not only the key genes encoding the complete sulfate reducing pathway (i.e., sat, aprA/B and dsrA/B), but also other essential marker genes like dsrD, the sulfite reductase-associated electron transfer complex (dsrM/K/J/O/P), and the electron transfer complex (QmoA/B/C) (Additional file 2: Table S8). Genome sequences of rare, uncultured bacteria obtained by differential coverage binning of multiple metagenomes. Authors of the new theory argue the environmental conditions in porous hydrothermal vents — where heated, mineral-laden seawater spews from cracks in the ocean crust — created a gradient … Appl Environ Microbiol. 2a), and more than 99% of them share high similarities with those from Campylobacteria and Aquificae (Additional file 1: Figure S1a). During the transition phase from a mature to an inactive sulfide chimney, a “fluid shaped” microbiome as described above is expected to shift to a “mineral-shaped” community (Fig. Contigs larger than 3 Kb from the two metagenomes were included to independently recover MAGs using MetaBAT2 (v2.12.1) and Maxbin (v2.2.1) with default parameters [59, 60]. Table S8 Sulfur metabolic pathways of Thermodesulfobacteria MAGs recovered. Geobiology. zonation, the successional patterns at hydrothermal vents have also been interpreted in terms of species' responses to changes in the character of hydrothermal vent flux.

J Microbiol. Genome analysis of Thermosulfurimonas dismutans, the first thermophilic sulfur-disproportionating bacterium of the phylum Thermodesulfobacteria. Despite the stark difference in temperature, the measured pH (25 °C) showed similar values of 4.8 and 5.2, respectively (Table 1). Parks DH, Beiko RG. Species colonizing new deep-sea hydrothermal vents along the East Pacific Rise show a distinct successional sequence: pioneer assemblages dominated by the vestimentiferan tubeworm Tevnia jerichonana being subsequently invaded by another vestimentiferan Riftia pachyptila, and eventually the mussel Bathymodiolus thermophilus. ISME J. PubMed Google Scholar. 2001;29:41–3. Based on the samples provided by U.S. Navy deep sea submersible Alvin, USC microbiologists discovered that life continues at hydrothermal vents even after they go dormant. Anantharaman K, Hausmann B, Jungbluth SP, Kantor RS, Lavy A, Warren LA, Rappe MS, Pester M, Loy A, Thomas BC, Banfield JF. This suggests that the Nitrospirae “sulfide-mineral” clade flourishes in the early stage of inactive sulfide chimneys, making them a potential marker microorganism for young, recently extinct sulfide chimneys. Next, the contigs with divergent genomic properties (GC content, tetranucleotide and sequencing depth) and incongruent taxonomic classifications were filtered from their belonged MAGs by using the “outliers” method of RefineM (v0.0.22) [63]. For instance, one can directly observe changes in the vegetation after a wildfire, but assessing animal community succession on hydrothermal vents is much more complicated. The Euryarchaeota MAGs recovered from M-vent are potential sulfate reducing archaea that are phylogenetically closely related to the Archaeoglobi lineage, which is supported by the retrieved 16S rRNA gene of the genus Geoglobus (Additional file 2: Table S4). Mol Biol Evol. 2018;20:862–77. Hydrogenases were predicted and classified based on hydrogenase classifier HydDB by using hmmsearch (e value cutoff < 1 × 10−10) [68]. Karine A, Magali Z, Nadine LB, Françoise L, Joël Q, Françoise G, Marie-Anne CB. All MAGs from the current study have been deposited in the NCBI GenBank under the project ID PRJNA557557. Table S10 Distribution and quantity of cytochrome c oxidase genes in 173 MAGs retrieved from M- and L-vent. Katoh K, Standley DM.

McCliment EA, Voglesonger KM, O'Day PA, Dunn EE, Holloway JR, Cary SC. This ... succession resulting from outside forces like tectonic activity, with each series of change called a seral stage. All 28 MAGs encode at least one sqr gene; 45% and 24% of them also encode complete or near complete Sox system (Fig. The authors declare that they have no competing interests. Qualified MAGs from two samples were phylogenetically assigned to appropriate taxonomic classifications based on a set of 37 concatenated universal single-copy protein sequences [63]. Genes encoding for the ATP-citrate lyase (aclA/B), the key enzyme of reductive tricarboxylic acid (rTCA) cycle, were identified in significantly higher abundance (P value < 0.05) in the active L-vent sample compared to M-vent (Fig. 2013;41:D590–6. 2014;30:1312–3.

