Pseudogenes are defined as “non-functional” copies of corresponding parent genes. The
cognition of pseudogenes continues to be refreshed through accumulating and updating …

Tick-borne bacteria of the genera Ehrlichia and Anaplasma cause several emerging human
infectious diseases worldwide. In this study, we conduct an extensive survey for Ehrlichia …

Pathogenic Leptospira are spirochete bacteria which cause leptospirosis, a re-emerging
zoonotic disease of global importance. Here, we use a recently described lineage of …

Many animals are dependent on microbial partners that provide essential nutrients lacking
from their diet. Ticks, whose diet consists exclusively on vertebrate blood, rely on maternally …

Pseudomonas aeruginosa notoriously adapts to the airways of people with cystic fibrosis
(CF), yet how infection-site biogeography and associated evolutionary processes vary as …

Evidence for gene non-functionalization due to mutational processes is found in genomes in
the form of pseudogenes. Pseudogenes are known to be rare in prokaryote chromosomes …

Most fungal viruses are RNA viruses, and no double-stranded DNA virus that infects fungi is
known to date. A recent study detected DNA polymerase genes that originated from large …

Abstract The endosymbiont Candidatus Azoamicus ciliaticola was proposed to generate
ATP for its eukaryotic host, an anaerobic ciliate of the Plagiopylea class, fulfilling a function …

Timing the acquisition of a beneficial microbe relative to the evolutionary history of its host
can shed light on the adaptive impact of a partnership. Here, we investigated the onset and …

Arsenophonus is a widespread insect symbiont with life strategies that vary from parasitism
to obligate mutualism. In insects living exclusively on vertebrate blood, mutualistic …
