caps::trntrnEd.capsId.UAS/Scer\GAL4twi.PG is an enhancer of tracheal dorsal trunk primordium phenotype of trn28.4
Expression of caps::trntrnEd.capsId.Scer\UAS under the control of Scer\GAL4twi.PG enhances the tracheal defects of trn28.4 embryos so that these embryos show 11.2% more dorsal trunk interruptions than trn28.4 mutants.
