A novel tail: One story from the rare taxa of the coal seam microbiome

A substantial portion of global coal seam methane reserves are biogenically produced. To enhance methane production, recent research has focussed on genetic surveying of the microbial life inhabiting these coal seams. These surveys have revealed that the most abundant organisms in these microbial communities are taxa specialised in metabolism of various simple substrates, and are typically methanogens, their (presumably) syntrophic acetate-oxidising bacterial partners, and other bacterial taxa associated with biomass recycling. Although abundant, these microbes are incapable of directly accessing the vast majority of recalcitrant carbon contained within the coal geopolymer. Instead, these more abundant taxa likely rely on the low abundance but diverse taxa, known as the ‘rare taxa’, to transform the carbon within coal into simpler, more labile substrates. Since these rare taxa typically have low taxonomic resolution, their probable activities within the coal seam environment are difficult to infer using the standard 16S rDNA community surveys. Therefore, the present study aimed to develop a method for identifying and characterising these rare taxa using a metagenomic approach. Using this method, a near-complete genome from a Deltaproteobacteria sp. (CSMB_808; designation taken from the Coal Seam Microbiome reference set) was recovered from a metagenome sampling the Surat Basin, Australia, and comprised only 0.5% of the total 16S rDNA sequences recovered from this metagenome. Genetically, CSMB_808 appears to be a motile fatty acid and possibly alkane-degrader within the coal seam environment, and may play an important role in the coal-to-methane degradative pathways. Despite the near-completeness of the recovered genome, the taxonomic resolution of this deltaproteobacterium was unable to be clarified due to insufficient described close relatives. Together, the low taxonomic resolution, relatively low 16S rDNA abundance, and ability to degrade putative upstream metabolites that may facilitate methanogenesis in the coal seam environment, indicates that this method of analysis can assist in understanding other important but uncharacterised rare taxa of the coal seam microbiome. A clearer understanding of the function of these taxa would allow targeted strategies to enhance methane production, as well as contributing valuable knowledge of carbon cycling in the terrestrial subsurface.

Extracellular oil production by Rhodotorula paludigena BS15 for biorefinery without complex downstream processes.

To realize biomass refinery without complex downstream processes, we extensively screened for microbial strains that efficiently produce extracellular oil from sugars. Rhodotorula paludigena (formerly Rhodosporidium paludigenum) BS15 was found to efficiently produce polyol esters of fatty acids (PEFAs), which mainly comprised of 3-acetoxypalmitic acid and partially acetylated mannitol/arabinitol. To evaluate the performance of this strain, fed-batch fermentation was demonstrated on a flask scale, and 110g/L PEFA and 103g/L dry cells were produced in 12days. To the best of our knowledge, the strain BS15 exhibited the highest PEFA titer (g/L) ever to be reported so far. Because the PEFA precipitated at the bottom of the culture broth, it could be easily recovered by simply discarding the upper phase. Various carbon sources can be utilized for cell growth and/or PEFA production, which signifies the potential for converting diverse biomass sources. Two different types of next-generation sequencers, Illumina HiSeq and Oxford Nanopore PromethION, were used to analyze the whole-genome sequence of the strain BS15. The integrative data analysis generated a high-quality and reliable reference genome for PEFA-producing R. paludigena. The 22.5-M base genome sequence and the estimated genes were registered in Genbank (accession numbers BQKY01000001-BQKY01000019). KEY POINTS: • R. paludigena BS15 was isolated after an extensive screening of extracellular oil producers from natural sources. • Fed-batch fermentation of R. paludigena BS15 yielded 110g/L of PEFA, which is the highest titer ever reported to date. • Combined analysis using Illumina and Oxford Nanopore sequencers produced the near-complete genome sequence.

