A new preprint from us using a single-cell genome pipeline to investigate diversity of uncultured Bodo spp. flagellates.

We isolated 7 Bodo spp. cells from a single environmental sample and show that they represent 3 Bodo sp. each with a unique species of bacterial endosymbiont. #protistsonsky
Single-cell sequencing reveals unexpected genetic diversity among Bodo spp. flagellates and their bacterial endosymbionts
Bodo is a cosmopolitan genus of free living bacterivorous single-celled flagellates in the class Kinetoplastea. Members of genus Bodo are considered the closest free-living relatives to the parasitic ...

Some highlights:
- fully sequenced and annotated genomes of two species, including transposon space using #TEtrimmer for the first time in newly sequenced genomes www.nature.com/articles/s41...
- cultured Arachnopeziza in vitro
- confirmed selective fungicides
- expressed hygromycin resistance +RFP
TEtrimmer: a tool to automate the manual curation of transposable elements - Nature Communications
Transposons are repetitive DNA sequences that are hard to identify and map accurately. TEtrimmer automates key manual steps, enabling faster and more reliable annotation of transposable elements in any genome.

⚠️New paper ➡️ isolating >600 freshwater microbes using dilution-to-extinction and low-nutrient, lake-mimicking media.

🤯Expands cultured diversity to ~70 % of detected genera and enables physiological studies of streamlined oligotrophs.

Bringing the uncultivated microbial majority of freshwater ecosystems into culture - Nature Communications
A large fraction of aquatic bacteria remains uncultured. Here, the authors cultivated 627 strains of abundant freshwater bacteria from 14 European lakes, thus generating a collection that includes many previously uncultured, oligotrophic bacteria that may serve as model organisms.
