General Information
Term Rh5 photoreceptor of Bolwig organ ID (Ontology) FBbt:00100100 (Fly Anatomy)
Definition Cholinergic photoreceptor cell of the larval Bolwig's organ that expresses the blue-absorbing rhodopsin Rh5 (lambda[max] = 437nm; FBgn0014019). Fibers pass along the Bolwig nerve and terminate in the intermediate larval optic neuropil (Larderet et al., 2017). Some neurites bypass the larval optic neuropil and project to the adjacent ipsilateral central brain (Keene et al., 2011). Their projections in the larval optic neuropil have been shown to overlap with serotonergic arborizations (Rodriguez Moncalvo and Campos, 2005) and with the dendrites of pacemaker lateral neurons (LNs) (Keene et al., 2011; Mazzoni et al., 2005). It changes its Rhodopsin expression and becomes an eyelet photoreceptor cell during pupal development (Jean-Guillaume and Kumar, 2022). There are about four of these per Bolwig organ (Jean-Guillaume and Kumar, 2022).[ FlyBase:FBrf0144829 FlyBase:FBrf0184213 FlyBase:FBrf0190156 FlyBase:FBrf0213587 FlyBase:FBrf0237760 FlyBase:FBrf0255165 ]
Also Known As "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).
