Shortening of the hindgut in otp mutants. Anti-Otp- (red) and anti-Crumbs- (Crb) (green) antibody staining of stage 16 wild-type embryos (a), homozygous otp1024 (b), otp13064 (c) and otpGT (d) embryos. In wild-type embryos (a) the borders of the large intestine (LI) are marked by red arrowheads, and the shortened hindgut of homozygous otp1024, otp13064, and otpGT embryos (b-d) is indicated by white arrowheads. All views are lateral views, anterior is to the left
