The dynamic genome of Hydra
Comparisons of the Hydra genome to the genomes of other animals shed light on the evolution of epithelia, contractile tissues, developmentally regulated transcription factors, the Spemann–Mangold organizer, pluripotency genes and the neuromuscular junction.
Multiple Wnts are involved in Hydra organizer formation and regeneration.

The results indicate that integration of axial patterning and tissue morphogenesis by the coordinated action of canonical and noncanonical Wnt pathways was crucial for the evolution of eumetazoan body plans.
Cnidarians and the evolutionary origin of the nervous system
In the present review, the anatomical and physiological features of the cnidarian nervous system and the interesting parallels in neurodevelopmental mechanisms between Cnidaria and Bilateria are discussed.
Sequential actions of β-catenin and Bmp pattern the oral nerve net in Nematostella vectensis
It is hypothesize that the consecutive and functionally linked involvement of β-catenin and Bmp signalling in the formation of the cnidarian oral nervous system reflects an ancestral mechanism that evolved before the cNidarian/bilaterian split.

It is found that when modeled in a mammalian host, whereas biofilm formation was not essential for survivability of NTHI in vivo, lipooligosaccharide sialylation was indispensable.
VASCULAR BUDDING, A NEW TYPE OF BUDDING IN BOTRYLLUS ,
In Botryllus primigenus, it has been found that, in addition to palleal budding, new buds are formed also from aggregations of blood-cells at the base of ampullae, and this discovery is of significance in the following three points.
Mitotic chromosome assembly despite nucleosome depletion in Xenopus egg extracts

Combining mouse sperm nuclei and Xenopus cell-free egg extracts depleted of the histone chaperone Asf1 and chromatid-like structures could be assembled even in the near absence of nucleosomes, which challenges the textbook view of mitotic chromosome organization.
Colony-Specificity in Compound Ascidians as Tested by Fusion Experiments
STUDIES ON JAPANESE COMPOUND STYELID ASCIDIANS -II. A NEW SPECIES OF THE GENUS BOTRYLLOIDES AND REDESCRIPTION OF B. VIOLACEUS OKA-
It has become clear that the two forms of Botrylloides mentioned above are quite distinct from each other, and the authors are now facing a taxonomic problem to determine by which of these two forms Botryllid violaceus should be represented.
