Panagrellus redivivus, a free-living nematode often used to study evolution of developmental and behavioural processes in C.elegans has been added to the WS240 release of WormBase.

While its main importance for WormBase is for evolutionary conservation of pathways,P.redivivus is also used as easy to breed microworm feed in aquaculture.

We would like to thank Marissa Macchietto for providing us the data which is also available at the INSDC and as published in Genetics.