Symptomatic, widespread, and inconspicuous: new detection of tomato fruit blotch virus

Tomato production is an important part of the Swiss vegetable production with most tomato crops grown in greenhouses. Tomato plants are vulnerable to diseases caused by viruses, which can have significant impacts on crop production. This study reports the first detection of tomato fruit botch virus (ToFBV, Blunervirus solani) in Switzerland, from a tomato production site at the southern part of the Ticino region. The symptoms observed indicated presence of a viral pathogen, but tests against the most common tomato viruses were negative. Immunocapture of double-stranded RNA and its subsequent sequencing on a Flongle flowcell (Oxford Nanopore Technologies) identified the presence of ToFBV and southern tomato virus. The genome of the Swiss ToFBV isolate was very similar to that available in GenBank. Datamining of the sequence read archives found the virus in two other countries, with a highly conserved genome. With this study, there are now 12 near-complete genomes of ToFBV available, and the virus is recorded from ten countries. This study underlines the importance of continuous monitoring and research on emerging viruses in tomato production.

Trichocoleus desertorum isolated from Negev desert petroglyphs: Characterization, adaptation and bioerosion potential

The Negev petroglyphs are considered valuable cultural heritage sites, but unfortunately, they are exposed to deterioration processes caused by anthropogenic and natural forces. Despite the many studies that have already pointed to the role of cyanobacteria in biogenic rock weathering, the knowledge involved in the process is still lacking. In this study, a cyanobacterial strain was isolated from the Negev Desert petroglyphs aiming to reveal its involvement in geochemical cycles and in the weathering processes of the rock substrate. The strain was characterized using morphological, molecular, and microscopic studies. The morphological research revealed a green-bluish, bundle-forming filamentous strain characterized by trichomes embedded in a common sheath. A combination of Nanopore and Illumina sequencing technologies facilitated the assembly of a near-complete genome containing 5,458,034 base pairs. A total of 5027 coding sequences were revealed by implementing PROKKA software. Annotation of five replicas of the 16S ribosomal RNA genes revealed that the Negev cyanobacteria isolate is closely (99.73 %) related to Trichocoleus desertorum LSB90_MW403957 isolated from the Sahara Desert, Algeria. The local strain was thus named Trichocoleus desertorum NBK24 CP116619. Several gene sequences that code for possible environmental adaptation mechanisms were found. Our study also identified genes for membrane transporters involved in the exchange of chemical elements, suggesting a possible interaction with rock minerals. Microscopic observations of T. desertorum NBK24 CP116619 infected onto calcareous stone slabs under laboratory conditions demonstrated the effect of the isolated cyanobacteria on stone surface degradation. In conclusion, the findings of this study further our understanding of terrestrial cyanobacterial genomes and functions and highlight the role of T. desertorum NBK24 CP116619 in stone weathering processes. This information may contribute to the creation of efficient restoration strategies for stone monuments affected by cyanobacteria.

A meta-omics approach to explore the biofuel-producing enzyme potential from extreme environmental conditions

Geothermally warmed spring water contaminated with decomposed leaf biomass are unique hot spring ecosystems , are expected to support the recycling of various nutrients and to host lignocellulose degrading thermostable enzymes, genes and bacteria. An attempt is made in the present study to explore CAZymes in a carbohydrate-contaminated unique environment at Deulajhari spring through a multi-omics approach using an indigenous consortium developed from the spring sediment. Co-assembly of shotgun metagenome and metatranscriptome libraries from the Deulajhari hot spring consortia sample recovered seventeen refined, high-quality near-complete genomes. The predominant recovery of thermophilic aerobic chemo-heterotrophic Meiothermus and Rhodothermus has been observed through genome reconstruction. The reported production of an array of enzymes, including xylanase, β-xylosidase, endoglucanase and polysaccharide deacetylase, establishes their lignocellulose-degrading ability. The unexpected strong positive correlation between predominating Meiothermus and less prevailing members of Acetobacteraceae, unclassified Gaiellaceae, unclassified Burkholderiaceae and Tepidimonas of the consortium signifies their unexplored role in biomass degradation. Furthermore, the synergistic involvement of the diverse enzymes represented by a vast gene repertoire is responsible for the degradation of complex plant polysaccharides by the group of bacteria. The novelty of the present study stems from the identification of a diverse range of potential lignocellulose-digesting enzymes expressed by the bacterial consortium. This finding emphasizes the significant potential of these enzymes in facilitating industrial-scale production of biofuel, making it a notable contribution to the field.

Analysis of Cotton Leafroll Dwarf Virus P0 Gene Sequences from South Carolina Reveals Low Variability Among Isolates.

