Figure 7.

Expression of bkh in the whole mesoderm rescues the heart phenotype. a and b represent two different plans of focus on the same embryo, homozygous for the Df(2R)47A deficiency probed with the anti-EC11 antibody (a) and the anti–Fas II antibody (b). The class II bkh cDNA under the control of 24B-GAL4 is expressed in the whole mesoderm. The heart appears similar to that in wild-type embryos (a) while the nervous system remains disrupted (b). In both views, anterior is left and dorsal is up.
