Fig. 9. ß-galactosidase expression directed by peripodial reporter
constructs persists in adult heads. (A) Diagram showing front and
back of adult head with relevant structures labeled. Modified from Bryant
(Bryant, 1978). Prst indicates
Proximal rostral sensilla. (B-F) Histochemical detection of
ß-galactosidase activity in B, dpps-hc-
lacZ, anterior view. (C) Same construct, posterior view. Arrows
represent Prst. Expression of (D) opa02 lacZ, (E) opa03 lacZ
and (F) opa04 lacZ.
