UASt regulatory sequences drive expression of p38b tagged with Tag:GST.
Scer\GAL4Act.PU/p38bUAS.Tag:GST rescues p38bd27
Expression of p38bScer\UAS.T:Sjap\GST under the control of Scer\GAL4Act.PU rescues the "black dot" phenotype seen in the hindgut of p38bd27 mutant larvae on normal food and food supplemented with either 0.1M or 0.2M NaCl.
