Caption

A: Open arrows denote connecting cilia of cone photoreceptors for reference. Then wild type (WT) cone outer segment measures 1.3 um at its widest point and tapers distally; B, cone inner segments were sometimes observed to contain electron-dense granules (stars). C: Disorganized Gucy2e^tm1Gar/Gucy2e^tm1Gar (GC1-/-) cone outer segment reveals apparent partitioning of membrane components; lamellar structures emanate from one side of the distal connecting cilium and vesicles from the tip. D: Adjacent to the retinal pigmented epithelium (RPE), extracellular particle (2-3 um in diameter) containing vesicles and tubules surrounded by membrane lamellae appears as an end product of membrane component sorting. E: Another example of membrane partitioning is shown in which membrane layers are found to one side of the distal connecting cilium and vesicles/tubules extend from its tip. Cones were examined in a location inferior to the optic nerve for each genotype.
