| Term | yellow ommatidium | ID (Ontology) | FBbt:02000001 (Fly Anatomy) | |||||||||||
| Definition | Ommatidial subtype with stochastic distribution throughout the retina making up about 70% of all non-dorsal margin ommatidia. This ommatidial subtype is specialized to detect longer wavelengths (far UV + green).[ FlyBase:FBrf0180690 ] | |||||||||||||
| Comment | The yellow ommatidium expresses the far ultraviolet-specific opsin Rh4 (FBgn0003250) in photoreceptor R7 cells and the green-sensitive Rh6 (FBgn0019940) in photoreceptor R8 cells (Wernet and Desplan, 2004). | |||||||||||||
