Polyphosphate (polyP) exists in all life forms; however, its biological functions in metazoans are understudied. Here, we explored Drosophila as the first genetic model to explore polyP biology in ...

The genome sequence of the sponge Amphimedon queenslandica shows that early metazoans possessed several Hox-like genes of the NK family, but Hox genes themselves arose and expanded only after ...
