In Drosophila at least 7 genes function zygotically in setting up the dorsoventral axis. Two of these genes, short...

... the specification of the dorsoventral axis and the bilateral axis was examined experimentally. In other species when the dorsal and ventral halves of early echinoderm embryos (preblastula) are separated, the dorsal half often reverses (180°) its dorsoventral axis. We asked whether those larvae with an inverted...

We report here that the dorsoventral polarity of the sea urchin embryo can be disrupted by treatment of embryos with NiCl 2 . Lytechinus...

Our observations raise the possibility that retinoic acid plays a role in the determination and maintenance of the dorsoventral axis of the retina, and that the morphogenetically significant asymmetry here lies...
