    Notizen: Abstract. Immunohistochemical and physiological studies on various insect photoreceptors have demonstrated that the Na,K-ATPase (sodium pump) is restricted to the nonreceptive nonmicrovillar area of the plasma membrane. Here, we examined the distribution of the Na,K-ATPase in photoreceptor cells of the superposition-type compound eye in the moth Manduca sexta. Using immunofluorescent and immunogold cytochemistry, we show that the Na,K-ATPase is localized to both the nonmicrovillar and the microvillar parts of the plasma membrane. Manduca photoreceptors thus deviate from the common concept that the sodium pump and the molecular components of the photoreceptive machinery reside on different domains of the plasma membrane.

    Notizen: Abstract. Light stimulation of locust photoreceptors causes a translocation of submicrovillar cisternae of the endoplasmic reticulum away from the rhabdome, and a movement of mitochondria towards the rhabdome. To examine whether the microtubule cytoskeleton could be involved in these organelle movements, we have analysed the distribution of the microtubule-dependent motor proteins kinesin and cytoplasmic dynein in the retina of the locust Schistocerca gregaria. Both kinesin and cytoplasmic dynein are associated with vesicular structures that are distinct from mitochondria and the submicrovillar endoplasmic reticulum. These results, together with the previous demonstration of a lack of microtubules in the cell area of light-dependent organelle movements, provide evidence that the microtubule cytoskeleton is not involved with light-induced organelle translocations.
