Siphonophores are colonial hydrozoans, characterized by complex colony organization and
unparalleled zooid functional specialization. Recent genomic studies have offered an …

Epithelia are the first organized tissues that appear during development. In many animal
embryos, early divisions give rise to a polarized monolayer, the primary epithelium, rather …

Brachyury, a member of T-box gene family, is widely known for its major role in mesoderm
specification in bilaterians. It is also present in non-bilaterian metazoans, such as …

Background Aurelia aurita (Scyphozoa, Cnidaria) is an emblematic species of the jellyfish.
Currently, it is an emerging model of Evo-Devo for studying evolution and molecular …

Background The avian node is the equivalent of the amphibian Spemann's organizer, as
indicated by its ability to induce a secondary axis, cellular contribution, and gene …

Most hydrozoan cnidarians form complex colonies varying in the size, shape, and branching
patterns. However, little is known about molecular genetic mechanisms responsible for the …

The life cycle of the common ancestor of Metazoa is a widely debated topic in EvoDevo. This
is intimately linked to a number of questions, such as how the larva appeared in the …

Hydrozoan cnidarians are widely known for a diversity of life cycles. While some hydrozoan
polyps produce medusae, in most species the gonophore remains attached to the polyp …

Endomesoderm specification based on a maternal β-catenin signal and axial patterning by
interpreting a gradient of zygotic Wnt/β-catenin signalling was suggested to predate the split …
