TL;DR: Following the spawning behavior of the European amphioxus during two spawning seasons, it is shown that animals in the field spawn approximately from mid-May through early July, but depending on the year, they show different patterns of spawning.

TL;DR: Elongation of the vertebrate body axis by posterior volumetric growth is linked to increased energy supply and is absent from the externally developing zebrafish embryo.

TL;DR: It is shown that laminins, via heparan sulfate proteoglycans, are instrumental in patterning Bmp responsiveness and that Bmp signalling restricts Engrailed expression to the central domain and underlines the importance of extracellular cues for the precise spatial modulation of cell response to morphogens.

TL;DR: The first report of successful maintenance and spawning of Branchiostoma lanceolatum adults in a facility run on artificial seawater is presented, representing an important step toward further establishing amphioxus as a laboratory animal making it more amenable to experimental research, and hence assists the coming of age of this emerging model.

TL;DR: In this paper, the authors analyzed the effect of the sly/lamc1 mutation in the Laminin γ1 chain on Engrailed expression in pioneers and showed that Bmp-responding cells are excluded from the central domain and this pattern is modulated by laminins, but not by Hedgehog signalling.
