Deletion of T48 sequences.
Stage 6 mutant embryos show apical flattening of mesoderm cells, but apical constriction of these cells is delayed, resulting in a thick placode rather than an indentation on the ventral size of the embryo.
T48CC1.2, T48CC1.2, ctaR10, ctaR10 is a suppressor of epithelium | embryonic stage phenotype of moat2A
T48CC1.2, ctaR10, moat2A has ventral furrow phenotype
Homozygous Df(3R)CC1.2 embryos derived from homozygous ctaR10 females fail to make a ventral furrow.
