Ultrastructure of synaptic region in cnb mutants and dync1h1 morphants. TEMs of the photoreceptor synaptic region and outer plexiform layer of 3-dpf embryos. (A) Control morphants (3 ng/embryo) showed well developed synaptic input invaginations (asterisks) and numerous floating ribbons (arrows). (B) dync1h1 morphants (3 ng/embryo) had less defined synaptic input invaginations (asterisk) and significantly reduced number of floating ribbons (arrow). (C) cnb mutants did not show synaptic input invaginations and typically lacked ribbons. MO, morpholino.
