Comprehensive analysis of the microbial consortium in the culture of flagellate Monocercomonoides exilis
Monocercomonoides exilis is the only known amitochondriate eukaryote, making it an excellent model for studying the implications of mitochondrial reduction from a cellular and evolutionary point of view. Although M.bioRxiv
Small but mitey: long-read assembly of a streamlined mite genome from contaminated host plant sequencing data
Technological advances have propelled DNA sequencing of non-model organisms, making sequencing more accessible and cost effective, which has also increased the availability of raw data in public repositories.bioRxiv
Chimeric origin of eukaryotes from Asgard archaea and ancestral giant viruses
The details surrounding the evolution of complex cells remain some of the most enduring mysteries in biology.bioRxiv
The Ribosomal Operon Database (ROD): A full-length rDNA operon database extracted from genome assemblies
Current rDNA reference sequence databases are tailored towards shorter DNA markers, such as parts of the 16/18S marker or the ITS region.bioRxiv
MotifScope: a multi-sample motif discovery and visualization tool for tandem repeats
Tandem repeats (TRs) constitute a significant portion of the human genome, exhibiting high levels of polymorphism due to variations in size and motif composition.bioRxiv
Universal signatures of transposable element compartmentalization across eukaryotic genes
The evolutionary mechanisms shaping the origins of genome architecture remain poorly understood but can now be assessed with unprecedented power due to the abundance of genome assemblies spanning phylogenetic diversity.bioRxiv
Systematic identification of cargo-carrying genetic elements reveals new dimensions of eukaryotic diversity
Cargo-carrying mobile elements (CCEs) are genetic entities that transpose diverse protein coding sequences. Although common in bacteria, we know little about the biology of eukaryotic CCEs because no appropriate tools exist for their annotation.bioRxiv
Polinton-like Viruses Associated with Entomopoxviruses Provide Insight into Replicon Evolution
Polinton-like viruses (PLVs) are a diverse group of small integrative dsDNA viruses that infect diverse eukaryotic hosts. Many PLVs are hypothesized to parasitize viruses in the phylum Nucleocytoviricota for their own propagation and spread.bioRxiv
Phage-plasmids promote genetic exchanges between phages and plasmids and create novel ones.
Phages and plasmids have key roles in bacterial evolution and are usually very different. Yet, they must recombine, since they sometimes carry nearly identical accessory genes.bioRxiv
A patchwork pathway of apparently recent origin enables degradation of the synthetic buffer compound TRIS in bacteria
The widely used synthetic chemical 2-amino-2-hydroxymethyl-propane-1,3-diol (TRIS) was long considered to be biologically inert. Herein, we describe a complete degradation pathway for the catabolism of TRIS in bacteria.bioRxiv
Phages... So many #phage and they are all #prophage integrated into a #bacteria #genome
A few million prophages from > million bacterial genomes
Are prophages good or bad for bacteria? The data shows they provide heaps of benefits

The Promise and Pitfalls of Prophages
Phages dominate every ecosystem on the planet. While virulent phages sculpt the microbiome by killing their bacterial hosts, temperate phages provide unique growth advantages to their hosts through lysogenic conversion.bioRxiv
Community diversity affects functionality and species sorting during propagation of a natural microbial community
The influence of community diversity on community function has long been a central question in ecology. Particularly, the dynamics over time of this relationship as a function of levels of diversity remains unclear.bioRxiv
Repeatability of adaptation in sunflowers: genomic regions harbouring inversions also drive adaptation in species lacking an inversion
Local adaptation commonly involves alleles of large effect, which experience fitness advantages when in positive linkage disequilibrium (LD).bioRxiv
