Posterior eyespots in larval chitons have a molecular identity similar to anterior cerebral eyes in other bilaterians
(BioMed Central, 2015-12-22)
Background: Development of cerebral eyes is generally based on fine-tuned networks and closely intertwined with the formation of brain and head. Consistently and best studied in insects and vertebrates, many signaling ...
Owenia fusiformis – a basally branching annelid suitable for studying ancestral features of annelid neural development
(BioMed Central, 2016-06-16)
Background Comparative investigations on bilaterian neurogenesis shed light on conserved developmental mechanisms across taxa. With respect to annelids, most studies focus on taxa deeply nested within the annelid tree, ...
Calcareous sponge genomes reveal complex evolution of α-carbonic anhydrases and two key biomineralization enzymes
(BioMed Central, 2014-11-25)
Background: Calcium carbonate biominerals form often complex and beautiful skeletal elements, including coral exoskeletons and mollusc shells. Although the ability to generate these carbonate structures was apparently ...
Embryonic expression of priapulid Wnt genes
Posterior elongation of the developing embryo is a common feature of animal development. One group of genes that is involved in posterior elongation is represented by the Wnt genes, secreted glycoprotein ligands that signal ...
