Fig. 7. E-cadherin interacts genetically with Egfr signalling. (A,B) Rotational defects in S⁵⁶⁷¹/shg^IG29 adult eye sections. Rotational defects of S⁵⁶⁷¹/+ eyes are significantly enhanced by halving the dose of E-cadherin (compare Fig. 7A,B with Fig. 2C,D). (C) Table showing interactions between Star and shotgun, wing blister and myospheroid. `No.' indicates the number of eyes scored for each genotype. Only shotgun alleles significantly enhance the rotational defects of the Star heterozygote. Significant differences from S/+ are indicated in bold type (P<0.05).
