Larvae do not survive a 30 minute heat shock. Rare adult escapers exhibit irregular ommatidial rows, fused ommatidia and duplicated interommatidial bristles.
E2f1hs.PA is a suppressor of embryonic/larval salivary gland | embryonic stage phenotype of Cdk1UAS.cHa, CycAUAS.cHa, Scer\GAL4l(1)BP-1
The inhibition of endoreplication in the salivary gland caused by coexpression of both CycAScer\UAS.cHa and cdc2Scer\UAS.cHa under the control of Scer\GAL4l(1)BP-1 is reversed if the larvae are also expressing E2fhs.PA.
