Function of sal and svp in Rh5- and Rh6-subtype specification. (A) High-magnification image of stage 17 wild-type BO labeled with anti-Rh5 (green), anti-Rh6 (red), and anti-Elav (blue). (Inset) Three-dimensional reconstruction of the BO PRs. (B) High-magnification image of stage 17 svp mutant BO labeled with anti-Rh5 (green), anti-Rh6 (red), and anti-Elav (blue). A total of 12 PRs are found, all expressing Rh5. (Inset) Three-dimensional reconstruction of the BO PRs. (C) High-magnification image of stage 17 sal mutant BO labeled with anti-Rh5 (green), anti-Rh6 (red), and anti-Elav (blue). A total of 12 PRs are detected: Eight express Rh6, whereas four are devoid of anti-Rh5 or anti-Rh6 staining. (D) High-magnification image of stage 17 wild-type BO labeled with anti-Chp (green), anti-Sal (red), and anti-Elav (blue). Four cells express Sal (arrow). (E) High-magnification image of stage 17 svp mutant BO labeled with anti-Chp (green), anti-Sal (red), and anti-Elav (blue). All PRs express Sal (arrow). (F) High-magnification image of third instar larva so-Gal4,UAS-svp BO labeled with anti-Rh5 (green), anti-Rh6 (red), and anti-Elav (blue). All PRs are labeled by anti-Rh6; no anti-Rh5 staining is detected. (G) Axonal projections of larval PRs in sal mutant stage 17 embryos labeled with anti-FasII (green) and anti-Rh6 (red). Axonal terminations are properly formed (arrow). (H,I) High-magnification image of termini of larval PRs in sal mutant labeled with anti-FasII (green) and anti-Rh6 (red). Projections of “empty” PRs are devoid of Rh6 expression but labeled with the general marker FasII (cf. arrows in H,I).