Cotton leafroll dwarf virus (CLRDV) is emerging across the major cotton-producing states of the southern United States. Because it was detected in nearly all cotton-producing states within a few years of its initial detection in the United States, the spread of the virus has apparently occurred rapidly. In this study spanning three growing seasons in South Carolina, we collected CLRDV isolates from symptomatic and asymptomatic cotton plants in 10 counties. The genomic region encoding P0, the viral suppressor of RNA silencing, was sequenced and compared among CLRDV isolates. Low variability among CLRDV P0 sequences from South Carolina isolates with similarities to other United States isolates was revealed by amino acid sequence alignment and phylogenetic analysis. Low variability among South Carolina isolates was also confirmed by sequencing a subset of eight near-complete genomes of CLRDV isolates. Although sequence variability was low among South Carolina isolates, this data should be taken in the context of all United States isolates, for which diversity may be higher than initially expected. Sequences gathered in this study add to the body of knowledge on CLRDV diversity in the United States.

Integrated Human Skin Bacteria Genome Catalog Reveals Extensive Unexplored Habitat-Specific Microbiome Diversity and Function.

The skin is the largest organ in the human body. Various skin environments on its surface constitutes a complex ecosystem. One of the characteristics of the skin micro-ecosystem is low biomass, which greatly limits a comprehensive identification of the microbial species through sequencing. In this study, deep-shotgun sequencing (average 21.5Gigabyte (Gb)) from 450 facial samples and publicly available skin metagenomic datasets of 2069 samples to assemble a Unified Human Skin Genome (UHSG) catalog is integrated. The UHSG encompasses 813 prokaryotic species derived from 5779 metagenome-assembled genomes, among which 470 are novel species covering 20 phyla with 1385 novel assembled genomes. Based on the UHSG, the core functions of the skin microbiome are described and the differences in amino acid metabolism, carbohydrate metabolism, and drug resistance functions among different phyla are identified. Furthermore, analysis of secondary metabolites of the near-complete genomes further find 1220 putative novel secondary metabolites, several of which are found in previously unknown genomes. Single nucleotide variant (SNV) reveals a possible skin protection mechanism: the negative selection process of the skin environment to conditional pathogens. UHSG offers a convenient reference database that will facilitate a more in-depth understanding of the role of skin microorganisms in the skin.

Chromosomal organization of biosynthetic gene clusters, including those of nine novel species, suggests plasticity of myxobacterial specialized metabolism.

Natural products discovered from bacteria provide critically needed therapeutic leads for drug discovery, and myxobacteria are an established source for metabolites with unique chemical scaffolds and biological activities. Myxobacterial genomes accommodate an exceptional number and variety of biosynthetic gene clusters (BGCs) which encode for features involved in specialized metabolism. In this study, we describe the collection, sequencing, and genome mining of 20 myxobacteria isolated from rhizospheric soil samples collected in North America. Nine isolates were determined to be novel species of myxobacteria including representatives from the genera Archangium, Myxococcus, Nannocystis, Polyangium, Pyxidicoccus, Sorangium, and Stigmatella. Growth profiles, biochemical assays, and descriptions were provided for all proposed novel species. We assess the BGC content of all isolates and observe differences between Myxococcia and Polyangiia clusters. Continued discovery and sequencing of novel myxobacteria from the environment provide BGCs for the genome mining pipeline. Utilizing complete or near-complete genome sequences, we compare the chromosomal organization of BGCs of related myxobacteria from various genera and suggest that the spatial proximity of hybrid, modular clusters contributes to the metabolic adaptability of myxobacteria.

Target capture sequencing for the first Nigerian genotype I ASFV genome.

African swine fever (ASF) is a contagious viral disease that affects domestic pigs and wild boars, causing significant economic losses globally. After the first Nigerian outbreak in 1997, there have been frequent reports of ASF in pig-producing regions in the country. To facilitate control, it is important to understand the genotype and phylogenetic relationship of ASF viruses (ASFVs). Recent genetic analysis of Nigerian ASFV isolates has revealed the presence of both genotypes I and II; this is based on analysis of a few selected genes. Phylogenetic analysis of ASFV whole genomes highlights virus origins and evolution in greater depth. However, there is currently no information on the ASFV genome from Nigerian isolates. Two ASFV-positive samples were detected during a random survey of 150 Nigerian indigenous pig samples collected in 2016. We assembled near-complete genomes of the two ASFV-positive samples using in-solution hybrid capture sequencing. The genome-wide phylogenetic tree assigned these two genomes into p72 genotype I, particularly close to the virulent Benin 97/1 strain. The two ASFVs share 99.94 and 99.92 % genomic sequence identity to Benin97/1. This provides insight into the origin and relationship of ASFV strains from Nigeria and Italy. The study reports for the first time the determination of near-complete genomes of ASFV using in-solution hybrid capture sequencing, which represents an important advance in understanding the global evolutionary landscape of ASFVs.

