Microbial communities are usually highly diverse and often involve multiple strains from the participating species due to the rapid evolution of microorganisms. In such a complex microecosystem, different strains may show different biological functions. While reconstruction of individual genomes at the strain level is vital for accurately deciphering the composition…

Get reference genome from Kraken2 taxID 0 I have a ~10Gb ONT metagenome from citrus psyllid that I am trying to extract bacterial contigs from to assemble. My current thought for a pipeline is broadly as follows: Tentative ID of each contig with Kraken2, then QC to only take assignments…

16S is a very conserved sequence, which is why it’s used for targeted phylogenetic analysis; it makes it easy to amplify and analyse. Unfortunately that conservation is an issue with minimap2, which is built around the idea that matching scattered subsequences within a sequence is good enough for identifying matches…

A large number of microorganisms in nature cannot be cultivated under laboratory conditions by pure culture methods, and the technical methods of traditional microbiology limit the research on environmental microorganisms. The rapid development of high-throughput omics technology has enabled humans to have an unprecedented understanding of the complex microbial communities…

INTRODUCTION Next-generation sequencing (NGS) has revolutionized many areas of biological research (1, 2), providing ever-more data at an ever-decreasing cost. One such area is microbiome research, the study of microbes in their theater of activity using metagenomic sequencing (3). Here, deep short-read sequencing, and improving performance of long-read sequencing, are…

Abstract Background: Large scale metagenome assembly and binning to generate metagenome-assembled genomes (MAGs) has become possible in the past five years. As a result, millions of MAGs have been produced and increasingly included in pan-genomics workflow. However, pan-genome analyses of MAGs may suffer from the known issues with MAGs: fragmentation,…

Abstract Genome binning has been essential for characterization of bacteria, archaea, and even eukaryotes from metagenomes. Yet, no approach exists for viruses. We developed vRhyme, a fast and precise software for construction of viral metagenome-assembled genomes (vMAGs). vRhyme utilizes single- or multi-sample coverage effect size comparisons between scaffolds and employs…

Lichen fungi live in a symbiotic association with unicellular phototrophs and have no known aposymbiotic stage. A recent study postulated that some of them have lost mitochondrial oxidative phosphorylation and rely on their algal partners for ATP. This claim originated from an apparent lack of ATP9, a gene encoding one subunit…

Antibiotic discovery rates dramatically declined following the “golden age” of the 1940’s to the 1960’s. The platforms that underpinned that age of discovery rested upon laboratory cultivation of a small clade of bacteria, the actinomycetes, primarily isolated from soil environments. Fermentation extracts of these isolated bacteria have provided the majority…