Cookies policy. 2002;49:189–96. Figure S5 Maximum-likelihood phylogeny of coxL genes retrieved from L- and M-vent chimney. First of all, the Gammaproteobacteria are inferred to replace the Campylobacteria and Aquificae as the major primary producers during this process, instead fixing CO2 via CBB cycle and retrieving energy from mineral sulfides through multiple sulfur oxidation pathways (reverse DSR, Sox system and sqr). Here, the phylogeny of dsrA was used to distinguish between the two types [54]. 4). More importantly, two volcanic eruptions have been documented at this location in 1991 and 2006 with dramatic effects on the geology, chemistry, and biology [5,6,7,8,9], providing unparalleled opportunities to study the evolution of a hydrothermal vent system with dynamic volcanic activity as well as the corresponding microbial succession. Recent studies based on sets of genes that were likely to have been present within the first living cells trace the origin of life back to deep-sea hydrothermal vents. Sylvan JB, Toner BM, Edwards KJ. In short, hydrothermal fluid chemistry largely controls the primary microbial colonization in newly formed chimneys and shapes the microbial community within sulfide chimneys from the initial to the mature stages (Fig. Genome-resolved conceptual models of microbial succession within the sulfide chimney from initiation, maturation, recently inactive, and long-time extinction. Fast gapped-read alignment with Bowtie 2. 2009;47:235–47. FEMS Microbiol Ecol. In view of their requirement for H2, high temperature, and anoxic conditions, these hyperthermophilic archaea are likely present in the interior layers of the chimney, where these pioneers are expected to consistently contribute to the primary production throughout the lifetime of an active chimney [83, 84] (Fig. For the L-vent, the composition of the three IGT fluid samples showed significant variability in the concentration of Mg, indicative of variable degrees of inadvertent seawater entrainment during sample collection. The red branches represent the cyc2 genes recovered from the active L-vent chimney, while the blue ones are those from recently inactive M-vent chimney. Specific definition rules and types of cytochrome c oxidase genes could find in Table S7. 2002;3:198–206. SMS, FPW, and XX conducted fieldwork and sampling. Finn RD, Clements J, Eddy SR. HMMER web server: interactive sequence similarity searching. Environ Microbiol. The rTCA cycle is the sole carbon fixation pathway and was prevalently identified in the Aquificae and Campylobacteria MAGs (55% and 47%, respectively). Dahle H, Okland I, Thorseth IH, Pederesen RB, Steen IH. This analysis will help determine the process by which the second generation of microbes is capable of developing in the barren and dormant vents. In-situ incubation of iron-sulfur mineral reveals a diverse chemolithoautotrophic community and a new biogeochemical role for Thiomicrospira. 2012;9:357. Parks DH, Imelfort M, Skennerton CT, Hugenholtz P, Tyson GW. 3), in line with the polyphyletic feature of Nitrospirae reported before [62], highlighting the need to reclassify this phylum. Full-length 16S rRNA genes were reconstructed from clean reads of two metagenomes respectively by EMIRGE (v0.60.4) with default parameters and BLASTed against SILVA 123 SSURef_NR99 database with e values < 1 × 10−10 for taxonomic information [43, 44]. Sci Rep. 2018;8:10386. Most Campylobacteria identified at DSHV are uncultured, but information on available isolates and incubation studies suggests that they are either thermophiles or mesophiles with the capability of chemoautotrophy driven by oxidation of H2 and/or H2S dissolved in the vent fluids [14, 28,29,30,31,32]. 2007;35:1079–82. Barco RA, Hoffman CL, Ramirez GA, Toner BM, Edwards KJ, Sylvan JB. statement and to refine MAGs [62]. Dick GJ. The only exceptions besides the present study are two recently described inactive chimneys, one of them being a relatively young inactive chimney (0 ± 160 years) and the other one a much older inactive chimney (~ 2093 years) with Nitrospirae making up 83% and 38% of the community, respectively [37]. Detailed information is displayed in the Additional file 2: Table S3 and S4. Key genes for microbial carbon, nitrogen, and sulfur metabolisms were searched in the metagenomes of the two chimneys, and differences were revealed regarding gene inventories and the pathways utilized by these two communities (Fig. They directly feed off the solid iron and sulfur deposits that compose the vents, which are void of the nutrient-rich water their predecessors required to thrive. The aerobic CO dehydrogenase (CODH) shares a high similarity with other enzymes from molybdenum hydroxylase family [69].

