Rhomboid Loss (IMAGE) Society for Neuroscience Caption Loss of rhomboid (left) causes loss of rh5 (red) expression in R8 cells of Drosophila retina, and causes mispairing of Rh3 (blue) and Rh6 (green) in adjacent photoreceptors. Ectopic expression of rhomboid (right) causes mispairing of rh4 (blue) with rh5 (red), in addition to normal pairing with rh6 (green). See the article by Birkholz et al. for details.
