| Definition | Cluster of four extra-retinal Rh6-expressing, green-light sensitive photoreceptor cells located between the eye and the optic lobe (Jean-Guillaume and Kumar, 2022). It is found beneath the basement membrane, at the posterior margin of the compound eye, near to the equator. There is one of these on each side (Jean-Guillaume and Kumar, 2022). It is derived from the Rh5-expressing cells of the larval Bolwig organ, which switch their rhodopsin expression during pupal development (Jean-Guillaume and Kumar, 2022). It participates in entrainment of the molecular clock (Jean-Guillaume and Kumar, 2022).[ FlyBase:FBrf0111143 FlyBase:FBrf0152146 FlyBase:FBrf0248270 FlyBase:FBrf0255165 ] | |||||||||||||