Expanding the range of the respiratory infectome in Australian feedlot cattle with and without respiratory disease using metatranscriptomics

BackgroundBovine respiratory disease (BRD) is one of the most common diseases in intensively managed cattle, often resulting in high morbidity and mortality. Although several pathogens have been isolated and extensively studied, the complete infectome of the respiratory complex consists of a more extensive range unrecognised species. Here, we used total RNA sequencing (i.e., metatranscriptomics) of nasal and nasopharyngeal swabs collected from animals with and without BRD from two cattle feedlots in Australia.ResultsA high abundance of bovine nidovirus, influenza D, bovine rhinitis A and bovine coronavirus was found in the samples. Additionally, we obtained the complete or near-complete genome of bovine rhinitis B, enterovirus E1, bovine viral diarrhea virus (sub-genotypes 1a and 1c) and bovine respiratory syncytial virus, and partial sequences of other viruses. A new species of paramyxovirus was also identified. Overall, the most abundant RNA virus, was the bovine nidovirus. Characterisation of bacterial species from the transcriptome revealed a high abundance and diversity of Mollicutes in BRD cases and unaffected control animals. Of the non-Mollicutes species, Histophilus somni was detected, whereas there was a low abundance of Mannheimia haemolytica.ConclusionThis study highlights the use of untargeted sequencing approaches to study the unrecognised range of microorganisms present in healthy or diseased animals and the need to study previously uncultured viral species that may have an important role in cattle respiratory disease.9Ej9w1gXTXyGbc-DCpnuD_Video

Genomic characterization of Alphacoronavirus from Mops condylurus bats in Nigeria

Coronaviruses (CoVs) are responsible for sporadic, epidemic and pandemic respiratory diseases worldwide. Bats have been identified as the reservoir for CoVs. To increase the number of complete coronavirus genomes in Africa and to comprehend the molecular epidemiology of bat Alphacoronaviruses (AlphaCoVs), we used deep metagenomics shotgun sequencing to obtain three (3) near-complete genomes of AlphaCoVs from Mops condylurus (Angolan free-tailed) bat in Nigeria. Phylogenetic and pairwise identity analysis of open reading frame 1ab (ORF1ab), spike (S), envelope (E), membrane (M) and nucleocapsid (N) genes of AlphaCoV in this study to previously described AlphaCoVs subgenera showed that the Nigerian AlphaCoVs may be members of potentially unique AlphaCoV subgenera circulating exclusively in bats in the Molossidae bat family. Recombination events were detected, suggesting the evolution of AlphaCoVs within the Molossidae family. The pairwise identity of the S gene in this study and previously published S gene sequences of other AlphaCoVs indicate that the Nigerian strains may have a genetically unique spike protein that is distantly related to other AlphaCoVs. Variations involving non-polar to polar amino acid substitution in both the Heptad Repeat (HR) regions 1 and 2 were observed. Further monitoring of bats to understand the host receptor use requirements of CoVs and interspecies CoV transmission in Africa is necessary to identify and prevent the potential danger that bat CoVs pose to public health.

