Fig. 4. Expression of PBP1 and GOBP2 in male and female antennae, in whole mount. (A–F) Bisected antennae of male (m; A–D) and female (f; E,F) adult M. sexta are shown probed with antisense RNA encoding PBP1 (P) or GOBP2 (G2). Insert diagrams indicate the orientation of the bisection. (C) shows details of cells of the mid-annular region expressing PBP1 (D, arrows). (G,H) Control in situ hybridizations (Con). Arrows in (G) indicate holes through the cuticle belonging to the long trichoid sensilla and through which olfactory dendrites pass to enter sensillum hairs. Tissue was from pharate adult animals. Size bar, 150 µm (A,B,E,F); 411 µm (C); 26 µm (D); 125 µm (G,H).
