seagrass zostera phylum

It seemed that Woesearchaeota presented much higher proportions in the Z. marina seagrass system than in mangroves. These strains were isolated from sediment surrounding the roots of the seagrass, Zostera marina , collected near the UC, Davis Bodega Marine Laboratory (Bodega Bay, California). Overall, the most abundant phylum was Woesearchaeota (, ; ), followed by Bathyarchaeota (), Thaumarchaeota (), and Euryarchaeota (). can recover from normal grazing (Naken & Reise, 2000; Davison & Hughes, 1998). Besides, Woesearchaeota was also usually found to be the most abundant in anaerobic nitrogen-removing wastewater treatment sludge [60]. FEMS Microbiol. Cifuentes et al. Supplementary Figure S1: The phylogenetic maximum-likelihood (ML) tree was constructed for all Woesearchaeota 16S rRNA gene sequences obtained in the study with bacterial 16S rRNA gene sequences as the outgroup. The data used to support the findings of this study are included within the article and the supplementary information files. The pool of sediment organic matter in seagrass meadows is composed of deposited planktonic or epiphytic algae and seagrass debris as well as root-leaching dissolved organic carbon. Maximum likelihood (ML) trees were built in the “FastTree” program with the GTRGAMMAI model, and a bootstrap analysis of 1,000 replications was applied in all phylogenetic analyses. Taxonomy was assigned at a sequence similarity of 0.97. De Mesel, M.

Within Woesearchaeota, the sequences were clustered into 26 subclades according to the classification proposed by Liu et al. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. The identified Thaumarchaeota were mainly composed of Group C3, Marine Group I (formerly referred to as Marine Group 1.1a), and Soil Crenarchaeotic Group (formerly Marine Group 1.1b) in this study (Table S2). How this seagrass colonization-induced spatial heterogeneity affects archaeal community structure and abundance remains unclear. Copyright © 2019 Pengfei Zheng et al. For example, evolutionists assume that flowering plants (phylum Anthophyta) evolved from non-flowering plants perhaps 160 million years ago. Our studies highlight the niche preferences of archaeal individuals, especially the subclades of the abundant Woesearchaeota and Bathyarchaeota phyla. Here we used culture-independent sequencing of the ribosomal internal transcribed spacer (ITS) region to characterize the taxonomic diversity of fungi associated with the seagrass, Zostera marina. qPCR was performed using the primers A931F (5-AGGAATTGGCGGGGGAGCA-3) and M1100R (5-BGGGTCTCGCTCGTTRCC-3) [26, 27], with the following program: 7 min of initial denaturation at 95°C, followed by 40 cycles of 95°C for 30 s, 64°C for 30 s, and 72°C for 30 s. The data were retrieved at 72°C, and all of the reactions were completed with a melting curve from 60°C to 95°C with increases of 0.5°C each cycle. Lever, K. U. Hinrichs, and F.

YOU can too by helping us plant seagrass! Here we used culture-independent sequencing of the ribosomal internal transcribed spacer (ITS) region to characterize the taxonomic diversity of fungi associated with the seagrass, Zostera marina. Seagrass beds perform important ecosystem services and can store carbon over very long timescales in their above and below ground tissues and in surrounding sediments (i.e. Seagrass wasting disease in the 1930s resulted in mass decline of seagrass Zostera marina in the Northern Atlantic Ocean. In fact, compared with 931F/M1100R, the primer set 344F/519R has slightly different coverages for some major archaeal groups (e.g., Bathyarchaeota, Woesearchaeota, Thaumarchaeota, and Euryarchaeota), but contrastingly different coverages for Korarchaeota, Hadesarchaeaeota, and Asgardaeota, as shown by the results of TestPrime 1.0 (https://www.arb-silva.de/search/testprime/) [24]. XDA23050303), the China Natural Science Foundation (No. The remaining taxa, such as Miscellaneous Euryarchaeotic Group (MEG), WSA2, Diapherotrites, Altiarchaeales, and AK8, were rare (<1%) across all samples (Figure 1(a)). Different bacterial communities in the rhizoplane and bulk sediment of the seagrass Zostera marina. It is an aquatic plant native to marine environments on the coastlines of mostly northern sections of North America and Eurasia. Based on the evidence from enrichment experiments, Bathy-8 can grow using the refractory aromatic polymer lignin as an energy source, during which its relative proportion doubled compared to the initial stage with lignin addition [48]. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. 500 spp. Within Bathyarchaeota, the most abundant subclade, Bathy-6, was significantly promoted in the vegetated sediments (Figure 1(c)). Interestingly, the proportions of Woesearchaeota obtained in this study were comparable with those in the adjacent Bohai Sea and Yellow Sea surface sediments (30-60%) and much higher than those in the distant East China Sea (approximately 10%) [32], suggesting that the distribution of Woesearchaeota might also be driven by geographic distance.

