Expression of GEFmesoDHPH.Scer\UAS using the SG30 driver (which combines Scer\GAL4how-24B and Scer\GAL4twi.PG) results in pupal death.
Expression of GEFmesoDHPH.Scer\UAS using Scer\GAL4nullo.PG or Scer\GAL4V3 severely impairs invagination of the mesoderm.
Scer\GAL4en-e16E-mediated expression of GEFmesoDHPH.Scer\UAS causes loss of crossveins.
