No indications of dominant-negative effects are observed as a consequence of the overexpression of JIL-1Hsp83.T:Avic\GFP.
Expression of JIL-1Hsp83.T:Avic\GFP rescues both the autosomal and male X polytene chromosome phenotypes seen in JIL-1z2 homozygous larvae. The Hsp83 driver is leaky and therefore no heat shock is required.
