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.
Injuries activate the oral identity-specifying canonical Wnt signaling pathway in Hydra, which can trigger head regeneration in permissive tissue contexts created by the absence of pre-existing organizers.
Genomic-profiles and reporters reveal that the three-nucleotide ‘words’ read by the ribosome, codons, have a strong effect on mRNA stability, impacting the homeostatic mRNA and protein levels in human cells.
The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.
Clytia jellyfish regenerate body shape and organs through a mechanically driven process that coordinates tissue remodeling, localized proliferation, and precursor migration and promotes Wnt signaling at a muscle-based landmark.
