| Term |
Rh5 photoreceptor of Bolwig organ |
ID (Ontology) |
FBbt:00100100 (Fly Anatomy) |
| Definition |
Photoreceptor cell of the larval Bolwig organ that expresses the blue-absorbing rhodopsin Rh5. It follows the Bolwig nerve and terminates in the intermediate larval optic neuropil, where it outputs mainly onto visual projection interneurons (Larderet et al., 2017). Some neurites bypass the larval optic neuropil and project to the adjacent ipsilateral central brain (Keene et al., 2011). It is involved in light-avoidance behavior (Keene et al., 2011). It changes its Rhodopsin expression and becomes an eyelet photoreceptor cell during pupal development (Jean-Guillaume and Kumar, 2022). There are four of these cells per Bolwig organ (Hartenstein et al., 2019; Jean-Guillaume and Kumar, 2022). Their somas are clustered posteroventral to those of the Rh6 photoreceptors (Hartenstein et al., 2019).[ FlyBase:FBrf0213587 FlyBase:FBrf0237760 FlyBase:FBrf0243080 FlyBase:FBrf0255165 ] |
| Also Known As |
"Bolwig organ Rh5-PRC" ; "Rh5-expressing photoreceptor of Bolwig's organ" |
| Comment |
Neurotransmitter type was assessed in two ways: by double labelling of cells with an acetylcholine GAL4 driver (FBtp0014830) and a Rh5 antibody; by double labelling cells with drivers for Rh5 (FBtp0013993) and an acetylcholine antibody (Keene et al., 2011). |
