Fig. 3. Pattern of endogenous eve expression in embryos expressing full-length Knirps 1-429 (A-D) and CtBP-independent region of Knirps 1-330 (E-G). Phenotypes of increasing severity are illustrated. Class I pattern (A,E), repression of stripe 3; Class II (B,F), repression of stripe 3 and 7; Class III (C,G) repression of stripe 3,4,6 and 7; Class IV, all stripes repressed except stripe 5. Endogenous eve patterns were visualized by in situ hybridization; embryos are oriented with anterior towards the left, dorsal side upwards. More severe phenotypes were produced by expression of full-length Knirps 1-429 than Knirps 1-330, as documented in Table 1.
