The discovery of giant viruses, with capsids as large as some bacteria, megabase-range
genomes and a variety of traits typically found only in cellular organisms, was one of the …

Free-living amoebae of the genus Acanthamoeba are causal agents of a severe sight-
threatening infection of the cornea known as Acanthamoeba keratitis. Moreover, the number …

Here, we provide an update of our review on homeobox genes that we wrote together with
Walter Gehring in 1994. Since then, comprehensive surveys of homeobox genes have …

Horizontal gene transfer (HGT), the movement of genetic material across branches of the
tree of life, is well established in prokaryotes and uncontroversial. This is explained in part …

The opportunistic protist Acanthamoeba, which interacts with other microbes such as
bacteria, fungi, and viruses, shows significant similarity in cellular and functional aspects to …

Acanthamoeba species are infected by the largest known DNA viruses. These include
icosahedral Mimiviruses, amphora-shaped Pandoraviruses, and Pithovirus sibericum, the …

Acanthamoeba is an opportunistic protozoa, which exists widely in nature and is mainly
distributed in soil and water. Acanthamoeba usually exists in two forms, trophozoites and …

Ten years ago, the discovery of Mimivirus, a virus infecting Acanthamoeba, initiated a
reappraisal of the upper limits of the viral world, both in terms of particle size (> 0.7 …

Background The availability of increasing numbers of sequenced genomes has
necessitated a re-evaluation of the evolution of the WRKY transcription factor family. Modern …

Amoebae are protists that have complicated relationships with bacteria, covering the whole
spectrum of symbiosis. Amoeba-bacterium interactions contribute to the study of predation …
