The symbiotic relationship between Hydra and Chlorella is driven by metabolic co-dependence and characterized by changes in the photobiont genome in terms of lack of genes essential in free-living algae.
The 3Å structure and correlated functional analysis of the TRPM2 cation channel from Nematostella vectensis shed light on the molecular mechanisms of TRPM2 regulation by intra- and extracellular Ca2+, and of inactivation of human TRPM2.
Different developmental stages of a venomous animal (e.g. Nematostella vectensis) with a complex life cycle produce vastly different venoms that can serve in different antagonistic interactions with other species.
The foundations of genomic complexity in multicellular animals have deep roots in their unicellular prehistory, both in terms of innovations in gene content, as well as the evolutionary dynamics of genome architecture.
The colonization of corals and their relatives by intracellular microalgae is facilitated by immunity proteins in the animal that contain thrombospondin-type-1 repeats, elucidating the inter-partner recognition processes required for the establishment of this ecologically important symbiosis.
The coding sequences of a very highly conserved family of neurogenic transcription factors from different species have evolved to generate proteins that have different life times causing them to display quantitatively different neural induction potentials.
An unbiased transcriptomic approach reveals that developing paddlefish electrosensory organs express genes essential for mechanosensory hair cell development and synaptic transmission, and identifies candidates for mediating electroreceptor development and function.
