When expression is driven by Scer\GAL4twi.PGa a few ectopic caudal visceral mesoderm cells form in the head mesoderm. The adhesive properties of the mesoderm are altered.
Scer\GAL4twi.PGa, bynUAS.cKa has head mesoderm phenotype, enhanceable by Scer\GAL4twi.PGa/fkhUAS.cRa
When expression of fkhScer\UAS.cRa and bynScer\UAS.cKa are driven together by Scer\GAL4twi.PGa there is a drastic increase in the number of anteriorly derived ectopic caudal visceral mesoderm cells form from the head mesoderm.
Scer\GAL4447.2/bynUAS.cKa partially rescues byn5