A high-quality genome assembly highlights the evolutionary history of the great bustard (Otis tarda, Otidiformes)

Conservation genomics often relies on non-invasive methods to obtain DNA fragments which limit the power of multi-omic analyses for threatened species. Here, we report multi-omic analyses based on a well-preserved great bustard individual (Otis tarda, Otidiformes) that was found dead in the mountainous region in Gansu, China. We generate a near-complete genome assembly containing only 18 gaps scattering in 8 out of the 40 assembled chromosomes. We characterize the DNA methylation landscape which is correlated with GC content and gene expression. Our phylogenomic analysis suggests Otidiformes and Musophagiformes are sister groups that diverged from each other 46.3 million years ago. The genetic diversity of great bustard is found the lowest among the four available Otidiformes genomes, possibly due to population declines during past glacial periods. As one of the heaviest migratory birds, great bustard possesses several expanded gene families related to cardiac contraction, actin contraction, calcium ion signaling transduction, as well as positively selected genes enriched for metabolism. Finally, we identify an extremely young evolutionary stratum on the sex chromosome, a rare case among birds. Together, our study provides insights into the conservation genomics, adaption and chromosome evolution of the great bustard.

Identification and genetic characteristics of tusavirus in fecal samples of patients with chronic diseases in Guangzhou, China.

The Tunisian stool-associated parvovirus [Tusavirus (TuV)] is a novel member of the genus Protoparvovirus, which may be linked to diarrhea. Herein, we investigated the prevalence of TuV in different populations and analyzed its genetic and bioinformatic characteristics. This study was conducted in a tertiary hospital in Guangzhou (China) from February 2018 to July 2022. Demographic and clinical information and stool samples were collected from individuals who visited the hospital. ProtScale, SwissModel, Datamonkey, and other tools were used to analyze and predict the physicochemical parameters, tertiary structure, selection pressure, and B-cell epitopes of capsid viral protein 2 of TuV (VP2-TuV). A total of 3,837 participants were enrolled, among which two stool samples from patients with chronic illnesses were tested positive for TuV DNA. However, no positive sample was detected among patients with diarrhea. Two near-complete genome sequences were amplified. The genetic analysis revealed the presence of diversity among TuVs isolated from distinct host species. Bioinformatics analysis revealed that VP2-TuV exhibited hydrophilic properties and lacked transmembrane domains and signal peptides. The secondary structure of VP2-TuV was composed mainly of random coils and β-strands. Selective-pressure analysis of the VP2 region suggested that TuV primarily underwent negative selection during evolution. Negatively selected codon sites coincided with residues comprising of B-cell epitopes, suggesting minimal changes in the immunogenicity of TuV over time. TuV was detected in patients with chronic diseases but not in patients with diarrhea. The putative roles of TuV in the pathogenicity of human diseases and zoonotic viruses must be determined by additional studies.

A near-complete genome assembly of Thalia dealbata Fraser (Marantaceae).

This study presents a chromosome-level, near-complete genome assembly of Thalia dealbata (Marantaceae), a typical emergent wetland plant with high ornamental and environmental value. Based on 36.99 Gb PacBio HiFi reads and 39.44 Gb Hi-C reads, we obtained a 255.05 Mb assembly, of which 251.92 Mb (98.77%) were anchored into eight pseudo-chromosomes. Five pseudo-chromosomes were completely assembled, and the other three had one to two gaps. The final assembly had a high contig N50 value (29.80 Mb) and benchmarking universal single-copy orthologs (BUSCO) recovery score (97.52%). The T. dealbata genome had 100.35 Mb repeat sequences, 24,780 protein-coding genes, and 13,679 non-coding RNAs. Phylogenetic analysis revealed that T. dealbata was closest to Zingiber officinale, whose divergence time was approximately 55.41 million years ago. In addition, 48 and 52 significantly expanded and contracted gene families were identified within the T. dealbata genome. Moreover, 309 gene families were specific to T. dealbata, and 1,017 genes were positively selected. The T. dealbata genome reported in this study provides a valuable genomic resource for further research on wetland plant adaptation and the genome evolution dynamics. This genome is also beneficial for the comparative genomics of Zingiberales species and flowering plants.

Genomic analysis of Kazachstania aerobia and Kazachstania servazzii reveals duplication of genes related to acetate ester production.

