| Minictena luteola gen. and sp. nov, is a small and unusual Cydippida ctenophore, found in the Mediterranean. Its general form and gastrovascular system with stomodeal canals, are similar to those of juvenile Pl.eurobrachiidae. It is characterised by: body semitransparent, yellowish; comb rows equal in length, in pairs from the tip to about the 2/3 of the body length; two apical and unequal pairs of rounded processes; tentacular sheaths of large size apposed to the infundibulum, opening aborally; tentacles with filiform tentilla bearing five types of colloblasts: three of them have a layer of refractive vesicles and a filament with only 1 or 2 spiral turns, the two others have no refractive vesicles and a filament with numerous spiral turns.

| Background: The Planar Cell Polarity pathway (PCP) has been described as the main feature involved in patterning cell orientation in bilaterian tissues. Recently, a similar phenomenon was revealed in cnidarians, in which the inhibition of this pathway results in the absence of cilia orientation in larvae, consequently proving the functional conservation of PCP signaling between Cnidaria and Bilateria. Nevertheless, despite the growing accumulation of databases concerning basal lineages of metazoans, very few information concerning the existence of PCP components have been gathered outside of Bilateria and Cnidaria. Thus, the origin of this module or its prevalence in early emerging metazoans has yet to be elucidated. Results: The present study addresses... |
