Fig. 4. Expression pattern of Calliphora rhodopsins Rh3, Rh5 and Rh6.
Longitudinal (A,C) and cross (B,D) sections through the compound eye of
Calliphora were labelled with antibodies specific for
Calliphora Rh3, Rh5, Rh6 and with rhodamine-coupled phalloidin. (A,B)
Labelling of Rh5 (green), Rh6 (blue) and the actin cytoskeleton of the
rhabdomeres (red). The overlay of Rh6 (blue) and actin (red) labeling appears
purple. Rh5 and Rh6 are detected in the basal part of the retina. The cross
section in B is at the level of R8 cells. (C,D) Labelling of Rh3 (green), Rh6
(blue) and the actin cytoskeleton of the rhabdomeres (red). Rh3 and Rh6 are
detected in the apical and basal portion of the retina, respectively. The
cross section in D is at the R7 cell level in which Rh3 but not Rh6 is
detected. Scale bars, (A,C) 80 µm; (B,D) 8 µm.