Seagrasses are globally distributed marine flowering plants that are foundation species in coastal ecosystems. Seagrass beds provide shelter for all sorts of other life, increasing biodiversity, so it’s critically important that we protect them.

Seagrass wasting disease in the 1930s resulted in mass decline of seagrass Zostera marina in the Northern Atlantic Ocean. Z. marinaleaf blades are characteristically flat and wide (2-12 mm) and can reach up to 3 meters in length (Mondragon and Mondragon, 2003) although morphology is variable and depends on environmental factors such as substrate type (Short, 1983), depth (Lee et al., 2000), temperature (Moore et al., 1996), and light and nutrient availability (Short, 1983). The pairwise differences were examined using t-tests (n = 3), and significant differences (P < 0.05) were highlighted in bold. We then used PCR with a primer targeting unique regions of the ITS2 region of this ASV and an existing primer for the fungal 28S rRNA gene to amplify part of the 28S rRNA gene region and link it to this ASV. Profile lexID: 12569 AphiaID: 593702 Scientific: Zostera nigricaulis German: Seegras English: Seagrass Category: Seaweeds Family tree: Plantae (Kingdom) > Tracheophyta (Phylum) > Magnoliopsida (Class) > Alismatales (Order) > Zosteraceae (Family) > Zostera (Genus) > nigricaulis (Species) Initial determination: In terrestrial systems, fungi can have beneficial and detrimental effects on plant fitness. Can be confused with other species in the genus Zostera.Z. In mangrove wetlands, pH is also an important force shaping the Bathyarchaeotal community structure [16]. The genus Zostera contains 15 species. Zostera marina. The analysis of the genomics of Woesearchaeota indicated that this archaea group harbored nitrogen removal genes such as nirK and nosZ [12], suggesting that Woesearchaeota might participate in nitrogen removal processes and contribute to lower the DIN level in the vegetated sediments. However, little is known about archaeal diversity and spatial distributions in seagrass ecosystems. The relative proportion of Bathyarchaeota was almost twice as high in vegetated sediments as in unvegetated sediments (Figure 1(a)); in particular, the subclades Bathy-6 and Bathy-18 were significantly enriched in vegetated sediments (, Figure 1(c)). conclusions are: (1) Annelida and Polychaeta are non-monophyletic, even when Pogonophora; (2) Articulata, as traditionally circumscribed for Annelida and. Seagrass roots release oxygen to sediments, which results in less reducing and sulfide-depleted conditions in seagrass-colonized sediments [6, 45, 46], together with rich seagrass-derived organic matters, and Bathy-6 was well fueled in the sediments. Recent studies found that Woesearchaeota was strongly stimulated in Taihu Lake surface sediments during a cyanobacterial bloom [30] and that Woesearchaeota might be involved in the anaerobic carbon cycling [29]. … Boon, “Retention of lignin in seagrasses: angiosperms that returned to the sea,”, D.

Here, we present the draft genome sequences of Pseudoalteromonas porphyrae UCD-SED9 and UCD-SED14 (phylum Proteobacteria). reported that the abundance of Bathyarchaeota in the mangrove sediments was significantly higher than that in the mud-flat sediments, and it showed positive correlation with sediment TOC content [16]. It is a monoecious, predominantly annual, glabrous herb. Epiphytic bacteria phylum/class. In addition, latitude could be another factor governing the distribution of Woesearchaeota in the Z. marina seagrass meadow and mangroves. Although many studies have focused on seagrass ecology, only a limited number have investigated their associated fungi. Though the whole Woesearchaeota phylum showed similar relative proportions in seagrass-colonized and bare sediments (Figure 1(a)), its subclades Woese-3 and Woese-21 tended to be more abundant in seagrass-colonized sediments (Figure 1(b)). This … Found in temperate and subtropical climates around the world, these species grow in intertidal and subtidal portions of coastal areas. Supplementary Table S2: Comparison of the relative proportions and 16S rRNA gene copy numbers of archaeal lineages based on SILVA (v. 128) between the vegetated and unvegetated sediments. Woese-2 (), Woese-9 (), and Woese-11 () were the major subclades among all samples (Figure 1(b), Table S2). Here we use environmental DNA (eDNA) amplicons to analyze a broad cross-section of taxa from ecological communities in and immediately surrounding eelgrass (Zostera marina). Woese-3 prefers oxic environments [12], which was selectively enriched in vegetated sediments, possibly due to increased oxygen around the plant rhizosphere [6]. Zostera japonica is found in broadly sheltered bays on sandy or muddy coasts from 1-3 m depth along cool to subtropical sea coasts of eastern Asia (Miki 1933).. … Eelgrass The temperate seagrass Zostera marina which is the dominant seagrass from Canada to the Carolinas, northern latitudes on the eastern Atlantic coast of Europe and the Pacific ocean. We sampled from two Z. marina beds in Bodega Bay over three time points to investigate fungal diversity within and between plants. This is a small seagrass. Comparison of the archaeal community composition between vegetated and unvegetated sediments: (a) at the phylum level (MHVG, Marine Hydrothermal Vent Group; AAG, Ancient Archaeal Group; Others, archaeal phyla with relative. It is assumed that the source and quality of sediment organic matter regulate the relative abundance of Woesearchaeota.

