Calcium homeostasis in photoreceptor cells of Drosophila mutants inaC and trp studied with the pupil mechanism.

Visual neuroscience - 1 Jan 2000

Hofstee C A, Stavenga D G

Abstract excerpt

The light-driven pupil mechanism, consisting of an assembly of mobile pigment granules inside the photoreceptor cells, has been investigated by in vivo reflection microspectrophotometry in wild type (WT) Drosophila and in the photoreceptor mutants inaC and trp. The pupillary response of a dark-adapted WT eye to a step in light is a monophasic reflectance increase reaching a plateau after ca. 15-s light...
