Make the Most Out of Genome Announcements with KBase

Genomics is a dynamic field driven by new technology, massive growth in data, and changes in how scientists share knowledge. This brings new challenges for researchers looking to maximize the impact of their science and ensure the longevity of their data. These changes are especially relevant for the practice of publishing genome announcements. Genome announcements are meant to share and promote newly sequenced organisms with the larger scientific community. A few decades ago, genome announcements were highly anticipated hallmarks of novel science. But, what was once a publishing coup is now an every day event. It is harder and harder to keep abreast of all the genomes that have been sequenced and promote your own new genomes to get the attention and recognition of your research community. Fortunately, KBase can help construct genomes from your sequencing data, generate reports for your announcement, and promote your data to your research community.

KBase Narrative - MRA Genome Announcement Bradyrhizobium NP1

We report the complete genome sequence of Bradyrhizobium strain NP1, which was isolated from forest soil that had been subject to chronic warming. The diverse genus Bradyrhizobium is predicted to contain approximately 800 species (1) and includes non-symbiotic species that dominate forest soil (2). Bradyrhizobium NP1 was isolated from a Long-Term Ecological Research site in the Harvard Forest (HRF), in Petersham, MA (42.54, -72.18).

Best Practices for Successfully Writing and Publishing a Genome Announcement in Microbiology Resource Announcements

Microbiology Resource Announcements (MRA) provides peer-reviewed announcements of scientific resources for the microbial research community. We describe the best practices for writing an announcement that ensures that these publications are truly useful resources. Adhering to these best practices can lead to successful publication without the need for extensive revisions.

Siena College 2022 MRA Genome Announcement Narrative - 6 Isolates

Soil bacteria and endospore forming bacteria in particular play critical environmental roles in biomass degradation, plant health, and many have also been sources for commercially important secondary metabolites including antibiotics. Sequencing multiple isolates of known species also can identify new genes and gene clusters not found in other members of the same species, increasing our understanding of microbial diversity.

6051R & 6051S Assembly and Annotation

We report the draft genomes of two morphologically distinct variants of Bacillus subtilis ATCC 6051 [NCBI3610]. The two isolates exhibit differences in not only morphology but also their genetics, despite identical 16S rRNA sequences. Investigating the genetic differences of colony morphology variation in this model organism can provide valuable insights.

The Roseibium album (Labrenzia alba) Genome Possesses Multiple Symbiosis Factors Possibly Underpinning Host-Microbe Relationships in the Marine Benthos

Here, we announce the genomes of eight Roseibium album (synonym Labrenzia alba ) strains that were obtained from the octocoral Eunicella labiata . Genome annotation revealed multiple symbiosis factors common to all genomes, such as eukaryotic-like repeat protein- and multidrug resistance-encoding genes, which likely underpin symbiotic relationships with marine invertebrate hosts.

Metagenomes and metagenome-assembled genomes from microbial communities in a biological nutrient removal plant operated at Hamptons Road Sanitation District (HRSD) with high and low dissolved oxygen conditions

Aeration is a major cost at biological nutrient removal (BNR) plants. We report on microbial communities in a pilot-scale BNR system before and after a dissolved oxygen transition from 2.5 to 0.2 mg/L implemented over 18 months. Four PacBio metagenomes and 316 metagenome-assembled genomes are announced.

Five draft genome assemblies from Bacillaceae isolated from a degraded wetland environment

Abstract We isolated 5 Bacillaceae from a degraded wetland environment and sequenced their genomes using Illumina NextSeq. Here, we report draft genome sequences of Bacillus velezensus-SC119, Priestia megaterium-SC120, Bacillus zhangzhouensis-SC123, Bacillus pumilis-SC124, and Bacillus idriensis-SC127. The genomes range between 3,657,353 and 5,772,725 base pairs with %GC between 37.62% and 46.38%. Introduction Wetland environments play critical roles in the terrestrial carbon and water cycles and microbial communities are key players in healthy ecosystem function. Endospore forming bacteria in the Bacillaceae family are metabolically and genomically diverse soil heterotrophs that influence plant health, carbon and nitrogen cycling, and often produce diverse natural products that influence other bacterial and non-bacterial species in their environment (1). We collected two soil samples on January 19, 2023 from 42°43'12.7"N 73°45'01.4"W. One was highly hydrated and within a patch of invasive common reeds (Phragmites sp.) and the other was near the base of an Eastern cottonwood tree (Populus deltoides). Bacillus pumilis strain SC124 was isolated from the soil from near the cottonwood tree, while Bacillus velezensis strain SC119, Priestia megaterium strain SC120, Bacillus zhangzhouensis strain SC123, Bacillus idriensis strain SC127 and were isolated from the marshy soil.

Genome collection processing for “Conserved upper thermal limits and small safety margins in soil copiotrophic bacteria”

We extracted the genomic DNA of 400 randomly selected isolates using a Quick-DNA Microprep Kit (Zymo Research D3020) according to the manufacturer’s protocol. We then submitted the extracted gDNA samples for short-read Illumina sequencing (200 Mbp) at SeqCoast Genomics (Portsmouth, NH, USA). After preprocessing the sequences using Trimmommatic (Bolger et al. 2014), we assembled the genomes using SPADES (Bankevich et al. 2012) and checked the quality of each assembly using QUAST (Gurevich et al. 2013). We processed the genome assemblies using a KBase (v1.4.0) pipeline (Allen et al. 2017; Arkin et al. 2018). Briefly, we used DRAM (v0.1.2) with default settings to annotate the genome assemblies. We then evaluated genome quality and possible contamination levels using CheckM (v1.0.18) (Parks et al. 2015) and retained genomes with completeness above 98% and contamination below 5% (n = 354), following the authors' guidelines. We then obtained taxonomic assignments for all remaining isolates using the Genome Taxonomy Database tool GTDB-Tk (v2.3.2, database version r214) (Chaumeil et al. 2019). We constructed a phylogenetic tree using the tool SpeciesTree (v2.2.0). We then trimmed the tree (using Trim SpeciesTree to GenomeSet- v1.4.0), retaining only tips within our collection with measured thermal performance.

Bradyrhizobium sp. WCU1

Bradyrhizobium WCU1 was cultured from a bottle of Vienna-style lager produced in Mexico. Colonies were obtained from beer plated on R2A medium and were slow to grow. A subculture was isolated and BLAST analysis of the 16S rRNA placed it into the genus Bradyrhizobium, with four species matching it at 100% percent identity. These included B. embrapense, B. viridifuturi, B. septentrionale, and B. quebecense. Whole genome phylogenetic analysis identified the two closest relatives of Bradyrhizobium WCU1 to be B. erythrophlei and B. elkanii USDA 76, but at only 91.2 and 90.5% average nucleotide identity (ANI), respectively.

Tolumonas sp. WCU1

Tolumonas sp. WCU1 was cultured from Dicks Creek on the campus of Western Carolina University. Colonies were obtained from water plated on R2A medium. A subculture was isolated and BLAST analysis of the 16S rRNA placed it into the genus Tolumonas, with the highest match at 95.7% percent identity to T. osonensis. Whole genome phylogenetic analysis identified the three species in the genus of Tolumonas to be only 78.1 to 78.5% in average nucleotide identity (ANI). These species include T. auensis , T. osonensis, and T. lignilytica.