It's fairly easy to explain the evolution of plants, animals, or people if one presupposes that Darwinian evolution is a scientific fact. Review articles are excluded from this waiver policy. Similarly, the copy number of Bathyarchaeota ( copies g-1 sediment) was approximately 4 times that in the unvegetated samples (), which was apparently due to the higher abundance of four of its subclades, Bathy-6, Bathy-8, Bathy-15, and Bathy-18 () (Figures 4(a), 4(c)). According to sequence origins [12], Woese-2 and Woese-9 were only detected in anoxic environments, and Woese-2 was only observed in saline or hypersaline environments, suggesting that anoxic and saline conditions in the seagrass meadow sediments could contribute to the evolutionary diversity of Woesearchaeota. This was in line with the distribution of Bathyarchaeota subclades in mangrove sediments [16, 47]. Common names for this species are eelgrass, seagrass, and seawrack. This work was supported by a grant from the Strategic Priority Research Program of the Chinese Academy of Sciences (No. Seagrass beds provide a variety of ecosystem services, both within and outside the bounds of the habitat itself. We found that Woesearchaeota dominated (approximately 42%) in archaeal communities of the seagrass system, followed by Bathyarchaeota (21%), and the relative proportions of these two phyla were comparable in the two habitats. In terms of relative abundance, Woesearchaeota and Bathyarchaeota were not significantly different between these two niches; however, specific subclades (Woese-3, Woese-21, Bathy-6, Bathy-18) were significantly enriched in vegetated sediments (), while Thaumarchaeota was favored in unvegetated sites (). Seagrasses are the only flowering plants able to live in seawater and pollinate while submerged. Nonmetric multidimensional scaling plots based on Bray-Curtis distance showing the differences in benthic archaeal community structure between vegetated and unvegetated sediments. This organism infects eelgrass’ leaf. Thank you for your interest in spreading the word about bioRxiv. Based on previous reports, Woesearchaeota might be involved in anaerobic carbon cycling [29] and presented high proportions in certain highly productive environments, such as 20% in the cyanobacteria-dominated Zhushan Bay [30, 31], 30-60% in Bohai and Yellow Sea surface sediments [32], and approximately 20% in mangroves [16, 33, 34]. DNA was extracted from 0.5 to 1.0 g of sediment using a FastDNA Kit for Soil (MP Biomedical, USA) according to the manufacturer’s instructions. Zostera japonica Leaf Bacteroidetes Inaba et al. According to a genomic analysis, Thermoplasmata has the capacity to degrade detrital proteins and long-chain fatty acids [32, 41]. Analogously, this subclade accumulated in the sediments dominated by macrophytes [30] and mangroves [16]. A total of 100,636 raw reads were obtained from the 6 samples, and 33,922 reads were finally retained after quality filtering and removing chimeras and singletons (Table S1). Briefly, three (V1-V3) surface (0-5 cm) sediment samples were randomly collected from the seagrass-vegetated region, and another three control (U1-U3) samples were collected from the adjacent bare (unvegetated) region in the Swan Lake lagoon (Rongcheng Bay, Yellow Sea, China) in May 2013. The quantities of Woesearchaeota in the vegetated sediments increased to twice those in the bare sediments, and the quantities of Woese-3, Woese-10, Woese-13, and Woese-21 were significantly higher in the vegetated sediments (Figures 4(a) and 4(b)). In contrast, Thaumarchaeota was selectively enriched in the bare sediments (Figure 1(a)). The two phyla Aenigmarchaeota () and Lokiarchaeota () appeared to be minor components. Includes pond weeds and relatives; consists of 15 families, 56 genera, and aprox. Sulfurovum, Vibrio, Photobacterium and Woeseia were identified as the shared key seagrass rhizosphere genus. In the present study, the sediment cores of seagrass bed (dominated by Zostera japonica and Zostera marine) and degradation area in Swan Lake (China) were sampled; then, biogeochemical parameters were analyzed, and microbial community composition was investigated by using high-throughput sequencing of the 16S rRNA gene. Zhang, Y.