The dynamic genome of Hydra
Comparisons of the Hydra genome to the genomes of other animals shed light on the evolution of epithelia, contractile tissues, developmentally regulated transcription factors, the Spemann–Mangold organizer, pluripotency genes and the neuromuscular junction.
Animals in a bacterial world, a new imperative for the life sciences
Recent technological and intellectual advances that have changed thinking about five questions about how have bacteria facilitated the origin and evolution of animals; how do animals and bacteria affect each other’s genomes; how does normal animal development depend on bacterial partners; and how is homeostasis maintained between animals and their symbionts are highlighted.
The innate immune repertoire in Cnidaria - ancestral complexity and stochastic gene loss
Consideration of these patterns of gene distribution underscores the likely significance of gene loss during animal evolution whilst indicating ancient origins for many components of the vertebrate innate immune system.
Transgenic Hydra allow in vivo tracking of individual stem cells during morphogenesis.
The efficient generation of transgenic Hydra lines by embryo microinjection revealed remarkably high motility of individual endodermal epithelial cells during morphogenesis and is expected to become important tools to dissect the molecular mechanisms of development at the base of the Metazoan tree.

The analysis suggests that the Hydra epithelium actively selects and shapes its microbial community, and strongly indicates distinct selective pressures imposed on and within the epithelia.
Defining the origins of the NOD-like receptor system at the base of animal evolution.
First evidence that early diverging metazoans have large and complex NLR repertoires is provided, and induced proximity recruitment of an effector caspase to the HyNLR type 1 protein upon oligomerization indicates a potential role of casp enzyme activation downstream of NLR activation in Hydra.