Kazachstania aerobia and Kazachstania servazzii can affect wine aroma by increasing acetate ester concentrations, most remarkably phenylethyl acetate and isoamyl acetate. The genetic basis of this is unknown, there being little to no sequence data available on the genome architecture. We report for the first time the near-complete genome sequence of the two species using long-read (PacBio) sequencing (K. aerobia 20 contigs, one scaffold; and K. servazzii 22 contigs, one scaffold). The annotated genomes of K. aerobia (12.5 Mb) and K. servazzii (12.3 Mb) were compared to Saccharomyces cerevisiae genomes (laboratory strain S288C and wine strain EC1118). Whilst a comparison of the two Kazachstania spp. genomes revealed few differences between them, divergence was evident in relation to the genes involved in ester biosynthesis, for which gene duplications or absences were apparent. The annotations of these genomes are valuable resources for future research into the evolutionary biology of Kazachstania and other yeast species (comparative genomics) as well as understanding the metabolic processes associated with alcoholic fermentation and the production of secondary 'aromatic' metabolites (transcriptomics, proteomics and metabolomics).

A near-complete genome assembly of the allotetrapolyploid Cenchrus fungigraminus (JUJUNCAO) provides insights into its evolution and C4 photosynthesis

JUJUNCAO (Cenchrus fungigraminus; 2n = 4x = 28) is a Cenchrus grass with the highest biomass production among cultivated plants, and it can be used for mushroom cultivation, animal feed, and biofuel production. Here, we report a nearly complete genome assembly of JUJUNCAO and reveal that JUJUNCAO is an allopolyploid that originated ∼2.7 million years ago (mya). Its genome consists of two subgenomes, and subgenome A shares high collinear synteny with pearl millet. We also investigated the genome evolution of JUJUNCAO and suggest that the ancestral karyotype of Cenchrus split into the A and B ancestral karyotypes of JUJUNCAO. Comparative transcriptome and DNA methylome analyses revealed functional divergence of homeologous gene pairs between the two subgenomes, which was a further indication of asymmetric DNA methylation. The three types of centromeric repeat in the JUJUNCAO genome (CEN137, CEN148, and CEN156) may have evolved independently within each subgenome, with some introgressions of CEN156 from the B to the A subgenome. We investigated the photosynthetic characteristics of JUJUNCAO, revealing its typical C4 Kranz anatomy and high photosynthetic efficiency. NADP-ME and PEPCK appear to cooperate in the major C4 decarboxylation reaction of JUJUNCAO, which is different from other C4 photosynthetic subtypes and may contribute to its high photosynthetic efficiency and biomass yield. Taken together, our results provide insights into the highly efficient photosynthetic mechanism of JUJUNCAO and provide a valuable reference genome for future genetic and evolutionary studies, as well as genetic improvement of Cenchrus grasses.

Ancient Mitogenomes Reveal Stable Genetic Continuity of the Holocene Serows.

As one of the remaining species of Caprinae only found in Asia, serows (Capricornis) and their classification and conservation have received increasing attention in recent years. However, their evolutionary history and population dynamics are not yet clear. To shed light on these topics, we report the first near-complete ancient mitochondrial genomes from two serow sub-fossils (CADG839 and CADG946) dating to 8860 ± 30 years and 2450 ± 30 years, and incorporate the newly obtained mitogenomes into the dataset of living serows (18 complete mitochondrial genomes drawn from National Center for Biotechnology Information, NCBI) to investigate their relationships and evolution. Phylogenetic results support four clades of serows that can be further divided into five subclades, indicating higher genetic diversity than previously thought. Notably, our two ancient samples do not form a separate branch but belong to Capricornis sumatraensis clade A together with modern individuals, which suggests genetic continuity between ancient and modern serows. Furthermore, our results suggest that the maternal divergences of serows occurred at the beginning of the Pleistocene. Bayesian estimation indicates that the first divergence among all serows happened approximately 2.37 Ma (95% highest posterior density, HPD: 2.74-2.02 Ma) when Japanese serow (Capricornis crispus) appeared, while the last divergence occurred within the Sumatran serow (C. sumatraensis clade A and B) around 0.37-0.25 Ma. Additionally, we found the effective maternal population size of C. sumatraensis increased around 225-160 and 90-50 ka, then remained stable since 50 ka. Overall, our study provides new insights into serow phylogeny and evolutionary history.

Near-Complete Genome Sequence of White Spot Syndrome Virus Infecting Cultivated Shrimp (Penaeus vannamei) in Peru.

White spot syndrome virus (WSSV) infects a broad range of aquatic animals, including the shrimp Penaeus vannamei. In this study, we report one genome sequence of WSSV present in shrimp on the north coast of Peru.