-B. Although Woesearchaeota showed similar proportions in the vegetated and unvegetated sediments (Figure 1(a)), its subclades Woese-3 () and Woese-21 () presented significantly higher proportions in the vegetated sediments, while Woese-20 showed the opposite trend () (Figure 1(b)). In this study, we applied the integrated high-throughput absolute abundance quantification (iHAAQ) method, which has been demonstrated to evaluate the absolute abundance of bacterial subgroups [28, 58, 59]. The Bathy-6 genome was reconstructed from the suboxic and sulfide-depleted shallow sediment layers, which harbor genes encoding enzymes responsible for degrading extracellular plant-derived mono- and polysaccharides [14, 18]. Seagrass colonization alters sediment physicochemical properties by depositing seagrass fibers and releasing organic carbon and oxygen from the roots. Z. marinaleaf blades are characteristically flat and wide (2-12 mm) and can reach up to 3 meters in length (Mondragon and Mondragon, 2003) although morphology is variable and depends on environmental factors such as substrate type (Short, 1983), depth (Lee et al., 2000), temperature (Moore et al., 1996), and light and nutrient availability (Short, 1983). datasets have provided data to the NBN Atlas Scotland for this genus.. Browse the list of datasets and find organisations you can join if you are interested in participating in a survey for species of Zostera Linnaeus, 1753. NBN Atlas Scotland. However, not much is known about marine fungi and even less is known about seagrass associated fungi. Learn seagrass with free interactive flashcards. To thoroughly understand their ecological distribution and significance, the two groups were further divided into subclades based on phylogenetic analyses of their 16S rRNA genes. The name Zostera marina is derived from Greek roots meaning ‘sea girdle’ referring to the way the stems emerge from a sheath (Rucklehaus 1998). Grazing is probably part of the natural seasonal fluctuation in seagrass cover and Zostera sp. The reads assigned to bacteria, unassigned, or singletons (the OTUs containing a single read across all samples) were discarded prior to building the OTU table. Zostera japonica alters physical habitat structure as well as the richness and densities of resident fauna The ML tree was built with the “FastTree” program and edited with the online tool iTOL (http://itol.embl.de/). The amplicons were gel purified and further purified with AMPure beads (Beckman Coulter, USA) and then pooled in equimolar proportions and sequenced on 318 chips with an Ion Torrent Personal Genome Machine (PGM) according to the manufacturer’s instructions (Life Technologies, USA). High-throughput sequencing of 16S rDNA showed that Woesearchaeota, Bathyarchaeota, and Thaumarchaeota were the most abundant phyla across all samples, accounting for approximately 42%, 21%, and 17% of the total archaeal communities, respectively. All samples were homogenized and stored at -80°C until DNA extraction. [11] investigated benthic archaeal diversity in a Zostera noltii meadow using clone library and sequencing and found that Methanobacteria dominated the community. Recently, phylogenetic analysis has shown that the phyla Woesearchaeota and Bathyarchaeota include 26 and 25 subclades, designated as Woese-1 to Woese-26 and Bathy-1 to Bathy-25, respectively [12, 13]. less is known about seagrass associated fungi. To evaluate alpha diversity estimators, we rarefied the high-quality sequences at the lowest number for all samples. After normalization, the OTU numbers of the vegetated and unvegetated samples were estimated to be on average 154 and 143, respectively (Table S1). Sign up here as a reviewer to help fast-track new submissions. The rhizomes creep or ascend, and produce roots and shoots at the nodes. The alpha diversity indexes (OTU richness, Shannon, Simpson, and Chao1) were calculated after resampling using the script alpha_diversity.py. Zostera is a small genus of widely distributed seagrasses, commonly called marine eelgrass or simply eelgrass and also known as seaweed by some fishermen and recreational boaters including yachtsmen. [12] noted that most Woesearchaeota have been reported in midlatitude environments. The metabolic function of Bathy-17 is poorly understood, but according to genomic bins, Bathy-17 can degrade refractory detrital proteins [14]. Beta diversity was calculated based on Bray-Curtis dissimilarities and visualized using nonmetric multidimensional scaling (NMDS) in PRIMER v.6 (Primer-E, UK). Fan, Q.