Flores GE, Campbell JH, Kirshtein JD, Meneghin J, Podar M, Steinberg JI, Seewald JS, Tivey MK, Voytek MA, Yang ZK, Reysenbach AL. Based on the identification of genes encoding for napAB/narGH and the subsequent DNRA pathway in most of their MAGs, nitrate appears to be a potential alternative electron acceptor for Deltaproteobacteria. Reysenbach AL, Longnecker K, ., Kirshtein J, . Therefore, DSHV systems are considered a critical conduit for the exchange of energy and matter between the Earth’s interior and the ocean [3, 4]. MBio. Different color gradients in completeness, relative abundance (logged), genomic size, iRep value, and CAzyme represent their quantities among MAGs. A hydrothermal vent ecosystem forms after a volcanic eruption at the seafloor. An ecosystem starts with a handful of species colonizing, or settling down, in a barren environment. The red ID represented those Nitrospirae MAGs reconstructed from M-vent, the green ones represent those recovered from subseafloor massive sulfides [71] and the blue ones refer to those Nitrospirae retrieved from inactive sulfide chimneys [37]. The phylogenetic analysis of coxL from M-vent suggests that they are largely assigned to the putative FormII/BMS clade (Additional file 1: Figure S5). Forest ecosystems are able to gradually replenish themselves after being destroyed by massive forest fires. McNichol J, Sylva SP, Thomas F, Taylor CD, Sievert SM, Seewald JS. More sampling and further experiments are needed to elucidate the specific ecological significance of this clade during the succession from active to inactive chimneys, as well as the mechanisms involved in oxidation of sulfide minerals and the utilization of sulfate minerals as an electron acceptor. In fact, until recently, scientists believed that all forms of life in this ecosystem disappeared when thermal currents were absent. YZW contributed to the data analysis and conceived the study. Int J Syst Evol Microbiol. Using hydrothermal vents, explain the difference between primary and secondary succession. 4) [81, 82]. https://doi.org/10.1186/s40168-020-00851-8, DOI: https://doi.org/10.1186/s40168-020-00851-8. Bacteria belonging to the phylum Aquificae had the second highest relative abundance (14.7%), followed by members of the phylum Chlorobi (4.7%), Thermodesulfobacteria (3.2%), and Deinococcus-Thermus (2.4%) (Fig. Bellack A, Huber H, Rachel R, Wanner G, Wirth R. Methanocaldococcus villosus sp. Bioinformatics. Nat Rev Microbiol. 3), while the other 2 Nitrospirae MAGs were part of a separate clade (Additional file 1: Figure S6). In addition, the majority of Aquificae and Campylobacteria MAGs encode hydrogenase groups 1 and 2 for hydrogen uptake. Distribution, diversity and ecology of aerobic CO-oxidizing bacteria. Our findings reveal that ecological succession occurs on hydrothermal sulfides after active venting ceases and also imply a potential shift in microbial metabolic guilds. 2008;10:874–84. SC-1, a FeOB recently isolated from an in situ incubation with pyrrhotite, has been shown to grow autotrophically with iron oxides and sulfur intermediates [30, 90]. On the other hand, soxA/C/Y/Z were found highly enriched in the active L-vent chimney, most of which (95%) were assigned to the Aquificae and Campylobacteria (Additional file 1: Figure S1a). Front Microbiol. Support for internal nodes was constructed from 1000 bootstrap replicates, black dots represent those nodes with bootstrap value > 75%, which is direct proportional to their diameter. While our data support this hypothesis, the finding of cyc2 genes in the “sulfide-mineral” clade further suggests that the oxidation of Fe2+ might also play an important role for these unique Nitrospirae enabling them to thrive in young inactive chimneys. nov.). In contrast, fluids exiting M-vent contained 0.00042 mM sulfide and H2 was below the detection limit of 2 μM. The 4 Nitrospirae MAGs recovered belonging to the “sulfide-mineral” clade encode essential genes of DSR, WL pathway, nitrite reduction and nitrogen fixation, same as the other 5 MAGs in this clade (Fig. Proc Natl Acad Sci U S A. Specific key genes and their accession in different databases are listed in Additional file 2: Table S7. A team led by USC microbiologist Katrina Edwards found that the microbes that thrive on hot fluid methane and sulfur spewed by active hydrothermal vents are … When the temperature achieved a stable reading, the inlet valve of the sampler was opened for 2 min and then closed to maintain in situ pressure during recovery. The distribution and succession of microbial communities along the dispersion path of hydrothermal plumes has not been well investigated. 1979;277:523.

Meier et al [37] propose that mineral sulfate, like anhydrite and/or barite, serves as a potential electron acceptor for Nitrospirae inhabiting young inactive chimneys [37]. Nat Commun. Hydrothermal vents form at locations where seawater meets magma. In addition, 50% of the MAGs also contain the gene encoding for the reverse DSR as evidenced by the phylogenetic assignment of the dsrA gene (Additional file 1: Figure S2), indicating the potential for the oxidative DSR pathway for sulfur oxidation. Zhang X, Morono Y, Inagaki F, Wang F. A modified SDS-based DNA extraction method for high quality environmental DNA from seafloor environments. Figure S2 Maximum-likelihood phylogeny of dsrA genes retrieved from L-vent and M-vent chimney. The reference genome dataset was downloaded from NCBI genome database in February 2018, including all available archaeal genomes and selected bacterial genomes with at least 10 from each order. Here, we present the first reported metagenome from an inactive sulfide chimney that went extinct at a precisely known time after a volcanic eruption in 2006, making it significant to understand the microbial succession taking place during the initial transition from an active chimney to an inactive one. The new microbes may also differ from their predecessors in their ability to thrive in highly acidic environments. Here, we determined the iRep value for those bacterial MAGs with ≤ 175 scaffolds per Mb by using the official script (https://github.com/christophertbrown/iRep).