-Y. NBN Atlas Scotland. Sequences for typical Bathyarchaeota subclades according to the nomenclature promoted by Zhou [13] are used as major references for constructing the phylogenetic tree. in shallow sublittoral sediments. Our results indicate that there are many fungal taxa for which a taxonomic assignment cannot be made living on and inside Z. marina leaves, roots and rhizomes and that these plant tissues harbor distinct fungal communities. Epibenthic Relating to the area on top of the sea floor. As the second most abundant phylum, Bathyarchaeota was significantly enriched in seagrass-colonized sediments (vegetated vs. unvegetated, 26.17% vs. 15.44%) (Figure 1(a)), which was consistent with the result for mangroves [13, 16], where Bathyarchaeota generally accounted for more than 40% of the relative abundance in archaeal community, and showed significantly higher proportions in mangrove sites than the nearby mud-flat sediments [16]. Zostera japonica is one of approximately 60 seagrasses, or marine angiosperm species. In this study, we investigated archaeal abundance, diversity, and composition in both vegetated and adjacent bare surface sediments of a Zostera marina meadow. These are . Seagrass beds play essential roles as habitats and hatcheries, in nutrient cycling and in protecting the coastline from erosion. Compared with those in the unvegetated samples ( copies g-1 sediment), the absolute quantity of Woesearchaeota almost doubled in the vegetated samples ( copies g-1 wet sediment; Figure 4(a)). Liang, M.-Y. The raw reads were sorted to the corresponding samples according to the barcodes and filtered to remove reads that (i) were shorter than 110 bases, (ii) exhibited quality scores less than 20, (iii) exhibited ambiguous bases, or (iv) exhibited homopolymer runs with 6 or more bases. Furthermore, putative lignin- and aromatic-degrading genes were identified through metagenomic analysis of Bathy-8 [49]. For example, a greater abundance of the total bacterial community, increased sulfate-reducing activities [8, 9], and higher diversity and abundance of specific bacterial lineages (e.g., diazotrophs) [10] were usually detected in vegetated sediments compared with unvegetated sediments, though the overall bacterial community structure was not significantly different between these two niches [10]. Physical disturbance and removal of plants can lead to increased patchiness and destabilization of the seagrass bed, which in turn can lead to reduced sedimentation within the seagrass bed, increased erosion, and loss of larger areas of Zostera(Davison & Hughes, 1998). The phylum Annelida is composed of segmented worms In the Mediterranean Sea, Annelida species have Drilonereis filum (Claparède, ). Sequencing and phylogenetic analysis of the resulting partial 28S rRNA gene revealed that the organism that this ASV comes from is a member of Novel Clade SW-I in the order Lobulomycetales in the phylum Chytridiomycota. In addition to plant proteins, many microbial proteins, representing refractory organic matter, were buried in the seagrass sediments [8, 9], and Bathy-17 might contribute to degrading this kind of substrate. An example of the morphological diversity of microbial isolates (bacteria, fungi and oomycota) associated with the seagrass, Z. marina. Here we used culture-dependent methods to survey the fungi associated with the seagrass, Zostera marina, also obtaining bacteria and oomycete isolates in the process. Choose from 316 different sets of seagrass flashcards on Quizlet. DNA integrity was checked in a 1.0% agarose gel, and the concentration was measured using a ND-2000C spectrophotometer (NanoDrop, USA). We sampled from two Z. marina beds in Bodega Bay over three time points to investigate Seagrass colonization changes the chemistry and biogeochemical cycles mediated by microbes in coastal sediments. There are about 60 species of fully marine seagrasses which belong to four families ( Posidoniaceae , Zosteraceae , Hydrocharitaceae and Cymodoceaceae ), all in the order Alismatales (in the class of monocotyledons … Beds of seagrass (Zostera marina or Ruppia spp.) [12] (Figure S1). However, not much is known about marine fungi and even less is known about seagrass associated fungi. Eelgrass is found on sandy In this study, we molecularly characterized the diazotrophic assemblages and entire bacterial community in surface sediments of a Zostera marina -colonized coastal lagoon in … The results suggested that different archaeal communities could associate with different seagrass species or depend on the variable local environmental conditions of seagrass meadows. Today I will be blogging about a beautiful marine species called Zostera marina. They may inhabit low, variable and full salinity marine habitats. However, the niche preference of various subclades of Woesearchaeota and Bathyarchaeota in seagrass meadows is unknown [16, 19–21]. Bathyarchaeota and its subclades Bathy-6, Bathy-8, Bathy-15, and Bathy-18 were strongly stimulated by seagrass colonization (Figure 4(c)).
